    Default Making a pie chart


    I use JTable and JScrollpane in my java application, and I would like for every selected row in the scroll pane, the pie chart to be made for the values in % that the row contain.
    Can anybody help me please, with an example or a web site regarding this?

    Default Re: Making a pie chart

    You can search the web for Java pie charts. Doing one yourself should not be that hard if you are familiar with graphics and a little trig.
    Just draw a circle using drawOval method of the graphics context. Then simply draw a radius at each cumulative percentage of 2*PI radians around the circumference. The percentages in this case are the ones from your table. This assumes they add up to 100.
    You might also check out the Arc2D class.
