xlim
to adjust the X axis limits of
a plot. The various syntaxes are
xlim xlim([lo,hi]) xlim('auto') xlim('manual') xlim('mode') xlim(handle,...)
The first form (without arguments), returns a 2-vector containing the
current limits. The second form sets the limits on the plot to [lo,hi]
.
The third and fourth form set the mode for the limit to auto
and manual
respectively. In auto
mode, FreeMat chooses the range for the axis
automatically. The xlim('mode')
form returns the current mode for the axis
(either 'auto'
or 'manual'
). Finally, you can specify the handle of an
axis to manipulate instead of using the current one.
As an additional feature, you can now specify inf
for a limit, and
FreeMat will take that limit from the automatic set. So, for example
xlim([10,inf])
will set the minimum for the x axis, but use the
automatic value for the maximum.
--> x = linspace(-1,1); --> y = sin(2*pi*x); --> plot(x,y,'r-'); --> xlim % what are the current limits? ans = -1 1which results in
Next, we zoom in on the plot using the xlim
function
--> plot(x,y,'r-') --> xlim([-0.2,0.2])which results in
To demonstrate the infinite limits feature. Consider the following
--> plot(x,y,'r-'); --> xlim([0,inf])which results in
