How do I fit a spline to my scatter plot, without showing the scatter points in my plot?

What I am doing now is draw a scatter plot of my data points and then use basic fitting toolbox to fit a spline. But, it also shows the scattered points which I don't want to show. Is there any way to do this? Thank you.

Programmatically, assuming x and y are the vectors of your scatter plot, you can try the following

xx = min(x):0.001:max(x); % change your step size (currently 0.001) based on desired plot smoothness
yy = spline(x,y,xx);
plot(xx,yy)

You can see some examples in the spline documentation: https://www.mathworks.com/help/matlab/ref/spline.html
