Simplified AreaChart - Just specify the dbLineChart and override default parameters with dbChartParams. This example creates a csv file with one label and 2 datasets, save to scratch directory and then open it as csv datasource with 3 columns - F1, F2 and F3. F1 is the label-axis and F2, F3 are the two datasets. The dbAreaChart will plot the two areas with default settings. A third line is created manually in dbChartParams with it's own settings.
