Thanx Daniel, but use of these methods requires a 'Point2D' and 'Point' instance, which i don't know how to construct at that point of time. I have a Plot instance, a Rectangle2D instance and ValueAxis and DomainAxis instances.

Ok, i found it. It goes as follows.. //.... find origin x = plot.getRangeAxisEdge().coordinate(dataArea, RectangleEdge.LEFT); y = plot.getRangeAxisEdge().coordinate(dataArea, RectangleEdge.BOTTOM); //..use origin Or if someone has a better way to do it, plz post it here. Thanx.

Q1] How to find (x,y) coordinate of the origin of a plot.
Q2] How to find the hieght/width of the plot ?

If you are using a CategoryPlot to draw the chart, then you can use setSeries() method of the CategoryItemRenderer class. It will allow you define colors for each different series., hence making the bars look different.

For every different series in the chart, you see a diiferent colored bar. So, if there are two series then their colors would be Blue and Red by default. Changing this default setting is simple, eg, if you are using a CategoryPlot to draw a stacked bar chart, then //get the renderer from CategoryPlo...

Can we have a categorized FAQ. It will be easier to jump to a certain category of questions rather than browsing the whole list. It may have example links to previous posts as well.

regards,

Try "categoryAxis.setCategoryMargin(x)" to allow some gap between categories if you are using a CategoryPlot.

See, if we create overlaid bar-line charts using one CategoryPlot and two CategoryData sets (one for Bar and one for Line), we can define rendering orders of datasets using "setDatasetRenderingOrder" method of CategoryPlot class. Which takes care of what overlays what. I don't know if we can define ...

Adding to the previous problem: The distance in pixels means: IF (x,y) is the starting location of annotation on the plot, then x is the distance from RangeAxis and y is the distance from DomainAxis, both in pixels. Given the fact that we only have category names as column keys in CategoryPlot, is t...

I have to create this effect: A 3D bar chart with pointer annotations. The condition is that i have to use a CategoryPlot, and a Bar3DRenderer to draw the chart. | | | | | | | | _________ | | /_________/| | | | | | | | | <--------------- Your current coverage | | | | | | | | | | | |____________| | |...
