Pie chart on teechart java v2
Pie chart on teechart java v2
I'm trying the evaluation version 2 and when I try to print or write the image the program goes into the dump. I also tried the applet in the folder examples/swing but also when selecting the styles pie the applet freezes.
Thanks for any suggestions.
This is the error
java.lang.NullPointerException

Hi newsoft,
I'm not able to reproduce the issue here using TeeChart.Features.jar demo nor in a simple example project (see code below). Could you please let us know the exact steps we should follow in the demo or modify code snippet below so that we can reproduce the problem here?
Thanks in advance.

Code: Select all
try {
commander1.setChart(tChart1.getChart());
Pie pie1 = new Pie(tChart1.getChart());
pie1.fillSampleValues();
tChart1.getExport().getImage().getJPEG().save("c:\\temp\\piejava.jpg");
} catch (IOException ex) {
Logger.getLogger(DesktopApplication1View.class.getName()).log(Level.SEVERE, null, ex);
}

Hi Narcís,
I use TeeChart.Swing.jar v2 lib evaluation version, this is my example:
The java version is build 1.6.0_11-b03.
Let me remind you that in the example Examples/Swing/Applet/TChartAppletDemo.htm when I select the pie chart applet hangs.
Thank you for your replay.

Hi newsoft,

Your code is very similar to the code snippet I posted. Does it work fine at your end? Could you please modify it so that we can reproduce the problem here?

It's not clear to us which is the TeeChart version you are using. This seems to be the Java Runtime Environment version number. At Steema Software's version info page you can see the exact releases for each TeeChart version. Below you can find TeeChart for Java v1 and v2 release notes:The java version is build 1.6.0_11-b03.

We will investigate this but works fine here:Let me remind you that in the example Examples/Swing/Applet/TChartAppletDemo.htm when I select the pie chart applet hangs.

Hi Narcís,
the version is not the same, the link that you have specified using the evaluation version 2.0.0.701 while the one I use is the evaluation 2.0.0.771, downloaded from your site. I think this is the problem, can you tell me where to download the TeeChart.Swing.jar 2.0.0.701 version.
Thank you.

Hi newsoft,
Thanks for the information. This is possibly because the Evaluation version could be built later and hence small difference in build number. However, could you please check if the code snippet I posted works fine for you or can you modify it so that we can reproduce the problem here?

Hi Narcís,
Sorry if I do not do other tests, but in the version I downloaded the applet hangs when you select the pie chart, it is enough that you download, unzip and run the demo applet in the folder Examples/Swing/Applet, you'll see that it crashes. Basically if you try the version 2.0.0.771 to 2.0.0.701 place you'll see that the problem occurs. You can also try to http://www.studiomuscella.it/teechart/T ... etDemo.htm I have done from different computers and the problem still occurs.
Thank you and sorry for my English, I am using a translator and my little knowledge of the language.

Hi newsoft,
Thanks for the information.
I can't reproduce this. Neither using the demo you posted nor using our current source code so you may expect the issue being solved for the next maintenance release. You could also try checking if there's any Java upgrade that can be applied to your environment.
