Hi,
I am using cewolf 1.1, prepared by ulfdittmer. I am using the meter chart for my application. But making showlegend to false for meter chart does not hide the legend. Can anybody please tell me how to hide the legend.
Thanks

Welcome to JavaRanch.

The various meter charts never honored that parameter. I've uploaded a new version that fixes this, and which also has a postprocessor (MeterEnhancer) for setting some other parameters.

Thanks for your solution. My new problem is that,While using MeterPostProcessor , I have increased the BasicStroke of MeterInterval to 20.0f. But in case of display the chord is trimmed at upper level.
I am attaching the code for meter postprocessor for processchart function:

public void processChart (Object chart, Map params) {
MeterPlot plot = (MeterPlot) ((JFreeChart) chart).getPlot();
double min = 0;
double max = 180;
plot.setMeterAngle(180);
plot.setNeedlePaint(Color.BLACK);
plot.setDialBackgroundPaint(Color.white);
plot.setDrawBorder(true);
plot.setDialShape(DialShape.CHORD);
//plot.setDialBackgroundPaint(Color.ORANGE);
plot.setOutlineVisible(true);
plot.setRange(new Range(min, max));
plot.addInterval(new MeterInterval("Normal",new Range(0, 60),Color.green, new BasicStroke(20.0f, BasicStroke.CAP_BUTT, BasicStroke.CAP_BUTT), null));
plot.addInterval(new MeterInterval("Warning",new Range(60, 120),Color.yellow, new BasicStroke(20.0f,BasicStroke.CAP_BUTT, BasicStroke.JOIN_MITER), null));
plot.addInterval(new MeterInterval("Critical",new Range(120, 180),Color.red, new BasicStroke(20.0f,BasicStroke.CAP_BUTT, BasicStroke.JOIN_MITER), null));
plot.valueToAngle(0.0f);
plot.setUnits("km/h");
}

Is the problem that not the full width is visible? If so, that's probably unavoidable. The chart drawing code does not take extra-wide graphics into account.

Yes, that's the problem. Can you suggest any alternative? Is it possible by ,putting negative values in stroke to produce the width inward. Though ,that does not work. But is it possible to do?
 
I agree. Here's the link: http://aspose.com/file-tools
