Hi,
As usual, there are several solutions, depending on the amount of time
you are wiiling to spend on them.
1-As the histogram plot contains only one graph, there is no reason to
insist on putting your information on a legend: title("Real
distribution");plot(Xreal, Yreal) would do the trick.
2-If the rather silly "line 1" inside the frame pisses you, you can
issue the command "gset nokey", immediately before and "gset key"
immediately after.
3-If you are as impulsive and sloppy as me, you can modify the function
bar.m, by putting the above mentioned commands before/after the line
plot (tmp_xb, tmp_yb); or modify it to be plot (tmp_xb, tmp_yb, ";;");
4-A slightly better way is to replace this line by:
plot (tmp_xb, tmp_yb, ";;"); # originally plot (tmp_xb, tmp_yb); .
modified on a rainy afternoon, A.R.
5-The proper thing to do is to copy hist.m and bar.m to the directory
where you store your own mfiles, modify mbar.m like above and rename it
candybar.m. Then you modify your copy of hist.m to call candibar instead
of bar, and rename it to something handy and intuitive, which you will
call instead of hist.
6-The alter4native to 5, if you think that your problem is shared by
many others is to suggest a permanent change in bar.m by submiting a bug
report...
Good luck, Avraham
PS Suggestions tested on octave-2.1.50, on a debian-3r1 stable release.
