Hello,

Thanks for your message.
The Tree map chart is a new feature in PowerPoint 2016, sorry at present our Spire.Presentation doesn't support it. We have added it into our upgrade list. Once it is done in the future, we will let you know at the first time. Thanks for your understanding.

Sincerely,

Hello,

Glad to inform that we just released Spire.Presentation Version:7.1 which supports creating "TreeMap" chart now, please download it and refer to the following sample code to test.

Code: Select all

Presentation ppt = new Presentation();
 IChart chart = ppt.Slides[0].Shapes.AppendChart(ChartType.TreeMap, new RectangleF(50, 50, 500, 400), false);
 chart.ChartData[0, 3].Text = "Series 1";
 string[,] categories = {{"Branch 1","Stem 1","Leaf 1"},{"Branch 1","Stem 1","Leaf 2"},{"Branch 1","Stem 1", "Leaf 3"},
                 {"Branch 1","Stem 2","Leaf 4"},{"Branch 1","Stem 2","Leaf 5"},{"Branch 1","Stem 2","Leaf 6"},{"Branch 1","Stem 2","Leaf 7"},
                 {"Branch 2","Stem 3","Leaf 8"},{"Branch 2","Stem 3","Leaf 9"},{"Branch 2","Stem 4","Leaf 10"},{"Branch 2","Stem 4","Leaf 11"},
                 {"Branch 2","Stem 5","Leaf 12"},{"Branch 3","Stem 5","Leaf 13"},{"Branch 3","Stem 6","Leaf 14"},{"Branch 3","Stem 6","Leaf 15"}};
 for (int i = 0; i < 15; i++)
 {
     for (int j = 0; j < 3; j++)
         chart.ChartData[i + 1, j].Text = categories[i, j];
 }
 double[] values = { 17, 23, 48, 22, 76, 54, 77, 26, 44, 63, 10, 15, 48, 15, 51 };
 for (int i = 0; i < values.Length; i++)
 {
     chart.ChartData[i + 1, 3].NumberValue = values[i];
 }
 chart.Series.SeriesLabel = chart.ChartData[0, 3, 0, 3];
 chart.Categories.CategoryLabels = chart.ChartData[1, 0, values.Length, 2];
 chart.Series[0].Values = chart.ChartData[1, 3, values.Length, 3];
 chart.Series[0].DataLabels.CategoryNameVisible = true;
 chart.Series[0].TreeMapLabelOption = TreeMapLabelOption.Banner;
 chart.ChartTitle.TextProperties.Text = "TreeMap";
 chart.HasLegend = true;
 chart.ChartLegend.Position = ChartLegendPositionType.Top;
 ppt.SaveToFile(outputFile, FileFormat.PPT);
