I am making two plots in a for loop one after an other. When the loop goes for the next i, I need to hold on the plot becaue I want to plot x1 and y1 of the i=1 to i=n in one axis but because there is an other plot after it, I do not know how to do that so that x1 and y1 of i=1 to n are plotted in one figure and x2 and y2 of i=1 to n are plotted in an nother figure.
For i=1:n
do some calc.
figure
plot(x1,y1)
if I hold on here, the next figure may have be plotted in the first one. But I need to have figures of i=1 to n plotted in one axis.
figure
plot(x2,y2)
end

IF you want to plot in different figure
figure(1)
figure(2)

Try changing the plot target by referring to the link below.

You just need to move the figure command or you’ll get two new figure windows. This would be something like:
figure
for i=1:n
do some calc.
plot(x1,y1)
hold on
plot(x2,y2)
end
or alternatively put both of the plotting commands into one:
plot(x1,y1,x2,y2)

@ME thanks but it was not answer to my question. I said in the question, I want to have TWO plots one is for x1 and y1 and the other one is for x2 and y2. For x1 and y1 of ALL i from 1 to n I want to plot x1 and y1 on the same figure and for ALL i from 1 to n I want to plot x2 and y2 on an other figure.

Apologies, I think I see what you mean now. That just shows I shouldn't answer questions before a morning coffee!
I think this should do what you want:
for i=1:n
do some calc.
figure(1); hold on;
plot(x1,y1)
figure(2); hold on;
plot(x2,y2)
end
