using GUIDE I have now a programm whose output is a vector and a plot of its data. Because the plot has many little variations, I used the csaps function to get a smoothier plot. I want now to add a slider to my figure to change the smoothing parameter and I want that the plot to be updated each time the value of the slider changes. How can I do this? I found this on mathworks.com but I coudn't apply it to my case: https://de.mathworks.com/help/control/ref/stepplot.html .
