+## Customization
+
+Both the line and bar charts support a robust set of customization options. 
+
+The background of a bar or line chart can be set just like any other view:
+	
+	self.barChartView.backgroundColor = ...; // UIColor
+	self.lineChartView.backgroundColor = ...; // UIColor
+	
+Any <i>JBChartView</i> subclass supports the use of headers and footers (similiar to that of <i>UITableView</i>):
+
+	self.barChartView.footerView = ...; // UIView
+	self.lineChartView.headerView = ...; // UIView
+	
+Lastly, any JBChartView subclass can be collapsed or expanded programmatically via the <i>state</i> property. If you chose to animate state changes, a callback helper can be used to notify you when the animation has completed:
+
+	- (void)setState:(JBChartViewState)state animated:(BOOL)animated callback:(void (^)())callback;
+
+#### JBBarChartView
+
+A bar chart can be inverted such that it's orientation is top->down (including the selection view) by setting the following property:
+
+	@property (nonatomic, assign, getter=isInverted) BOOL inverted;
+
+By default, a chart's bars will be black and flat. They can be customized by supplying a UIView subclass through the <i>optional</i> protocol:
+
+	- (UIView *)barChartView:(JBBarChartView *)barChartView barViewAtIndex:(NSUInteger)index
+	{
+		return ...; // color of line in chart
+	}
+	
+If you don't require a custom UIView, simply supply a color for the bar instead:
+
+	- (UIColor *)barChartView:(JBBarChartView *)barChartView colorForBarViewAtIndex:(NSUInteger)index;
+	
+If a solid color isn't your cup of tea, you can expose a gradient to be applied across the entire chart:
+
+	- (CAGradientLayer *)barGradientForBarChartView:(JBBarChartView *)barChartView;
+
+Furthermore, the color of the selection bar (on touch events) can be customized via the <i>optional</i> protocol:
+
+	- (UIColor *)barSelectionColorForBarChartView:(JBBarChartView *)barChartView
+	{
+		return ...; // color of selection view
+	}
+	
+<b>Note</b>: The delegate will request a custom UIView, followed by a color and lastly a gradient. If nothing is supplied, a plain black bar will be used.
+	
+Lastly, a bar chart's selection events are delegated back via:
+
+	- (void)barChartView:(JBBarChartView *)barChartView didSelectBarAtIndex:(NSUInteger)index touchPoint:(CGPoint)touchPoint
+	{
+		// Update view
+	}
+
+	- (void)didDeselectBarChartView:(JBBarChartView *)barChartView
+	{
+		// Update view
+	}
+
+The <b>touchPoint</b> is especially important as it allows you to add custom elements to your chart during  selection events. Refer to the demo project (<b>JBarChartViewController</b>) to see how a tooltip can be used to display additional information during selection events.
+
+#### JBLineChartView
+
+The color, width and style of each line in the chart can be customized via the <i>optional</i> protocol:
+
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView colorForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // color of line in chart
+	}
+	
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView fillColorForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // color of area under line in chart
+	}
+	
+	- (CGFloat)lineChartView:(JBLineChartView *)lineChartView widthForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // width of line in chart
+	}
+	
+	- (JBLineChartViewLineStyle)lineChartView:(JBLineChartView *)lineChartView lineStyleForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // style of line in chart (solid or dashed)
+	}
+	
+Additionally, the line and fill color style can be customzized via the <i>optional</i> protocols (below). The line & fill color style apply to both selected and non-selected scenarios, meaning, if your line has a solid style, it's selected style will also be solid. 
+
+    - (JBLineChartViewColorStyle)lineChartView:(JBLineChartView *)lineChartView colorStyleForLineAtLineIndex:(NSUInteger)lineIndex
+    {
+        return ...; // color line style of a line in the chart
+    }
+    
+    - (JBLineChartViewColorStyle)lineChartView:(JBLineChartView *)lineChartView fillColorStyleForLineAtLineIndex:(NSUInteger)lineIndex
+    {
+        return ...; // color style for the area under a line in the chart
+    }
+
+If a solid color style is used, the following <i>optional</i> protocols can be implemented:
+
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView colorForLineAtLineIndex:(NSUInteger)lineIndex;
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView fillColorForLineAtLineIndex:(NSUInteger)lineIndex;
+ 	
+Gradient color styles require a CAGradientLayer to be returned:
+
+	- (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView gradientForLineAtLineIndex:(NSUInteger)lineIndex;
+	- (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView fillGradientForLineAtLineIndex:(NSUInteger)lineIndex;
+
+**Note**: gradients do not support multiple alphas. The alpha of gradient's first color be used throughout.
+
+Defining a gradient to use is simple and flexible. For example, this would be a horizontal gradient from blue to green:
+
+    CAGradientLayer *gradient = [CAGradientLayer new];
+    gradient.startPoint = CGPointMake(0.0, 0.0);
+    gradient.endPoint = CGPointMake(1.0, 0.0);
+    gradient.colors = @[(id)[UIColor blueColor].CGColor, (id)[UIColor greenColor].CGColor];
+    
+As mentioned prior, the same color style is duplicated for selection events:
+
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionColorForLineAtLineIndex:(NSUInteger)lineIndex;
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionFillColorForLineAtLineIndex:(NSUInteger)lineIndex;
+
+	- (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView selectionGradientForLineAtLineIndex:(NSUInteger)lineIndex;
+	- (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView selectionFillGradientForLineAtLineIndex:(NSUInteger)lineIndex;
+  
+The color and width of the selection view along with the color of the selected line can be customized via the <i>optional</i> protocols:
+
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView verticalSelectionColorForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // color of selection view
+	}
+	
+	- (CGFloat)verticalSelectionWidthForLineChartView:(JBLineChartView *)lineChartView
+	{
+		return ...; // width of selection view
+	}
+	
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionColorForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // color of selected line
+	}
+	
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionFillColorForLineAtLineIndex:(NSUInteger)lineIndex
+	{
+		return ...; // color of area under selected line
+	}
+	
+When using a gradient for the line or fill, a different gradient can provided for selection. If the selection gradient is not provided, it will default to the line and fill gradient provided for the line.
+    
+    - (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView selectionGradientForLineAtLineIndex:(NSUInteger)lineIndex
+    {
+        return ...; // gradient for selected line
+    }
+
+    - (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView selectionFillGradientForLineAtLineIndex:(NSUInteger)lineIndex
+    {
+        return ...; // gradient for area under selected line
+    }
+	
+By default, each line will not show dots for each point. To enable this on a per-line basis:
+
+	- (BOOL)lineChartView:(JBLineChartView *)lineChartView showsDotsForLineAtLineIndex:(NSUInteger)lineIndex;
+
+To the radius of each dot (default is 6x the line width, or 3x the diameter), implement:
+
+	- (CGFloat)lineChartView:(JBLineChartView *)lineChartView dotRadiusForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
+	
+To customize the color of each dot during selection and non-selection events (default is white and black respectively), implement:
+
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView colorForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;	
+	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionColorForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
+	
+Alternatively, you can supply your own UIView instead of using the default impelmentation:
+
+	- (UIView *)lineChartView:(JBLineChartView *)lineChartView dotViewAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
+	
+Custom dot views are automatically shown when selected unless the following is implemented:
+
+    - (BOOL)lineChartView:(JBLineChartView *)lineChartView shouldHideDotViewOnSelectionAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
+		
+As well, by default, each line will have squared off end caps and connection points. To enable rounded connections and end caps:
+
+	- (BOOL)lineChartView:(JBLineChartView *)lineChartView smoothLineAtLineIndex:(NSUInteger)lineIndex;
+		
+Furthermore, a line chart's selection events are delegated back via:
+
+	- (void)lineChartView:(JBLineChartView *)lineChartView didSelectLineAtIndex:(NSUInteger)lineIndex horizontalIndex:(NSUInteger)horizontalIndex touchPoint:(CGPoint)touchPoint
+	{
+		// Update view
+	}
+
+	- (void)didDeselectLineInLineChartView:(JBLineChartView *)lineChartView
+	{
+		// Update view
+	}
+	
+Upon selection, all other lines (+ fills) will be dimmed to 20% opacity (default). To change this value, implement:
+
+    - (CGFloat)lineChartView:(JBLineChartView *)lineChartView dimmedSelectionOpacityAtLineIndex:(NSUInteger)lineIndex
+    {
+        // Return new opacity (0.0 to hide completely, and 1.0 to have no effect)

+If you don't want a line to be selectable:
+
+	- (BOOL)lineChartView:(JBLineChartView *)lineChartView shouldIgnoreSelectionAtIndex:(NSUInteger)lineIndex
+	{
+		return NO; // Check line index
+	}
+	
+The <b>touchPoint</b> is especially important as it allows you to add custom elements to your chart during  selection events. Refer to the demo project (<b>JBLineChartViewController</b>) to see how a tooltip can be used to display additional information during selection events.

+State changes during a reload will be ignored. As well, subsequent calls to reloadData: or reloadDataAnimated: before any previous reloads are complete, will also be ignored.

+
+	@property (nonatomic, readonly) BOOL reloading;
+
+By default, the animation will complete in approximately 0.25 seconds. The animation duration is independent from the data model size. 
+
+**Note**: the above restrictions apply only to *animated* reloads, as non-animated reloads are synchronous.

 ## Customization

-Both the line and bar charts support a robust set of customization options. 
-
-The background of a bar or line chart can be set just like any other view:
-	
-	self.barChartView.backgroundColor = ...; // UIColor
-	self.lineChartView.backgroundColor = ...; // UIColor
-	
-Any <i>JBChartView</i> subclass supports the use of headers and footers (similiar to that of <i>UITableView</i>):
-
-	self.barChartView.footerView = ...; // UIView
-	self.lineChartView.headerView = ...; // UIView
-	
-Lastly, any JBChartView subclass can be collapsed or expanded programmatically via the <i>state</i> property. If you chose to animate state changes, a callback helper can be used to notify you when the animation has completed:
-
-	- (void)setState:(JBChartViewState)state animated:(BOOL)animated callback:(void (^)())callback;
-
-#### JBBarChartView
-
-A bar chart can be inverted such that it's orientation is top->down (including the selection view) by setting the following property:
-
-	@property (nonatomic, assign, getter=isInverted) BOOL inverted;
-
-By default, a chart's bars will be black and flat. They can be customized by supplying a UIView subclass through the <i>optional</i> protocol:
-
-	- (UIView *)barChartView:(JBBarChartView *)barChartView barViewAtIndex:(NSUInteger)index
-	{
-		return ...; // color of line in chart
-	}
-	
-If you don't require a custom UIView, simply supply a color for the bar instead:
-
-	- (UIColor *)barChartView:(JBBarChartView *)barChartView colorForBarViewAtIndex:(NSUInteger)index;
-
-Furthermore, the color of the selection bar (on touch events) can be customized via the <i>optional</i> protocol:
-
-	- (UIColor *)barSelectionColorForBarChartView:(JBBarChartView *)barChartView
-	{
-		return ...; // color of selection view
-	}
-	
-Lastly, a bar chart's selection events are delegated back via:
-
-	- (void)barChartView:(JBBarChartView *)barChartView didSelectBarAtIndex:(NSUInteger)index touchPoint:(CGPoint)touchPoint
-	{
-		// Update view
-	}
-
-	- (void)didDeselectBarChartView:(JBBarChartView *)barChartView
-	{
-		// Update view
-	}
-
-The <b>touchPoint</b> is especially important as it allows you to add custom elements to your chart during  selection events. Refer to the demo project (<b>JBarChartViewController</b>) to see how a tooltip can be used to display additional information during selection events.
-
-#### JBLineChartView
-
-The color, width and style of each line in the chart can be customized via the <i>optional</i> protocol:
-
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView colorForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // color of line in chart
-	}
-	
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView fillColorForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // color of area under line in chart
-	}
-	
-	- (CGFloat)lineChartView:(JBLineChartView *)lineChartView widthForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // width of line in chart
-	}
-	
-	- (JBLineChartViewLineStyle)lineChartView:(JBLineChartView *)lineChartView lineStyleForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // style of line in chart
-	}
-	
-Furthermore, the color and width of the selection view along with the color of the selected line can be customized via the <i>optional</i> protocols:
-
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView verticalSelectionColorForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // color of selection view
-	}
-	
-	- (CGFloat)verticalSelectionWidthForLineChartView:(JBLineChartView *)lineChartView
-	{
-		return ...; // width of selection view
-	}
-	
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionColorForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // color of selected line
-	}
-	
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionFillColorForLineAtLineIndex:(NSUInteger)lineIndex
-	{
-		return ...; // color of area under selected line
-	}
-	
-By default, each line will not show dots for each point. To enable this on a per-line basis:
-
-	- (BOOL)lineChartView:(JBLineChartView *)lineChartView showsDotsForLineAtLineIndex:(NSUInteger)lineIndex;
-
-To the radius of each dot (default is 6x the line width, or 3x the diameter), implement:
-
-	- (CGFloat)lineChartView:(JBLineChartView *)lineChartView dotRadiusForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
-	
-To customize the color of each dot during selection and non-selection events (default is white and black respectively), implement:
-
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView colorForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;	
-
-	- (UIColor *)lineChartView:(JBLineChartView *)lineChartView selectionColorForDotAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
-	
-Alternatively, you can supply your own UIView instead of using the default impelmentation:
-
-	- (UIView *)lineChartView:(JBLineChartView *)lineChartView dotViewAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;

-Custom dot views are automatically shown when selected unless the following is implemented:

-    - (BOOL)lineChartView:(JBLineChartView *)lineChartView shouldHideDotViewOnSelectionAtHorizontalIndex:(NSUInteger)horizontalIndex atLineIndex:(NSUInteger)lineIndex;
-		
-As well, by default, each line will have squared off end caps and connection points. To enable rounded connections and end caps:
-
-	- (BOOL)lineChartView:(JBLineChartView *)lineChartView smoothLineAtLineIndex:(NSUInteger)lineIndex;
-		
-Lastly, a line chart's selection events are delegated back via:
-
-	- (void)lineChartView:(JBLineChartView *)lineChartView didSelectLineAtIndex:(NSUInteger)lineIndex horizontalIndex:(NSUInteger)horizontalIndex touchPoint:(CGPoint)touchPoint
-	{
-		// Update view
-	}
-
-	- (void)didDeselectLineInLineChartView:(JBLineChartView *)lineChartView
-	{
-		// Update view
-	}
-	
-The <b>touchPoint</b> is especially important as it allows you to add custom elements to your chart during  selection events. Refer to the demo project (<b>JBLineChartViewController</b>) to see how a tooltip can be used to display additional information during selection events.
+Both the line and bar charts support a robust set of customization options. Read more about them <a href="Customization.md">here</a>. 

 ## Minimum & Maximum Values

 The min/max values are clamped to the ceiling and floor of the actual min/max values of the chart's data source; for example, if a maximumValue of 20 is supplied & the chart's actual max is 100, then 100 will be used. For min/max modifications to take effect, reloadData must be called.

+## Performance
+
+The nature of charting is to display all available information, unlike a UITableView, which can cache rows that are offscreen. JBChartView's performance will suffer if the number of data points exceed the  resolution of the device. The same issue exists with MKMapView, when hundreds of pins are supplied within a certain geographic area.  It's why Apple recommends clustering to avoid performance issues. As such, for large datasets, we recommend that your dataSource to supply a subset of points; clustering those that are close to one another.
