What were you trying to do?
From within MATLAB 5.3, I was trying to force the graphics object 'axes'
to print in white--instead of the default (black), or in any other color.
What's wrong?
Normally, when something is plotted in MATLAB (using, say, the 'plot'
command), the graphics object 'axes' is generated in black. It is
usually possible to change this color by using 'set(gca)'. For example,
suppose I want to plot y=sin(x), and I type:
x=[0:0.01:1]*2*pi;
y=sin(x);
figure(1);
plot(x,y);
set(gca,'Box','off');
I want to print a hard copy of this plot, but I decide that I don't want the
y-axis to appear on the plot: just the x-axis and the plot. So I try:
set(gca,'YColor',[1 1 1]);
In the graphics window I see the y-axis color change from black to white.
(The color map has black as [0 0 0] and white as [1 1 1].) Things LOOK
like they should, but they do not PRINT like they should: the y-axis still
prints in black.
What should have happened:
When I print the graph (using 'print -P<printername>'), the plot should
have no markings along the y-axis: no tick marks, no tick labels, and no
axis line.
Incidentally, removing all tick marks (as in 'set(gca,'YTick',[]);') does
remove the ticks, but the axis still prints. Also, MATLAB will not allow
you to define a zero width for the axis itself
(i.e., 'set(gca,'LineWidth',0);') is not allowed.
Finally, I have noticed that this is NOT a problem in MATLAB version 5.1, but
only in versions 5.2 and 5.3.
