Hi Lochin,

Try something like:

LegendTitle lt = chart.getLegend(); 
lt.setItemFont(new Font("Arial", Font.PLAIN, 8));

Hi Sridhar,

The Applet is executed in the browser which is unaware of the Jxxx libraries. You have to use the ARCHIVE attribute of the APPLET tag to indicate the needed jar files:

Code: Select all

<APPLET code="demo.Applet1.class" ARCHIVE="comma separated list of jar files"></APPLET>

Hope it helps

Hi,

You don't have to worry about this, the StackedBar does it for you.

Months are the categories while Assigned and Unassigned are two series and therefore displayed in same bars with different colors.

Hi,

Sounds like this : http://www.jfree.org/phpBB2/viewtopic.php?t=14697

Try to set set the upper and lower margins of your domain axis, may be something like that:

Code: Select all

CategoryAxis axis = plot.getDomainAxis();
axis.setLowerMargin(0.0); 
axis.setUpperMargin(0.0);

Create a tooltip generator then assign it to the renderer with the setToolTipGenerator method.
For instance for a CategoryDataset based barchart:

Code: Select all

StandardCategoryToolTipGenerator tt = new StandardCategoryToolTipGenerator();
renderer.setToolTipGenerator(tt);

The plot is ThermometerPlot

For your first problem (legend color) have a look here

You could extend StandardCategoryItemLabelGenerator and override generateLabel() method to make it return null when the value is 0

Did you try with different browsers?
In my case tooltips work fine with Mozilla 1.7.3 but don't show up with Netscape 4.73

Try this:

Code: Select all

StandardCategoryURLGenerator("../servlet/ChartWindow?parent=LOAD","series","category"));

I had the same problem (with JFreeChart 1.0.0-pre2). To solve this I created a subclass of IntervalCategoryToolTipGenerator and modified the drawTasks method in GanttRenderer class. I have posted a feature request with the code : http://sourceforge.net/tracker/index.php?func=detail&aid=1183877&group...

In the non working example you create a renderer, change the colors create a plot, assign the renderer to the plot, and then you create a chart with ChartFactory.createStackedBarChart but when creating the chart you don't use the plot previously prepared because there is no plot parameter for the cr...

As written previously:

setLabelGenerator for lthe pie section label
setLegendLabelGenerator for the legend

build the format you need for each of them using StandardPieItemLabelGenerator class (different format if you want different label)

pmlb

I guess you could use the setLegendLabelGenerator method of the plot in the same way.
