Sometimes when we display values in a bar chart with a datatable, it would be nice to show a different item in the datatable than that of the y value. For instance, we might have a series where anything less than zero is an invalid value. It would be nice to have no bar in the chart, and the string "Invalid" in the the datatable for that index. Is there a way to do this or something similar?

Thanks!

Hello AIDev,

If you have a datatable you could modify your data as you want, changing values of datatable according the Chart. On the other hand, if you don't want appear null values (or 0 values) in your chart you can put bar.Color = Color.Transparent this.


I hope will helps,

Thanks.

Hi Sandra,

I am sorry as I was a little vague with my question. I was referring to the TChart Datatable Tool, not a generic datatable.

If you were referring to the datatable tool, how do I change a value in the table to string?

Thanks!

Hello AIDev,

I was referring to the datatable generic. I am sorry but is not possible change values to tChart dataTable Tool. But, I recomend to use Chart Grid because this allows change values of table. You can send an example if you see TeeChartNet Demo concretly All Features\Welcome !\Components\Chart Grid.


I hope that will helps.

Thanks,

Hi Sandra,

unfortunately the Chart Grid is not the representation we need. We need to show the data aligned with the graph.

Hello AIDev,

I have added your propost of Datatable Tool on our to be considered for inclusion in future releases 4. Number of feature request is [TF02014466].
