Dynamic clickable legend

[truman]

Is it possible, in a line chart, to customize legend, having for each item a checkbox to show/hide items in chart?



thanks, bye

Yes. Take a look at HideSeriesDemo1 in the demo. If you have bought the Developer's Guide, you can view the source code.

Hi !

I reply because I wanted to do the same thing ( and I don't have the Developper's Guide ).

So I try to use this function : ( extract from the javadoc jfreechart/api/javadoc/index.html )

Code: Select all

public void setSeriesVisible(int series, java.lang.Boolean visible)

This is a part of my code :

Code: Select all

XYItemRenderer renderer = (XYItemRenderer) plot.getRenderer();	
renderer.setSeriesVisible(0, true);

It's seems to be good for me, but Eclipse doesn't agree :

The method setSeriesVisible(Boolean, boolean) in the type XYItemRenderer is not applicable for the
arguments (int, boolean)

Someone sees what's wrong ?

Edit : Me ...

I was searching in the wrong way ...
I have no errors with this code :

Code: Select all

XYItemRenderer renderer = (XYItemRenderer) plot.getRenderer();	
renderer.setSeriesVisible(1, new Boolean(true));
