ROC curve settings

[#1]

Hi there, 

I have created ROC curves and combined several together in one graph. I have understood how to change the colours of the according curves. However I need the graphs to be black and white, hence the lines need to be dotted or dashed which I am unfortunately unable to change. Any tips? much appreciated thanks.

If you right click on the graph, and select Customize, you can change the line color and style

thanks very much for the quick answer. however, when I right click and choose customise I get the script version (see below) and I am not very good at "programming". 

any tips?

It appears from your attached image that you are on an Apple system. I am on a Window's system, which surfaces additional objects in for Customize 

I look to others in the Community who might have an insight to a solution  for you.

Any solution so far, when you encounter the issue of the script during ROC graph customization?
