Can MATLAB plot a graph like this? (Ignore the black lines and light blue areas; I only care about the red and blue points.)

Hello everyone, I want to plot the image below. Please ignore the other parts; I'm mainly focused on the red and blue points. I know the scatter function can plot points of different sizes, but the issue is with the red legend next to it. Can MATLAB generate a legend like this, reflecting the size of the points? Looking forward to any responses.

This is a bubble chart. You can create this in MATLAB using bubblechart
The legend isn't exactly the same, but conveys the relationship between size and value.

Ran in:
Here's perhaps a slightly cleaner way.
% create dummy data
t = 0:0.1:10;
y = sin(t);
sz = (y+1)*50;
tiledlayout(1,11)
nexttile([1 10])
scatter(t,y,sz);
ax = nexttile;
scatter(0,1:100,1:100,'r')
ylabel('log_{10}Q')
ax.YAxisLocation = 'right';
xticks([])
% Customimze the displayed size (may not be necessary)
yticks(0:20:100)
yticklabels(0:2:10)

Instead of bubble chart, try scatter where you can specify the color and size of each marker.
