How it Works

barchart.BarChartGerador

Creates the BarChart

barchart.PendenciaBarRenderer

Extends BarRenderer3D making it possible to change Bar Colors the way you want.

barchart.PendenciaData

Carries all the attributes necessary for every row in the chart. It's a POJO.

barchart.PendenciaDataset

Handles which bars should be created for each PendenciaData. Usually a chart has 1 bar for each Item, but this one, for example, has 2.

barchart.PendenciaURLGenerator

Lets you customize all the links inside the chart image

index.jsp

<%
    PendenciaDataset dataset = BarChartGerador.mockCriarDataset();
    // generates the <MAP> in the JSP for all the links inside the chart image
    BarChartGerador grafico = new BarChartGerador("JFreeChart - Bar Chart Example", dataset, session, new PrintWriter(out));
    String filename = grafico.getFilename();
    String graficoGeradoURL = request.getContextPath() + "/servlet/DisplayChart?filename=" + filename;
%>
<img src="<%= graficoGeradoURL %>" border=0 usemap="#<%= filename %>">
