Cannot Remove Legend Key from Data Label

[Stecya]

Hi,

I'm adding some custom DataLabels to my series , and all of them shows Legend key (Marker by default).
I tried to remove it but with no success

Code: Select all

ChartDataLabel.LegendKeyVisible

and

Code: Select all

ChartSeriesDataFormat.LegendKeyVisible

are not doing a thing.

See code snippet and attached screenshot. There 2 markers for every point there : one from series another from datalabel, I want the 2nd one to be gone.

Code: Select all

        static void Main(string[] args)
        {

            var presentation = new Presentation();
            var slide = presentation.Slides[0];

            var chart = slide.Shapes.AppendChart(ChartType.ScatterStraightLinesAndMarkers, new RectangleF(50, 50, 500, 500), false);

            int count = 5;

            chart.Series.SeriesLabel = chart.ChartData[0, 0, 0, count - 1];
            var pointCount = 1;
            for (int i = 0; i < count; i++)
            {
                chart.ChartData[0, i].Value = "Series" + i;

                for (var j = 0; j < pointCount; j++)
                {
                    chart.ChartData[j + 1, i].Value = i;
                    chart.ChartData[j + 1, count + i].Value = i + j + count;
                }

                chart.Series[i].YValues = chart.ChartData[1, i, pointCount, i];
                chart.Series[i].XValues = chart.ChartData[1, count + i, pointCount, count + i];

                var cd = chart.Series[i].DataLabels.Add();
                cd.ID = 0;
                cd.LegendKeyVisible = false;
                cd.BubbleSizeVisible = false;
                cd.CategoryNameVisible = false;
                cd.LabelValueVisible = false;
                cd.TextFrame.Paragraphs[0].Text = $"Marker";

                chart.Series[i].DataLabels.LegendKeyVisible = false;
                chart.Series[i].DataLabels.LeaderLinesVisible = true;
            }

            presentation.SaveToFile("D://test.pptx", FileFormat.Pptx2013);
            Process.Start("D://test.pptx");

        }

Dear Stecya,

Thanks for your inquiry.
There was something wrong when adding the custom data label, and it caused two markers. Please set cd.LabelValueVisible as "true" firstly, and then set your custom data label. Finally, there will be only one marker. Code snippet:

Code: Select all

                    var cd = chart.Series[i].DataLabels.Add();
                    cd.ID = 0;
                    cd.LabelValueVisible = true;
                    cd.TextFrame.Paragraphs[0].Text = "Marker";

If there is any question, welcome to get it back to us.
