Hi than you for reply,

I think you need to graft the lengths that are coming into the evaluate lengths component.  Right now I think it's trying to match each length up with individual lines.  If you graft the length input to "Evaluate Lengths" I think you'll be all right.

Can you send me the picture of grasshoper sample?

thank you

Here's a pretty straight forward example...if i understand your question properly.

1- generate your list of curves, (this example starts with them already generated and contained in the curve parameter.

2- reparamaterize curves (making domain of line 0 to 1)

3- divide the curves, (this gives us the the t value of each point on the line

4- feed those t values into a graph mapper, (graph type of your choice, below uses "power")

5- feed manipulated t values from graph mapper into evaluate curve.

6- flip matrix of points if you want to draw some lines through them.

As you can see below, it's precisely the same as your original grasshopper sample with the length input to "Evaluate Lengths" grafted.  The VB components have a warning in mine because the VB code is referencing the now obsolute MRhinoDoc instead of RhinoCommon, but it all works the same.
