FlexReport allows you to add data to the charts without binding the charts to a data source. You can plot series on chart and display it by setting an array of X and Y values directly in unbound mode. Let us add an unbound 2D chart by performing the following steps:

1. In the C1FlexReportDesigner application, create a new report by navigating through the C1FlexReport wizard or open an existing report definition.
2. Add Chart field to the Detail section.
   Note: To add Legacy Chart field to your report, you need to add it to the INSERT tab. In order to do that, go to File|Options in the designer and select Show "Legacy Chart" button on the INSERT tab.
3. In Properties window, expand ChartGroups|Group0|ChartType and select a type of chart from the ChartType dropdown. In our case, we have selected Bar chart type.
4. Navigate to ChartGroups|Group0|ChartData and click the ellipsis button next to UnboundSeriesList property.
5. In the ChartUnboundDataSeries Collection Editor, add any number of series you want to plot in chart. Here, we have added two series.
6. Select one of the series and click the ellipsis button next to SeriesData property.
7. In the editor for series data, enter your data.
8. Click OK to close the editors.
9. Click the Preview button to switch to Preview mode to view the report.
   

For 3D unbound chart, perform the following steps:

1. Add Chart field to the Detail section.
2. In Properties window, expand ChartGroups|Group0|ChartType and select a type of chart from the ChartType dropdown. In our case, we have selected Surface chart type.
3. Navigate to ChartGroups|Group0|ChartData|UnboundData|GridSet.
4. Set the ColumnCount and RowCount properties to the desired value, if required. In our case, both ColumnCount and RowCount properties are set to 0.
5. Click the ellipsis button next to the GridData property.
6. In Single Array Editor, enter data and close it.
7. Click the Preview button to switch to Preview mode to view the report.
