Updating parameter, plus plot, with slider input "in real time"

I am fairly new to MATLAB and am working with code that generates eight different subplots from a set of input parameters (the program already exists, and I am just its most recent user)

I want to be able to change these parameters "in real time" by manipulating the sliding bars (creating the sliding bars with the correct properties is as far as I've been able to get so far) and have these plots then update with the new parameters that the slider is set to (also "in real time"), all without having to re-run the function from the command window

Is there a convenient way to do this in MATLAB (ideally without having to rewrite the code for every single one of the subplots)? And if I am able to do this for one parameter, can I simply extrapolate from it to the rest of the parameters?

Thanks!

There are two main ways to interactively update a plot with a slider.

1. Create a Live Script with an interactive numeric slider (this is probably what you want).

2. Create an App that incorporates a uislider (this is more customizable but will require more coding).

Thank you! I will give this a try!

See the doc:

I have, and, unfortunately, this is not working -- at least not without rewriting the entire code for each individual subplot and some very heavy reworking of the entire program structure. What I'm looking for is a way to update an individual parameter and then refresh all eight subplots using that newly updated parameter without executing a new command in the command window, if such a thing exists

So you have to post your code for further help. Otherwise it's difficult, if not possible to guess what you want.

I will need to request permission to post the code here. But, just to reiterate, I'm looking to update parameters in real time using GUI sliders, and to refresh the subplots relying on those parameters without reissuing the function command in the command window.

It's not, as the linked document suggests, merely a restatement of one coordinate axis of one plot -- each of these subplots relies on a different combination of the same parameters, and, ideally, the parameter itself should be what's changing
