The syntax is set xtics <incr> | <start>, <incr> {,<end>}, so my command set xtics 10 is correct too, actually it is equivalent to your command set xtics 1.e6, 10. Neither your command nor my command produce meaningful x-axis tics. Only default setting of xtics (no command) produces correct tics on x-axis, even though the default settins should be eqivalent to: set xtics 10 or set xtics 1e6,10 or set xtics 1e6,1e8

I disagree. There should be no error message. On x-axis with logarithmic scaling and "set xtics 10" I expect major tic on every decimal-multiple value, and 8 minor tics between major tics (for 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-multiple). The range 1e6-1e9 contains 28 tics. The range 1e6-1e8 should contain 19 tics, and that is far from "1e+07" tics, therefore the message is nonsense.

André, thank you for your effort. At least you helped me to locate the cause. I will try to use v6.32 with my trick, because I can't hope for replacement of 25 computers because of problems with the single program. There are different programs used on these computers (Ansys, Siemens NX, PTC Creo), but none has problems with 3D graphics.

In v6.39, I am not able to use my trick to display panels (as I did in v6.32). Neither Light=off nor Axes=off help to display panels. http://people.tuke.sk/peter.gasparovic/pokus/xflr5_v639_opengl/ Even Clipping plane settings to the full right doesn't help. Yo can see in Clipboard 1 that with Light=on the surface is actually shaded in black color (different black color than of the background). Clipboards 6 and 7 shows clipped view from the right and left side of aeroplane. The clipping works as...

These old computers are in the university classroom. They have latest drivers for these chipsets. I have made screenshots They are self-explanatory - the changes of display are caused only by settings of "Light" and "Axes". http://people.tuke.sk/peter.gasparovic/pokus/xflr5_v632_opengl/
