[jCharts-users] Problem generating Bar Charts from Database

[Campano, T. <Tro...@Li...>]

Hello,=20

I'm trying to generate a bar graph from a database.

I define my labels and data like this:

=20

                     String[] xAxisLabels =3D new =
String[amount_of_rows];

                     double[][] data        =3D new
double[amount_of_rows][amount_of_rows];

=20

=20

...and I scroll through my JDBC ResultSet like this:

=20

                                           xAxisLabels[i] =3D
rs.getString("engine_vrsn_nme").toLowerCase();

                                  data[i][i]  =3D
rs.getDouble("version_count");

=20

=20

...but I get this error:

org.jCharts.chartData.ChartDataException: There is not an one to one
mapping of 'legend labels' to 'data sets'.

=20

Any ideas?

Thank you!
