Re-reading bug #61945 (for which the behavior of `newplot` was changed), it's probably not correct to change the "currentaxes" here either. Instead, it would probably be better if `__next_line_color__.m` and Co. accepted an axes argument instead of always referring to `gca`...

Thanks for your bug report. (It should probably better be on the bug tracker. But I don't know how to move it from this patch tracker to there now.)

I can confirm this bug. It is probably caused by the fact that "newplot" changed the "currentaxes" in previous versions. But it no longer does so in Octave 7. The function "stairs" still relies on the old behavior.

The attached patch should fix that.

It is probably worth checking all functions that use "newplot" whether they still assume the old behavior, too.

(file #53125)

stairs ignores first arg: axes handle

H1 = subplot(2,1,1);
H2 = subplot(2,1,2);
stairs(H1, 1:5,1:5, 'b')
stairs(H2, 1:5,1:5, 'r')

both draw commands goes into last axes handle

This does not happen with plot(H, ...)
