Read a given dataLabel's position on a slide

[majeed_s]

I'm guessing this will probably be impossible but wanted to check.

Is there a way to read a given datalabel's position (horizontal and vertical) on a slide?

I would like to add a textbox which is relative to the position of the given datalabel.

See before and after images attached.

Hi,

Thank you for your inquiry.
According to the picture you provided, I noticed that the data label is added by default in your chart. Sorry for the truth that our Spire.Presentation cannot get its coordinate position because there is no position information of default data label written into the document data. But if you manually move the location of data label, the position information would be written into the document, and you can use the code below to get the position of data label. If there is any question, please provide your input Powerpoint for further investigation.

Code: Select all

            IChart chart = ppt.Slides[0].Shapes[0] as IChart;
            ChartDataLabelCollection dataLabels1 = chart.Series[0].DataLabels;       
            ChartDataLabel label = dataLabels1[0];       
            float x=label.X;
            float y= label.Y;

Sincerely,

How can I add another shape according to the X and Y positions of a data label? Because these X and Y positions look like relative positions and I need absolute position or I need to add another shape relatively data label X and Y position.

Hi，

Thank you for your feedback.
Kindly note the X,Y of the data label is relative to the default label position, but the shape position is relative to the entire slide. Sorry there is no good way to add a shape according to the position of data label. If you have other question, please feel free to contact us.
