Waterfall Chart: Failed to Rotate Labels on the Axis

Hi!

I tried to rotate labels on X-axis and Y-axis.
Code example:

var pres = new Presentation();
var pptChart = pres.Slides[0].Slide.Shapes.AddChart(ChartType.Waterfall, 0, 0, 700, 300);
pptChart.Axes.HorizontalAxis.TickLabelRotationAngle = 90;
pptChart.Axes.VerticalAxis.TickLabelRotationAngle = 90;

If I do the same with ChartType.ClusteredColumn - labels are rotated. But the waterfall axes aren’t reacted with the same actions.

ClusteredColumn.PNG (4.1 KB)
Waterfall.PNG (6.6 KB)

Is it somehow possible to rotate labels? Or is that a bug?

Thanks!

@ikyrieieva,
Thank you for the issue description.

I will check the problem you described and get back to you as soon as possible.

@ikyrieieva,
I’ve reproduced the problem with rotating labes on axes for waterfall charts and added a ticket with ID SLIDESNET-43132 to our issue tracking system. We apologize for any inconvenience. Our development team will investigate this case. You will be notified when the issue is resolved.

@ikyrieieva,
Our development team investigated the issue. There is the “Text direction” option for many charts, but it looks like Waterfall charts in PowerPoint documents do not provide ability to rotate axis labels in the same way. Unfortunately, we cannot also implement such a feature.

The issues you have found earlier (filed as SLIDESNET-43132) have been fixed in Aspose.Slides for .NET 22.6 (ZIP, MSI).
You can check all fixes on the Release Notes page.
You can also find the latest version of our library on the Product Download page.
