failure in reversed xdir or ydir axes

[Eric Chassande-Mottin]

hi,

when invoking set to get reversed axes, the new axes labels overlap
with old ones and the axes does not get reversed effectively.

when running
plot(1:10)
set(gca(),"ydir","reverse")
or
plot(1:10)
set(axes,"ydir","reverse");
I get the following figure
test.png

is that a known issue?
is there a simple fix?

thanks,
eric

I click "post message" too fast

plot(1:10)
set(gca(),"ydir","reverse")
does work
while
plot(1:10)
set(axes,"ydir","reverse");
does not.

Eric / others,

I had  hoped to look at this sooner, but the display on my notebook has died.

If no one gets to it, I'll be functional again in a week or two.

Is that really a bug?

set(axes,"ydir","reverse");

As I understand it, the "axes" call creates a new axes object and
inserts it into the current figure, "set" then sets the attribute,
which works, but you now have two axes in the figure, but only one of
them with ydir reversed. That's what I see.

that makes sense. I thought that axes was returning an handle
to the current axes.

sorry for the false alarm, eric.

Jaroslav, you are correct. I compared 3.0.5, and 3.2.0 to Matlab 2007b (I'm still able to run the released versions). All gave the same result.

Eric to get what you had expected, try ...

    set (gca, "ydir", "reverse")
