Re: Superimpose 2 block chart

But that will set the alpha for every dataset, doesn't it ? Or I have to create 1 plot for each dataset ?

Superimpose 2 block chart

Hello !
I'm trying to superimpose 2 chart with different alpha value but only one of them are visible ...
I'm using a XYBlockRenderer and I was wondering if this type of chart enable me to do that.

Is it possible to display 2 chart with this type of renderer ?

Re: Idea to distinguish items in XYBlockRenderer

What david was saying is to override this methode like this : @Override public void drawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crossha...

Re: Symbol Axis rotation

This isn't totally working I think (It's more that I didn't totally understand how it work) but with a ValueAxis you can do this :

Re: Setting custom domain axis tick labels

It's only for a Bar plot ? if that the case the name of the column should be enough ?

Code: Select all

DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.addValue(newData,strRow,strCol);

Re: Chart does not show data after adding a new panel

If you can show us the part of the code when you add your ChartPanel into your layout, because juste with that I think that you have made a mistake like you add 2 chart at the same place

Re: ChartEntity on Right Mouse Release (Button 3)

If you look at the source code you can that JFreechart assigned the right click to the PopUpMenu : 1585: else if (e.isPopupTrigger()) { 1586: if (this.popup != null) { 1587: displayPopupMenu(e.getX(), e.getY()); 1588: } 1589: } I'm not sure what you want to do ^^ Here you can find the full code : ht...
