Move labels for negative values on top of the chart

[ipeadmin]

Hi Team,

Could you tell me if there is a way to move all labels above the chart bars (column chart) - by default when label position is set to “Outside End” labels will be shown below the bars in the chart - please see attached image.

You can move them manually - is there a way to move labels with Aspose, to get the result as on the attached image?

@ipeadmin,

I have observed your requirements and like to share that you can set the label position as fraction of chart width and height. You can set Label’s X and Y position between -1 to 1. The value 0,0 will correspond to default label position. Please observe the following sample code and use it as per your convenience on your end.

public static void TestLabelPosition()
{
    Presentation pres = new Presentation();

    IChart chart =pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn,20,20,400,400);
    chart.ChartData.Series[0].Labels.DefaultDataLabelFormat.ShowValue = true;
         
    //Top right position
    chart.ChartData.Series[0].DataPoints[0].Label.X =-1;
    chart.ChartData.Series[0].DataPoints[0].Label.Y = -1;

    //Actual Label position on desired label
    chart.ChartData.Series[0].DataPoints[1].Label.X = 0;
    chart.ChartData.Series[0].DataPoints[1].Label.Y = 0;

    //Bottom Right
    chart.ChartData.Series[0].DataPoints[2].Label.X = 1;
    chart.ChartData.Series[0].DataPoints[2].Label.Y = 1;

    pres.Save(@"C:\Aspose Data\LabelPostions2.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

}

Many Thanks,
