I want to plot for all rows consisting of the epochs, learning rate(gamma), and rmse.

I want, as an example, the rmse on the z-axis, the gamma on the x-axis and the epochs on the y-axis. I need to use my data, the one posted above, instead of the data that's actually making the plot (lambda1,lambda2,rmse_abu). How do I do that?

Answer 1

Your posted data does not resemble the plot you are looking for. Nevertheless, I think you should try this to achieve what you are looking for:

I also found this which might be actually more closer to what you are looking for:

How to set x and y values when using bar3 in Matlab?

Answer 2

There's love if you want it. Don't sound like no sonnet!

I hope this works!
