I want to create Weibull paper in Excel. The problem is the labelling
at the Y-axis.

I want to label probabilities (between 0.1 and 99.9%), but want to plot
the transformed logaritmic data; calculated out of the probability via
ln(ln(1/(1-p)))

X P (probabiliy, label) Y (transformed data; to be plotted)
155 97,89% 1,350040182
325 97,61% 1,317875745
500 97,34% 1,288316244
525 97,07% 1,26088904

How can I do this either with or without VBA?
....

Chart both P and Y but use two y-axes with P on the left y-axis, then
set the markers and the lines for the P series to nothing. The P series
won't appear, but its y-axis will. If you don't want to see the Y
series's y-axis labels, disable all its tick marks and set it label
number format to ;;;. If you change the lower and upper bounds for P's
y-axis, you'll need to make corresponding changes to Y's y-axis bounds.
