Plotting multiple graphs in one figure

Asked by Salma
on 27 May 2011
I want to put 3 curves in one graph but i couldn't use the hold on function because for each curve i run several times to get the values i want so any idea how to do it without the hold on function??

Hi Salma - it's not clear what the problem is. What do you mean by "i run several times"? Run what? Why does that obstruct the use of "hold on"?

i run the code several times because the input is random
Please show the structure of your code. It is not clear why "hold on" would not work for you.

If you want to avoid "hold on" for any reasons (which I cannot understand), try this initially:
axes('NextPlot', 'add')

try this:
curve 1: x1,y1
curve 2: x2,y2
curve 3: x3,y3
figure (1)
plot(x1,y1,x2,y2,x3,y3)

maybe
plot(gca,x1,y1)
plot(gca,x2,y2)

Igor, under the default settings, the second plot would overwrite the first. Using "hold" or setting NextPlot are necessary to prevent that.

If you are not specifically creating a new figure each time, then you could switch to using line() instead of plot()
