Plotting Multiple Collections of Data Series on the Same Graph

I am trying to plot 3 phase voltages and currents on the same xy scatter plot by using VBA. The 3 currents should have their own Y axis, and the 3 voltages should have their own Y axis. Both the collections need to be plotted on the same graph by sharing the X axis. I am able to get all 3 currents on their own graph, and I can plot the voltages on their own graph, but how can I get them together on the same graph?? I have manipulated Excel to where the X axis (time) information is in column A, currents are in columns B-D, and voltages are in columns E-G. Please see the attached document for an example of what I am trying to do. Thanks
