Hello everyone!
I have a problem with drawing a plot on an axes. For example I have code like this:
function DrawSmth
FigurePos=[60 80 1820 890];
figure('Units', 'pixels', 'Position', FigurePos,'Color', 'w', 'Tag', 'Fig', 'MenuBar', 'none');
AxesPos=[650 90 300 400];
axes(gcf, 'Units', 'pixels', 'Position', AxesPos, 'Tag', 'Graphic','Color', [1 0 0]);
x=0:0.01:2;
y=sin(x);
plot(gca,x,y);
zoom on
On a picture you can see what I get when run the code.
I get this even when I try the examples in MatlabDocumentation like this:
figure
tab1 = uitab('Title','Tab1');
ax1 = axes(tab1);
plot(ax1,1:10)
tab2 = uitab('Title','Tab2');
ax2 = axes(tab2);
surf(ax2,peaks)
If anyone can help,I'l appreciate this.
Update.
It does'nt show even this:
x=0:0.001:2*pi;
y=sin(x);
plot(x,y)
Still the empty figure window.
