Waterfall Chart: Failed to Rotate Value Labels on the Axis in C#

Aspose.Slides Product Family

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!

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.
