Re: Example of chage of snapshot of image demo before and after Nov. 06 [was Side effect of change src/wxterminal/gp_cairo.c ...]

Hello

OK I see.

Default windows size of windows terminal is very large,
(In my case GraphSize=920 725)
I have change Graph size to my favor.

Considering the above, appearance of the graph is to be optimized by the user.

BTW, it is interesting that the appearance of same plot is different for each other in default size on
Windows or Linux.

Regards

Tatsuro
