Hello!

I am plotting rasters and average firing rates for cells. To plot the average firing rates with the standard deviation I am using a function that plots the standard deviation using 'fill' with an alpha of 0.1, then plots the mean over it in a darker color (see plot). The legend seems to pick up the lighter color, making it very difficult to interpret when the number of classes gets beyond 2-3.

Is there a way to ensure that the legend picks up on the darker colors, perhaps manually?

I tried to assign the legend to the lower subplots but then it takes the first 12 dots (only 2 colors), which is even less helpful.

Ah I see, the issue was the order I was calculating the firing rates in (I needed to calculate mean first and then the std error, so the mean shows up on the legend). Thank you both!

Haha this data is in response to people watching videos involving those people!

Thank you both for the help!

Interesting! I wonder if subjects are equality familiar with the two.

Copying the answer dpb gave in the comments so I can accept it.

"legend assigns the strings to the first handles in the axis in sequential order; if you want a different element titled, you need to save the handles to them and then pass that array to legend as the first parameter."
