This Out-of-the-box reports issue can often be solved with a simple workaround.

1. Edit the Report

2. Go to the Chart Tab

3. Change the Chart Type to Tabular.

4. Save the report

5. Run the report.

6. Change the Chart Type back to the original type.


This solution applies to issues where the log file shows the following error:


[ChartingService] ChartingService.getChartData - Error during retrieving chart data.

java.lang.IllegalStateException: Value operation type must be COUNT when value axis is null



This error has been documented on TC 3.3. SP1, but may occur on other versions as well.
