About

Gets or sets the list of chart types which will appear in the Chart Type dropdown on the Charts tab. This is primarily used to disable chart types. The Visualization chart type will appear based on the Visualizations feature.

Default Value: {Trend, Pie, Plot, Bar, Funnel}

NOTE: Depending on the charting engine, the Plot chart may not exist. Plot does not exist in HTMLCharts, but does exist in DundasCharts.

Note: To remove Visualizations from the drop down list you can add this sample below as Visualizations are appended based on the license key after the chart collection is complete.

 public override ReportSet LoadReportSet(ReportInfo reportinfo, DatabaseSchema schema)
        {
            AdHocSettings.Charts.Remove("Visualization");
            return base.LoadReportSet(reportinfo, schema);
        }

    //Check to see if we've already initialized.
