Section: Handle-Based Graphics
subplot(row,col,num)
which either activates subplot number num
, or
sets up a subplot grid of size row x col
, and then
activates num
. You can also set up subplots that cover multiple
grid elements
subplot(row,col,[vec])
where vec
is a set of indexes covered by the new subplot.
Finally, as a shortcut, you can specify a string with three
components
subplot('mnp')
or using the alternate notation
subplot mnp
where m
is the number of rows, n
is the number of columns
and p
is the index. You can also specify the location of the
subplot explicitly using the syntax
subplot('position',[left bottom width height])
subplot
to set up a 2 x 2
grid of plots
--> t = linspace(-pi,pi); --> subplot(2,2,1) --> plot(t,cos(t).*exp(-2*t)); --> subplot(2,2,2); --> plot(t,cos(t*2).*exp(-2*t)); --> subplot(2,2,3); --> plot(t,cos(t*3).*exp(-2*t)); --> subplot(2,2,4); --> plot(t,cos(t*4).*exp(-2*t)); --> quit
Here we use the second form of subplot
to generate one subplot
that is twice as large.
--> t = linspace(-pi,pi); --> subplot(2,2,[1,2]) --> plot(t,cos(t).*exp(-2*t)); --> subplot(2,2,3); --> plot(t,cos(t*3).*exp(-2*t)); --> subplot(2,2,4); --> plot(t,cos(t*4).*exp(-2*t)); --> quit
Note that the subplots can contain any handle graphics objects, not only simple plots.
--> t=0:(2*pi/100):(2*pi); --> x=cos(t*2).*(2+sin(t*3)*.3); --> y=sin(t*2).*(2+sin(t*3)*.3); --> z=cos(t*3)*.3; --> subplot(2,2,1) --> plot(t,x); --> subplot(2,2,2); --> plot(t,y); --> subplot(2,2,3); --> plot(t,z); --> subplot(2,2,4); --> tubeplot(x,y,z,0.14*sin(t*5)+.29,t,10) --> axis equal --> view(3) --> quit
