JfreeChart 0.6 and IBM Power P520 Expres

[micheljperez]

Greetings,

I'm making the migration of an application developed with jfreechart, I guees 0.6 version.A little bit old...
I'm using the Virtual Machine form IBM:
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 Linux ppc64-64)
The problem is that the graphics is generated more opaque and whitout definition.



I'm using RHEL 5

What could I do ?
Thank you

Thanks for your help

I don't understand the question.

I developed an app with jFreeChart 0.6, and always I have been used a jvm based on x86, right now I migrated my app to ppc64 IBM, and must use its JVM (IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 Linux ppc64-64), after the migratión the graphcis isn't weel definied, its works, but looks lightly fuzzy. I used tomcat 6 and jdk 6.

Thanks

After the migration, the chart is now rendered with aliasing enabled. Therefore lines and text appears blurred.

Define the aliasing by configuring the Graphics2D object. You can change the defaults via Graphics2D#setRenderingHints. Which defaults are used is platform dependent and may even change with JDK releases.

Look Dave, I can see you're really upset about this. I honestly think you ought to sit down calmly, take a stress pill, and think things over.

Thanks for your help, english isn't my mother language, and express that problem was a little bit difficult.
So, I have made the changes, but the problem continues, here the changes that I have made:

JFreeChart myChart = JFreeChart.createTimeSeriesChart(myXYDS);
chartImage = new BufferedImage((ancho - borde),(largo - borde), BufferedImage.TYPE_BYTE_INDEXED);

g2 = (Graphics2D)chartImage.getGraphics();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT);

try {
myChart.draw(g2, new Rectangle2D.Double(0, 0, ancho -2, largo -2));
} catch (Exception e){
System.out.println("[Plotter.generateTimeSeriesChart] ("+titulo+") Exception: "+e);
} catch (Error e){
System.out.println("[Plotter.generateTimeSeriesChart] ("+titulo+") Error: "+e);
}

Thanks in advance for your help

Greetings,

It's me again, excuse me, but I same the same problem, Here is my code.

JFreeChart myChart = JFreeChart.createTimeSeriesChart(myXYDS);
chartImage = new BufferedImage((ancho - borde),(largo - borde), BufferedImage.TYPE_BYTE_INDEXED);

RenderingHints rendering=null;
g2 = (Graphics2D)chartImage.getGraphics();
hashAliasing.put(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
hashAliasing.put(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
rendering=new RenderingHints(hashAliasing);
g2.setRenderingHints(rendering);


try {
myChart.draw(g2, new Rectangle2D.Double(0, 0, ancho -2, largo -2));
} catch (Exception e){
System.out.println("[Plotter.generateTimeSeriesChart] ("+titulo+") Exception: "+e);
} catch (Error e){
System.out.println("[Plotter.generateTimeSeriesChart] ("+titulo+") Error: "+e);
}

Pleace, help me...

Have you tried another image type? I normally use BufferedImage.TYPE_4BYTE_ABGR.

Have you tried another image type? I normally use BufferedImage.TYPE_4BYTE_ABGR.

That's a good suggestion. But if that doesn't work, can you post screenshots before and after?
