Null series and category labels for chart

[boncyrus]

Hi,

I'm using Spire.Presentation 8.3.2. Is there a way for us to create chars with null category and series labels?

Thanks!

[boncyrus]

I tried populating by assigning empty string but I don't think it's working

Code: Select all

chart.ChartData[0, 1].Text = "";
chart.Categories.CategoryLabels = chart.ChartData["A2", "A2"];


can you please guide on how to create charts with null series and category

thankss!

Hi,

Thanks for your feedback.
You can refer to the following code to set the category label to be null.

Code: Select all

//Hide axis
chart.PrimaryCategoryAxis.IsVisible = false;


As for setting series labels, could you provide a screenshot to show your desired effect? Thanks in advance.

We don't want to hide the axis by using the `chart.PrimaryCategoryAxis.IsVisible` property, we can't modify any of the chart properties, we simply want to add a empty string to the cell. It's possible to do this in PowerPoint.

Hi,

Thanks for your feedback.
I did notice that the chart didn't update accordingly after setting " chart.ChartData[1, 0].Text = """. I have logged this issue into our tracking system with the ticket SPIREPPT-2243, our Dev team will do further investigation and fixing. Once there is any update, we will keep you informed. Sorry for the inconvenience caused.
