Hide certain series in the legend

Post by andreak » Fri Nov 05, 2004 8:31 am

Hi. Is it possible to hide some series in the legend. Say I have 3 TimeSeries, and I only want two of them to appear in the legend, how do I do this? If it's not possible, is there a nice work-around?

One quick solution is to disable the showing of the legend in the graph and draw your own one. Another solution is to override the legend class, i do not know which one neither do i know how to implement. Maybe you can figure it out by looking @ the source code.

You may revise the source code of jfreechart.
Commonly u should revise the getLegendItems() method in plot.
The following is a simple sample for PiePlot:

[ public LegendItemCollection getLegendItems() {

LegendItemCollection result = new LegendItemCollection();

List keys = null;
if (this.dataset != null) {
keys = this.dataset.getKeys();
int section = 0;
Iterator iterator = keys.iterator();
while (iterator.hasNext()) {
Comparable key = (Comparable) iterator.next();
Number n = this.dataset.getValue(key);
if (n != null || !this.ignoreNullValues) {
String label = key.toString();
String description = label;
Shape shape = null;
Paint paint = getSectionPaint(section);
Paint outlinePaint = getSectionOutlinePaint(section);
Stroke stroke = getSectionOutlineStroke(section);

LegendItem item = new LegendItem(
label, description, shape, true, paint, stroke, outlinePaint, stroke
);

// result.add(item);
// if u want to disable the 2nd legendItem ,just to:
if(section!=1)
result.add(item);
section++;
}
}
}

return result;
}
][/code]

If you are using CategoryPlot or XYPlot you can use the setFixedLegendItems(LegendItemCollection items) method

setFixedLegendItems() and CombinedDomainCategoryPlot

Post by logimine » Tue Feb 08, 2005 8:25 pm

It ' s easier to remove items in the LegendItemCollection :

LegendItemCollection legend = plot.getLegendItems();
Iterator iterator=legend.iterator();
while(iterator.hasNext()){
LegendItem item=(LegendItem)iterator.next();
if(item.getLabel().equals("serie name"))
iterator.remove();
}
plot.setFixedLegendItems(legend);

!!! if you use CombinedDomainCategoryPlot, you need to refer the sub plots.

I use below code to hide certain series based on my application criteria;

Code: Select all

plot.getRenderer().setSeriesVisibleInLegend(seriesIndex, Boolean.FALSE, true);
If above code doesn't work make sure series are set to visible before calling above method.
