Why are my functions intefering with each other?

For an assignment I have been set I have needed to make two functions. The first function plots a set amount of figures, this number of figures is determined by the input of the function, e.g function(X,8) uses data X to plot 8 separate figures. The second function I have made plots a linear regression model for two columns of the data given to me. When I call these functions in a .m file it seems that the first function is including the figure from the second function as one of its own figures. For example if I call function(X,8) and the linear regression function in the same .m file, 8 figures are made with the last one being the linear regression model, when in reality I want 8 figures from data X as well as the linear regression figure. I hope I have explained my situation adequately, does anyone know why this is happening???

Are you creating a new figure for the linear regression model? If not then by default it will plot on the current figure which would, I assume, be the last of the 8 figures created by your first function.

You can explicitly number figures if you want too e.g.

figure(1);
figure(2);
...
figure(n);

although that also does not play well with two independent functions neither of which knows about the figure numbers created by the other so you are best off just creating a new figure as normal each time and keeping an array of the figure handles to use explicitly for any future instructions if required.
