Hi Pepe,

Did the information found in the other forum thread you referenced here not work for you?

Here's a snippet from the released docs that repeats that information:

Build 6.4.46
You can set specific colorcodes on the charts using @chartcolor:colorcode in the grouping text. The @chartcolor:colorcode will not show on the list.
Use @chartcolor:hide to hide a total from being used in a chart.

To be clear you caption the column to include the mentioned string. It will suppress that total from the chart, and the string will also be stripped out of the actual title displayed in the report grid.

For example: Total_Cost@chartcolor:hide will be captioned Total_Cost in the report grid, and that total will be excluded from the chart.
