Forcing x-axis ticks on a line chart

[grantnicholas]

Hi all. I'm having issues formatting the x-axis ticks on a line chart. I have the paid/licensed version of spire.
Lets say we have a linechart with values from 0 to 99 on the x axis.

Currently, powerpoint will display the xaxis values up to 99 and then stop. However, I would like a “pretty” x axis and would like to have the last tick mark be at 100.

I tried to do this by forcing the min and max value on the x axis (ie: the category axis) of the line chart.

Chart.PrimaryCategoryAxis.IsAutoMax = false
Chart.PrimaryCategoryAxis.IsAutoMin = false
Chart.PrimaryCategoryAxis.MinValue = 0
Chart.PrimaryCategoryAxis.MaxValue = 100

However, this did not work.

What is the proper way to force the xaxis tick values?

Thanks

Hello,

Thanks for your inquiry. I have observed the requirement and tried it, but I failed find any option even in PowerPoint to set the xaxis tick values, this kind of chart shouldn't support the feature. And you can try use XY chart.

Thanks for the quick response, that is what I figured but it was worth an ask.
