i'm glad it worked
my changes were simple:
your original code is below - all i did was change the x value of the NetInGraph meter to 85, and adjusted the h so it was the same height as the histogram.
then i shifted NetInHist 85 pixels across, and 1 up, added an autoscale, and adjusted the width so it fits in with the other meters.
finally, i repeated for the NetOut graphs.
you can learn more in the new rainmeter help file - have fun customising!
