Thread Subject: Changing Legend transparency

When I first add a legend, it has a black border and
it is non-transparent. If I execute "legend boxoff",
the black border goes away AND the legend becomes
transparent. How do I turn off the border and keep
the legend non-transparent?

You can right-click the legend frame and choose the "properities" to
edit it.

Randy,

I take it that you just want to hide the box around the legend and keep the
background colour:

to do this I would set the edge colour of the legend to match the background
color. See below

Plot(x,y); % plot data
h=legend('test'); %create lengend
set(h,'EdgeColor',[1 1 1]); %set the edge colour of the legend to white
which should be the default of the background

Hi SC,

Thank you for your response.

There is no such 'EdgeColor' property. Are we using the same version?
I'm using 6.1.0.450 (R12.1).

Hi Dorothy,

Thanks for your response.

There are two problems:

  1. I can't see a property for the legend border
  2. I need to do this programmatically rather than interactively.

Randy,

I'm using 2006a and b.

I'll load up my r12 and see if I can get that to work

Sorry Randy for building your hopes up, but I can't do it in release 12.1

They have added more functionality so I would suggest upgrading to a newer
version if you can

Hi,

here are all the properties you need :

x = -pi:pi/20:pi;
plot(x,cos(x),'-ro',x,sin(x),'-.b')
h = legend('cos','sin',2);

set(h,'box','on', ...
'color','y', ...
'ycolor','m', ...
'xcolor','b', ...
'visible','on')

Hi Jerome,

Thanks for that! A variation on your idea works for
the screen:

set((hl,'color','w','xcolor','w','ycolor','w');

However, when I print (print('file.eps','-depsc2'))
it's back to black borders. Arghh! How to get
no borders when PRINTING?!???

Hi,

read this :

 <http://www.mathworks.com/support/solutions/data/1-16FH1.html>

You have to set the INVERTHARDCOPY property of the figure to OFF

Actually I did not. I simply followed the instructions for
6.x. (Apparently it was a matter of setting the xcolor and ycolor not
to white but to the actual figure background color, which was [0.8 0.8
0.8] on my system. These then get converted to white when printing when
INVERTHARDCOpY is on.)

Thanks for your help, Jerome!
