Is it possible to show two series with different number of datapoints on the same chart. For instance, I want to have a column graph with 12-24 columns that has a line graph showing a limit drawn with just 2 datapoints. I would also like to draw a trend line on a line graph with hundreds of datapoints by defining just the starting and ending points of the trend line.

Also have you evaluated the xamDataChart? xamDataChart has built in support for many different trendline types by simply selecting which type of trendline you want to accompany a series.
