Setting Base for bar chart in version 0.9.16

[shamesh_joshi]

Hello all,
I am curently using jfreechart-0.9.16.jar. I have to set base for the bar chart, which i couldn't find how to do. so please anybody suggest me.. I can't upgrade to new version as I have to mend the chart and the chart was already using older version.
Regards,
Shamesh

You should get the source for the latest version of BarRenderer.java, and compare it to the BarRenderer.java file in 0.9.16. I don't recall how much has changed, but it should at least give you an indication of how you might be able to backport this feature.

Thank-x for the concern, can you please tell me where I can find the source file of both versions???

Thank you for the support. the problem is solved. It was easier than I thought.

Just extends BarRenderer add function calculateBarL0L1 to overwrite setting base.

protected double[] calculateBarL0L1(double value) {

double lclip = getLowerClip();
double uclip = getUpperClip();
double bb = this.base;
if (uclip <= 0.0) { // cases 1, 2, 3 and 4
if (value >= uclip) {
return null; // bar is not visible
}
bb = uclip;
if (value <= lclip) {
value = lclip;
}
}
else if (lclip <= 0.0) { // cases 5, 6, 7 and 8
if (value >= uclip) {
value = uclip;
}
else {
if (value <= lclip) {
value = lclip;
}
}
}
else { // cases 9, 10, 11 and 12
if (value <= lclip) {
return null; // bar is not visible
}
bb = lclip;
if (value >= uclip) {
value = uclip;
}
}
return new double[] {bb, value};
}
