I think the length of the probe lines are not constant. If you place the meter in the lower left you can drag a probe to the upper right (and beyond). The length of the line seems longer to me.
I think everything in hat Java app looks doable in C2. I think you are going to need to use something like this plugin to accomplish those lines.
I haven't played around with this plugin too much, but it does have bezier curves, which is what I think you will need for those curved probe lines.
