Enabling a Smoother Line in Graph Builder with Local Data Filters

S_Reisch — Sun, 11 Jun 2023 11:06:02 GMT

I'm using JMP 15 Graph Builder to plot points as well as a smoother line. When I apply a local data filter, the smoother line disappears and only the points are displayed. Is it possible to make the smoother line show up when using a local data filter?

The smoother should be drawn as long as there are at least 2 points remaining. Can you display what you are seeing so it can help the community figure out the issue

Below are two screenshots of the graph builder with and without a local data filter applied. The smoother disappears in all my JMP tables when I apply a data filter to any column. Please let me know if there is any other information that would be helpful.

I am stumped on this one....I hope another community member has some insight.

is it possible that the filter is somehow cutting out too much data?

If the data is the same in two columns and both are used for the graph, one for points and one for the smoother, I guess this could happen. I haven't run in to it before.

the smoother requires at least two points (for a line) or 3 points for a fitted line.

Could that be the problem?

That's not the problem, there are many more points than that.

I'm with @txnelson, I can't reproduce this.

Can you share a (non-proprietary) data table that shows this problem?
What maintenance level of JMP 15 are you running?
How many rows are there in the data table?

I have the issue even when I use any of the JMP sample data sets and apply any sort of local data filter in graph builder. It must be an issue with my local instance of JMP. I'm running JMP 15.0.0. Maybe I should try to uninstall and reinstall JMP unless there are any other suggestions? I don't have admin rights to my laptop so that is easier said than done.

It seems unlikely to be something related to your installation, so uninstalling and reinstalling isn't a step I'd suggest right now.

It could be a bug in 15.0 (though I can't find a bug description that seems related), so instead I'd suggest updating to 15.2. You can get the updater at jmp.com/update.

I'll keep looking at this too to see if I can figure anything out.

I've seen this happen when

there is a row with the Hide flag set, which would cause the smoother to be hidden
AND it has a missing Y value, which prevents it from being used so the Hide flag is ignored
AND the data filter has the "Select Missing" option on, which interferes with the missing value logic of the smoother and the Hide flag is honored after all

In the future, a single hidden row won't cause the smoother to be hidden, but hopefully this helps you work-around the issue if you have these conditions.

Thanks for everyone's feedback!

I downloaded 15.2.0 and I am still running into the issue.

I also still have the issue even when there are no rows hidden and no y values missing.

However I did find that if I uncheck the "Show" box in the data filter it will draw the smoother line, however then it shows the points that I would like to be filtered out.
