Can't set ChartDataLabelPosition to Left

[emremert]

Hi, I try to set the data label position of a chart. I try to set it to Left. But I get this error: "Position values: Center, InsideBase, InsideEnd, OutsideEnd".

Code: Select all

chart.Series[x].DataLabels.Position = (ChartDataLabelPosition)Enum.Parse(typeof(ChartDataLabelPosition), "Left", true);

'chart.Series[x].DataLabels.Position = (ChartDataLabelPosition)Enum.Parse(typeof(ChartDataLabelPosition), "Left", true)' threw an exception of type 'System.InvalidOperationException'
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2146233079

    Message: "Position values: Center, InsideBase, InsideEnd, OutsideEnd"
    Source: "Spire.Presentation"

Hi,

I tried with Spire.Presentation7.11.1 and got the same error.

I am using .NET 5.
Test environment: Windows 10 64-bit, Regiıon setting: USA.

I attached the example PPTX file.

I can't extract the code that uses your framework. It took too long. I also tried to create an example project.

What about sending a code snippet that modifies the chart data label's position in the attached PPTX file? So I can reproduce the problem and record a video.

Thanks

Hello,

Thanks for your feedback.
I have some information to tell you:
1) Do you want to achieve the effect of the screenshot1 below? If so, you need to use the following code to achieve it.

Code: Select all

chart.ChartLegend.Position = ChartLegendPositionType.Left;

2) The below code you provided is that setting the position of data label, and you only set these values to it(Center、Inside End、Inside Base、Outside End). As shown in the screenshot2 below. And in the ppt file (chartDataLabelPosition.pptx), I didn’t find the data label.

Code: Select all

chart.Series[1].DataLabels.Position = (ChartDataLabelPosition)Enum.Parse(typeof(ChartDataLabelPosition), "Left", true);

If these message doesn’t help you, please offer the result PPT document you excepted to help us provide solution for you. Thanks for your assistance in advance.
