Hi Mariana,
It is possible to set the TextOrientation of the point labels to any directions say Up, Down, Left or Right. You need to set the DisplayText property of the series to true to make the TextOrientation to work.
You can also the change the angle of the point labels to any degree using Font''s Orientation property.
The following code illustrate this :
series1.Style.DisplayText=true;
series1.Style.TextOrientation=ChartTextOrientation.Up;
series1.Style.Font.Orientation=270;
series1.Style.Font.Size=9;
series1.Styles[0].Text="baseline";
The above code can also be achieved through PrepareStyle event.
Please try the attached sample which accommodates the above factors and helps you to display the point labels in vertical direction.
Thank you for your continued interest in Syncfusion products.
Regards,
Jaya
