Simplified LineChart - Just specify the dbLineChart and override default parameters with dbChartParams.

This example creates a csv file, save to scratch directory and then open it as csv datasource with 3 columns - F1, F2 and F3. F1 is the x-axis and F2, F3 are the two datasets. The dbLineChart will plot the two lines with default settings. A third line is created using user data.
