Mschart... Graphing two lines on the same chart

I am trying to graph to sets of data on the same chart. These two lines fall within the same range, however set two has many more data points than data set one (greater resolution). I want to be able to show both graphs with their respective data points on one graph. Is that possible? In other words, how can I manipulate the row property to show different data sets with different row counts?

You can define two series of data for your two row sets, then plot one series on the primary axis, the other series on the secondary axis.
ie. you would have an x axis along the bottom, a y axis on the left vertical and a z axis on the right vertical....
If you search the chart help file for "secondary axis" you should find out the exact way to do it.
