We too are very much in need of this feature, to allow us to specify a color for each series in chart with Aspose.Words. (We are using the .NET version of Aspose.Words with C#).
In our case, we wish to chart nine sets of data points, which subdivide into three categories. We want to show that each of the categories behaves in a similar way. In order to do this, we want to use shades of blue for the three sets from category 1, shades of green for the three sets from category 2, and shades of red for the three sets from category 3. Thus, the visual effect will be such that lines belonging to a single category will be related via their color.
