Set the size of a chart

Hi.

I can't find the method by which one can set the size of a chart.

I add my chart at a chart panel. Then the chart panel is added at a scroll pane which settles in a frame (jInternalFrame actually). The scroll pane creates vertical scroll bar because the chart is quite bigger than itself. I need to make the chart fit exactly in the scroll pane.

Can anyone help?
Thanks a lot.

If you want the ChartPanel to be exactly the same size as the JScrollPane, then the JScrollPane is redundant...just put the ChartPanel in the same place (that is, replacing) the JScrollPane.

I had to redefine the height of my chart (that I use in a scrollpanel as well), so I use the following command :

protected final static int myHeight2G = 325;
myChartPanel.setPreferredSize(new Dimension(ChartPanel.DEFAULT_WIDTH, myHeight2G));

I also modify default min max size to allow bigger chart (smaller is less necessary) :

protected final static int myMinSize = 100;
protected final static int myMaxSize = 2048;
myChartPanel.setMinimumDrawWidth(myMinSize);
myChartPanel.setMaximumDrawWidth(myMaxSize);
myChartPanel.setMinimumDrawHeight(myMinSize);
myChartPanel.setMaximumDrawHeight(myMaxSize);
