Tagvalue in Labels

Post by BPJ »

Hi.
In Chart > edit series you can make labeltexts. Is it possible to insert a tagvalue?
For example: I want to label a value with the corresponding hour.

Thanks

No , you can not dynamically change the series labels. You can create your own legend by using Text boxes and then using code to assign them a value. You can use a small rectangle the same color as the series to indicate which label goes with which series.

Code to set Text box:
this.Text1.Text = "MyText " + Globals.Tags.Tag1.Value.ToString();

I have a similar problem to this, I'm dynamically assigning a variantValue array (of ints) to a series' y values successfully but when I try to assign a variantValue array of (datetime's) to the series' xvalues, the terminal crashes to the T7A boot screen. Is this possible to do or will I have to use labels as above?

I'd like to be able to use the same chart for 7 days, 31 days, 12 months, etc. Making labels for all these possibilities would be extremely messy!

Since submitting the above post, I've almost managed to solve my problem by assigning a new LabelsList containing the dates to "Series[0].Labels". This works but unfortunately also overwrites the Y-Axis value at the top of each bar with the date as shown in the attachment.

Does anyone know if this is possible to fix or even remove these labels from the top of the bars?
