Is there an opportunity to add for each value in Graphview a bigger point? Like it's done in google analaytics for example: http://www.cutroni.com/blog/wp-content/uploads/2007/12/20071211-compre-two-metrics.png
I think it would make the data look way better ;-)
yes it's is possible since the new version GraphView 3.1.1.
From the Documentation:
You can set the flag to let the GraphView draw circles at the data points.
