Unfortunately, a part of the software development process is giving up features that we hoped would be included in the software. JMP 9 demonstrates that, sometimes, you get an even better feature in return.
For a few releases now, some of you have asked for a tool to let you divide a continuous variable into groups. For example, you may have data for all your sales transactions, and you want to create three groups for the small, medium and large transactions. But where should the cutpoints between those groups be? It would help to look at a histogram of the distribution of transactions to see where to put them.
We weren't able to get a tool like that into JMP 9. But, with apologies to The Rolling Stones, we got what we needed in this case. In fact, we got something better: JMP add-ins.
With JMP add-ins, it's really easy to extend the functionality of JMP through JMP Scripting Language (JSL) and then distribute that extension to other JMP users.
After it's installed, look in the Add-In menu, and you'll find Interactive Binning.
Add-ins are easy to develop, and there's virtually no limit to what they can do. You can call external DLLs, make your own graphs, and call SAS or R.
I'll have another post soon showing how to turn your JSL into an add-in. In the meantime, if you've got an idea for an extension to JMP, post it in the comments. Perhaps you'll see it as an add-in soon.
The library of available add-ins for JMP will grow over time. If you don't find what you want now, keep checking. Maybe you'll get you what you need.
