Assuming you have just opened MATLAB, your axes are first created when you do "hold on" (which isn't really the best way to create axes, since it's not obvious to people who read your code).

Possible duplicate of Plotting graph using for loop in MatLab – Cris Luengo Dec 2 '18 at 6:14 @Cris I do not think this is a duplicate. How do I hold plots from a for loop?. hold on for double plots in one loop. The task is to read three variables from files in FOR loop, read variables, plot figure (1) (var1 vs var2), hold the plot, save it; plot figure (2) (var1 vs Var3) hold the plot save it. They are located in the for loop, but I had deleted them accidently with my comments from my code when I pasted it into my previous comment. I have the hold on command in my code, but I still get only one point on my plot. Learn more about for loops, hold on, hold all MATLAB I have specified the production of a graph within a 'for' loop but when I run the code, only the graph for the last run of the loop is displayed. I am using MATLAB to plot a graph. They are located in the for loop, but I had deleted them accidently with my comments from my code when I pasted it into my previous comment. Not sure if the plot is expected to look like this but using an additional outer for-loop to index through the values of p and run the function multiple times can be used to achieve this result. I don't want to store all the vectors for each loop due to storage constraints and instead, the values in the vector are overwritten with each run of the loop. Learn more about matlab, plot, stop, switch, case, guide MATLAB. Once Matlab reads the end statement, it will execute and repeat the loop.

There are a few lines where I set up the dummy variables u and w, which are functions of x. Learn more about plotting MATLAB. Although it will be some microseconds only, I prefer: hAxes = axes( 'NextPlot' , 'add' ); % See source of: hold Later, when you use subplot, it actually deletes these axes and replaces them. I made a transition matrix that is a markov chain, and I'm given a state vector. How to use For Loop to plot multiple graphs?. Legend in for loop. Hold on in for loop doesn't work . But instead of getting a side-by-side bars, I got bar graphs stacked on top. Learn more about hold plot When Matlab reads the for statement it constructs a vector, [1:4], and j will take on each value within the vector in order. I tried plotting bar graphs of cumulative rainfall for the months of june, july and august (13 weeks) of 6 consecutive years in matlab using for loop. Show Hide all comments.
