    I need to change the colors that make up the treemap graphic.

    Currently for each category/value of the chart, we have a specific color in RGB that we get from the database.

    How do we apply these colors to each chart category using Java ?

    In Excel, we do this as follows:

    In the chart, select a category manually, right click, fill, and choose a color (for each of the categories).

    // Create a new workbook
    Workbook workbook = new Workbook("License Key");
    IWorksheet worksheet = workbook.getWorksheets().get(0);
    		worksheet.getRange("A1:B"+finalPosition).setValue(Values); //define o alcance de células com dados na planilha
    //Create a treemap chart.
    IShape shape = worksheet.getShapes().addChart(ChartType.Treemap, 300, 20, 300, 200);
    //Set the parent data labels are displayed as banners.
    		//Modify chart title text.
    		shape.getChart().getChartTitle().setText("Alocação por Categoria");
    		shape.getChart().getChartTitle().delete(); //deleta as legendas do gráfico
    		shape.getChart().getLegend().delete(); //deleta o título do gráfico 
    		ISeries series1 = shape.getChart().getSeriesCollection().get(0);
