Multiple line label in piechart

[nilesh]

in pieplot.java at drawLabel() function, there is code

Code: Select all

 if (this.sectionLabelType == NAME_AND_VALUE_LABELS) {
            label = data.getKey(section).toString()
                + " (" + valueFormatter.format(value) + ")";
        }

which displays label as:
name(value)

I need to display label in two lines
like:

name
value

Please david help me how to do it ? what changes i need to make ?
Thank you

I would insert a '\n' for the line break then make two further modifications:

(1) Find the code that draws the label and modify it to use a TextBlock;

(2) In the TextUtilities class, change the code that creates a TextBlock from a string so that it scans the string looking for line breaks.

Bear in mind that the pie chart labelling has been changed around quite a lot in the 0.9.17 release (which is due out soon). The new release doesn't do exactly what you want, but it does support label wrapping. You might want to grab the latest source files from CVS....
