Origin Version (OriginPro 7.5G SR6):
Operating System:Windows XP Professional
Hallo,
I have a little problem. I want to use Origin to draw a logarithm diagram. This works already, but I need on the y-axis a double logarithm scale. For example LogLog(D). D is a value from a sieve analysis, is the sum how much goes through the sieves. It is possible to do that in Origin?
Thank you for all your answers.
Best Regards
Matthias |

Hi Matthias,
Maybe you can add an additional column to the workbook where your data is, and use the Set Column Value tool to calculate log(log(D)). Then we can plot this new column against the original X values. Do you think it is okay?

Hi Deanna,
thanks for the immediate reply, but I need the original values of D. This means that only the y-axis must be double logarithm, not the values. It is possible to plot the LogLog(D) values with a defined y-axis? For example loglog(D)=0,2568, but in the diagram it displays at 56 %.Is this possible?
