given mean function, variation/or co-variance matrix, can I plot some graph like what normally used for gaussian process.

Hi, I've got a mean function and variance and covariance of some data. I am able to draw a graph with error bar such as below.

But I want to have an light colored area such as we normally see with plot from gaussian process such as below. Is there any ways to get such graphs but without going through GP model.

patch with the vertices of your errorbars, maybe...

Hi, dpb, thank you. Managed to got such plot by fill function. Basically same as patch.
