Hello, we have purchased license.
We use Line chart with N series, and in some series values by some categories may be empty.
For example:
var shape = builder.InsertChart(ChartType.Line, height, width);
var chart = shape.Chart;
chart.Series.Add("series 1",
new[] { "cat1", "cat2", "cat3", "cat4", "cat5"},
new[] { 5, 5, 5, 5, 5 });
chart.Series.Add("series 2",
new[] { "cat1", "cat2", "cat3", "cat4", "cat5"},
new[] { 1, null, 5, null, 7 });
But we cannot have null values in series, since ChartSeriesCollection.Add method signature is Add(string seriesName, string[] categories, double[] values);
However, in Microsoft Word we can have empty (null) values in this case.
How can we achieve this?
