Chart title reverts to default

Kevin_Andras — Fri, 26 Apr 2024 20:36:34 GMT

I have C# code (pasted below) that creates a chart from a standalone table. This chart appears in the table of contents, with my specified chart title, as intended:

Then, when I open the chart to view it, the chart title reverts to a default value as if I'd created a chart from a table and did not specify a title.

I can open Chart Properties and it indicates the correct title:

Then, as soon as I click in the 'Chart title' text area, the chart updates with the correct title.

I would think that the chart title should appear as intended without having to perform these extra steps. Is this a bug? Is there another step my code has to perform?

Is it possible to open the chart programmatically? I don't see any obvious methods.

Thanks!!!

Hi @Kevin_Andras ,

Thanks for the question. When you configure the `CIMChartGeneralProperties`, please try adding a line to set the `UseAutomaticTitle` property to `false` (see documentation here) :

GeneralProperties = new CIMChartGeneralProperties { Title = tableTitle, UseAutomaticTitle = false }

This should prevent the title from being reset when the chart is opened in Pro, but please let me know if this does not solve the problem.

Take care,

Chris

Thank you for following up and thank you for bringing this to our attention! The code samples online will be updated to include a line that sets this property.
