Cannot make scale logarithmic for curve import wizard in Thermal Package Description

General
1

Error message appears when I try to change scale from Linear → Logarithmic. It says all values of X (or Y) must be positive (even though the values of X/Ymin and X/Ymax are already positive). Is this a bug?

So how do I change the scale to logarithmic?

Running Standalone on Windows 11.
Tried on version 4.9.4, version 4.8.9 and version 4.7.5.

Am I missing something?

The error message refers to the data points rather than the axis limits. Very likely your table contains the default data point [0, 0].

The wording of the error message was changed in PLECS 4.9 to make this clearer:

Logarithmic scale requires that all data points in the table have positive X values.
