Vertical label overlaps axes

[Marilyn Linton]

The demo that I downloaded with JFreeChart has the vertical labels overlapping the y-axis tick numbers in XY plots (I am running on a PC with Windows 98). This also occurs in my XY plots in my application.
Is there any way to avoid this.
Thank-you, Marilyn

Hi Marilyn,

Sorry to hear that you are having trouble with JFreeChart.

It would help me to diagnose the problem if you could send me a screen copy of the chart showing the problem (PNG/GIF/JPEG or whatever) and also some details of the Java Virtual Machine version you are running (the demo program includes a frame that displays all the information - just copy and paste that if you can).

Regards,

DG.

It must be 1.4beta 2 or windows 2000

The problem exhibits itself with JVM 1.3.0_02 (ships w/JBuilder5).

Works fine under 1.3.0-C and J2RE 1.3.0 IBM build ca130-20010330 (AIX).

I face the same problem with the demo (jfreechart-0.7.1). I have JBuilder5 on Win2000 machine.
Is there a workaround for this?

(I can e-mail the image is you would like.)

Thanks in advance.

[Dogbert]

The hack we came up with was in com.jrefinery.chart.VerticalNumberAxis's draw method. After it defines 'xx' in the 'if (verticalLabel) {' block we put:

// hack around a bug in JBuilder5's JDK:
String version = System.getProperty("java.version");
if (version.equals("1.3.0_02") || version.startsWith("1.4"))
xx -= labelBounds.getHeight() / 2;

Note that I don't know if this works with the latest version....
