[Scilab-users] Plot with two different y-axis as one plot

[Frieder Nikolaisen]

Dear Mr. Gougeon´,


my mail was blocked, because I had a 150kB Picture attached...

I did you the plotyyy demo for my Programm. It's a nice result. I still 
have a Trouble by putting the plots on each other: I did build a user 
Interface with the guibuilder tool 3.0. There I did use the Axes tool to 
have my plotyyy in the same window. But only my ploty ist plotted in the 
White area and the other two plots are in the entire window. How to 
solve this?


I did attach a plot, now 20kB, of a pump from an old exam. The plot 
does provide SI dimensions as well as US ones. Thats why there are three 
x-axis and two y-axis.

Best regards
Frieder Nikolaisen
