Hi y'all,
I'm trying to alter the transparency(alpha) of a legend object (the dark blue patch) to match my plot, but when I try to access the children to set the alpha it is empty for some reason? Any idea why this would be or how I could fix it?
Thanks and all the best, Kate

I had the same problem. I couldn't figure out a way to resolve it in Matlab, so instead I exported the graph as it was and then edited the legend in the free photo editing program called paint.net. Though you can use any photo editing program of your choice.
