I can't see points data, only blank gap. I don't know weather is my browsers fault or I did something wrong when I was writing previous post, so here they are:

 XvalsCf := [0, 5, 10, 25, 50, 100, 140, 200, 250, 300, 400];


 YvalsCf := [0.5e-2, 0.4e-2, 0.3e-2, 0.26e-2, 0.23e-2, 0.21e-2, 0.2e-2, 0.19e-2, 0.18e-2, 0.175e-2, 0.15e-2];

Best regards!

But what if this table has 1000 rows? How to automate this process? And how to do this when we have data in a spreadsheet?

Best regards!
