Saving MT5 2D/3D optimisation charts



I've run some heavy-duty optimisation and I'd like to ideally save the 2D/3D charts so that I can see stable parameter values for my EA. Is this done by saving the .OPT file? I always export the results which I have been doing for some time but my EA is fairly quantitative and I want to see what the best parameter values are so that I can backtest and forward test more efficiency to determine pair-based .SET files. To do that, it's really helpful to see the 2D/3D charts that MT5 generates, but I'd like to know if there is a way to save those in a file so that they can be reopened with MT5 or whether they are essentially deleted as soon as the tabs/windows are closed n MT5. Help is appreciated!
