Zoom Problem

[Fran Tonello]

Hi Gang,

When I set chartPanel.setMouseZoomable(true), we start seeing the following error when the user zooms-in repeatedly:

Range(double, double): require lower <= upper

This happens after the user has zoomed in a bunch of times and the chart has auto-range turned off. (Where "bunch" is typically: 5 <= bunch <= 10.)

Hi Fran,

I've tried to reproduce this problem, but couldn't get it to happen. Which version are you using, JDK and OS etc?

Regards,

Hi Dave,

We're using JRE 1.4.0 and 1.4.1, JFreeChart 0.9.6. The problem occurs on line charts with auto range turned off and the following executed before every update:

Code: Select all

if ( (! plot.getVerticalValueAxis().isAutoRange()) ||
     (maxValue < plot.getVerticalValueAxis().getMaximumAxisValue()) ) {
  plot.getVerticalValueAxis().setRange(0, maxValue);
  plot.getVerticalValueAxis().setMinimumAxisValue(0);
  plot.getVerticalValueAxis().setMaximumAxisValue(maxValue);
}

With the above code in place, here's the stack trace you get:

Code: Select all

Hope this helps!

Oh, and we see the problem on Solaris and Windows. We didn't try it on Linux, but from the trace, it looks like it'll happen there, too.

I see the very same problem/stack trace when Zooming in on a graph line.....

AFAIK there has to be a graph line showing, i.e. zoom in on a vertex continuously....

My set up is :

- java version "1.4.1_02"
- Windows 2000 SP3

I can get the PRException, but not the other one. Can anyone post a demo application that fails? It could be that the charts I'm using to test with have something set up that doesn't trigger the bug...
