correlation map with categorical and numerical factors

I have several dataset to analyze. I know how to do a color correlation map with numerical factors in JMP but I do not know how to do a correlation map with categorical and numerical factors. That would be very useful because correlation maps are a compact way to analyze and present a lot of information, especially when there are many factors. 

How can I generate a correlation map with categorical and numerical factors?

Is there an alternative method to analyze correlations between many factors of different type?

Re: correlation map with categorical and numerical factors

The Response Screening platform is really great at analyzing correlations between large numbers of factors, and it can compare lots of different data types. A good trick is to put all your columns in both the X and the Y role during the launch.

Re: correlation map with categorical and numerical factors

Thanks for the quick reply and for the suggestion. I have to go deep in the response screening since I am not familiar with that.

About the correlation map, I see that in the multivariate, it accepts only numerical values and the range for correlation coefficients is  between -1 and 1. In the DOE module, I can evaluate a test matrix with a correlation map that accepts all factors, including categorical, and the range for the correlation coefficients is between 0 and 1. I am wondering whether this second type of correlation map is available outside the DOE module to make analysis of correlation of data from experiments.
