RE: [jCharts-users] AxisChartDataSet Constructor paints parameter

[Lapinski, M. (Research) <lap...@cr...>]

Well in my case ill have to do the following:

	- implement the PreAxisValueRenderListener
	- pass it to the BarChartProperties using
addPreRenderEventListener()

What I not clear on is how to access the given Paints 
that are passed in the array.

What id like to do is make use of the array of Paints 
so that position in the array corresponds to the Color
sitting in the array. So for example the preRender() method
would look like this:

	
axisValueRenderEvent.getGraphics2D.setPaint(Paints[axisValueRenderEvent.getD
ataSetIndex()]);
	
The questions that remain are:
	- how to access the array of paints in the preRender() method?
	- does dataSetIndex correspond to the position of the piece of data
in the data array?
	  Ie data {{5, 10,15}} when the event comes with dataSetIndex of 1
this is the event for 
	  value 15?

-thank you

Some other charts need an Array.  Could we have overloaded the
Constructor...sure.  

in your case, simply pass: new Paint[]{ Color.blue }
