X11 error using JFreechart on Sun Solaris

[Fabien Boulesteix]

I'm using JFreechart 0.5.5 on Sun Solaris and when I create the chart, I have the following error :
Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

The code I am using to create the chart is :
JFreeChart myChart = JFreeChart.createVerticalBarChart(myDataSource);
//Put a white background
myChart.setChartBackgroundPaint(new GradientPaint(0, 0, new Color(235, 235, 235), 1000, 0, new Color(235, 235, 235)));
//Set the color is the series
myChart.setSeriesPaint(SERIESPAINT);
//Set the title
String title="";
myChart.setTitle(title);

Plot myPlot=myChart.getPlot();
Axis myHorizontalAxis=myPlot.getAxis(Plot.HORIZONTAL_AXIS);
myHorizontalAxis.setLabel("");

/**
* Add the possibility to view labels verticaly
* This is a protected attribute (verticalCategoryLabels) of the
* HorizontalCategoryAxis object.
* I have to modify the code of JFreechart or to wait for the next release
* Current release 0.5.5
* 16/10/2000 : I have modify the code of JFreechart
*/

//Set the label of the horizontal axis to be view verticaly
HorizontalCategoryAxis HorizontalCategoryAxis = (HorizontalCategoryAxis) myPlot.getHorizontalAxis();
HorizontalCategoryAxis.setVerticalCategoryLabels(true);


Axis myVerticalAxis=myPlot.getAxis(Plot.VERTICAL_AXIS);
myVerticalAxis.setLabel("CHF");


The value of the variable SERIEPAINT is :
new Paint[] {new Color(206, 45, 69),new Color(102, 153, 0),new Color(102, 102, 204),new Color(255, 102, 0),Color.red,Color.blue,Color.green,Color.yellow,Color.cyan};

I have modify the code of the HorizontalCategoryAxis class to add the method setVerticalCategoryLabels.


Thanks for your help.

Hello Fabien,

the error you encountered has nothing to do with JFreeChart.

There are two possibilities for the error:

1. You have not set the DISPLAY variable correctly for your X-Display
Enter the following to check:

# env

you should now see the setting of your DISPLAY variable.

The correct setting is hostname:display (e.g. myhost:0.0)

2. You have not allowed remote access to your X-Server
You can do this by entering xhost +Hostname

Regards,

Alexander
