Dear Eugene,

There should be no problem in the Multiwfn code. For example, the scatter map and isosurface map for phenol dimer look very normal.

Your scatter map is not necessarily wrong. In the interaction region the blue is fairly deep, implying that the rho in that region is relatively large. If you decrease the lower limit of X-axis of the scatter map, possibly the peak can be viewed more sufficiently.

Best regards,

Tian

Problem with plotting 2D IGMH plot

Dear Prof Lu,

In my research, I often use IGMH to analyze and visualize non-covalent interactions, both isosurface and 2D plot delta-g_inter vs. sign(lambda2)rho. However, not long ago I encountered a problem in building a 2D plot. In my opinion, the 2D IGMH plot looks wrong, whereas the IGMH blue isosurface looks great. I tested different versions of Multiwfn, however, I got the same result. I have previously used IGMH to analyze a similar interaction. No such problems were observed. Unfortunately, I can't understand why the 2D IGMH plot looks like this for a given interaction.
I would be very grateful to you for any comments.
