JFreeChart on Windows 7?

[Mike Keller]

I have heard of people successfully using the version of JFreeChart and JCommon that I have (1.0.13 and 1.0.16 respectively), but when I try running my application, the window where the chart panel should be is blank. It displays properly on Vista and XP. I am clearly doing something wrong, but I'm not sure what.

[pooo]

What java version are you using ?

[Mike Keller]

Whoops, I should have specified that in my first post.

I compiled it with JDK 1.6.0_14 (By compiled I mean into an executable JAR), and tried running it under both that and JRE 6 update 21, with the same results on both.

I have seen a jFreeChart based app run smoothly under windows, so whatever problem you have, it does not seem to be general.
Since you haven´t given any information about the app (JFree demo, something you have made, something that is using a database, Swing or SWT based, use of a specific LAF), I can only guess.
And my guess would by that your code is creating an exception under Windows7 that does not occur under the other systems. Are you seeing any exceptions?

[Mike Keller]

It does use Swing components, but those are displaying. It's only the JFreeChart items I can't see.

And I am not getting any exceptions.

Do the demos included with the distribution work?

[Mike Keller]

They do not, with the same problem that my own application has - the window comes up and remains blank, with no actual errors.

Perhaps there is some conflict with the video drivers. Try including one or both of these in the command line

Code: Select all

-Dsun.java2d.opengl=false
-Dsun.java2d.noddraw=true

That did the trick! Brilliant work!
