multiple plots with optim.logger

[YitzhakSp]

is there a way to have multiple plots in one figure? one plot works fine, but when I do something like logger:add{['training loss'] = loss1 }; logger:add{['test loss'] = loss2} it gives an error. so I define two loggers but the disadvantage is, that they produce two figures instead of one.

@YitzhakSp , why did you close this?

because the answer is found in the documentation:
