Hello,

I'm using a TChart component, with a TColorGridSeries.

Values set to the chart are well displayed, but values displayed with the TColorGridSeries seem not to be ok.

In the printscreen from the zip, the yellow area has :
- a min set to 2.16 this is ok
- a max set to 2.6 but displayed more than 2.8

Do I have a bug or is there an issue. ?

Thierry

I think you aren't populating the series as it is expected.
The ColorGrid series draws as many cells as points you add to it.
You are adding two points with Z=2.6. That's where the cells bottom, not their top.
Also note Grids with a single row will take 1 as height.
