We have code producing a Line with Markers chart in PowerPoint. Each datapoint is meant to show 2 values along the y axis; an average value and peak value for a counter. The x axis would be the name of each item we are tracking the average and peak values of. 

Each datarow has 10 series. 4 of them are tracking values in different ranges of Average i.e. 0-25%, 26-29%, 70-89% and 90-100%. Then we have 4 more with the same ranges, but for Peak. Also, we have a Baseline series which we always set to 0 (this is purely for formatting of the actual chart; forcing a line to show at the bottom). Lastly, we have a series for the timestamp where the peak value occurred.

This code works fine if we have >= data rows including adding a row in the top for the header row showing the column names. If we have < 3 datarows, we get this exception when calling the IPresentation.Save(MemoryStream stream) method:

Exception: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
