Do you mean you want overlaid histograms? If so, that post will explain a couple of ways to do it but I'd caution that it's not a great visualization since the bars of one histogram will cover the bars of the one(s) below it.
Life Distribution is another place that the feature might be already there. It provides two kinds of overlays:
Overlay different distribution fits to the same data and overlay. Access to this type of overlay by using the "Life Distribution" tab of the platform launch dialog. Function types include distribution function, quantile function, and hazard function. But no density function overlay.
Overlay same type of distribution fits to different data sets and overlay. Access to this type of overlay by using "Comparing Groups" tab of the platform launch dialog. Function types include distribution function, quantile function, hazard function, and density function.
The request is along the lines of what's shown above in the post by @shampton82 Excel can also generate similar plots. JMP can provide this in Graph Builder but the summary statistics are not available. Life Distribution provides distribution plots but not histograms, AFAIK.
Similar request regarding @shampton82's post; would also like to have the ability to overlay more than 2 distributions and display process capability (I.e Cpk/Ppk) metrics as part of the summary statistics.
If it's just about a cool looking curve without the Gaussian Fit statistics, one can use histograms 2x with bar and Density setting. The two Overlap Settings can be used to fine tune the heights.
