Plotting multiple graphs in one figure

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??

[Ben Mitch]

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"?

[Salma]

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.

Answer 1

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

axes('NextPlot', 'add')

Answer 2

[Samer Husam]

try this:

curve 1: x1,y1

curve 2: x2,y2

curve 3: x3,y3

figure (1)  
plot(x1,y1,x2,y2,x3,y3)

Answer 3

[Igor]

maybe

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

[Walter Roberson]

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()
