actions via mouseover ? - use a modifier Key 👉🔳

hogi — Sun, 18 May 2025 06:52:21 GMT

Hi,

I wanted to trigger an action via a data point.

The approach via Hover Label / Click is way too slow:
one has to wait till the hover label appears, then one has to "find" the link and click.

On the other hand: when I use Hover Label / "Picture" the result - yes, is very fast - but too uncontrolled.
Whenever the user moves the mouse over a data point, the action is triggered. buah!

So, my final solution was to trigger the action just if a Modifier Key is pressed, like here with CTRL:

The result:
JMP as interactive as we love it : )

If user stops on top of a point, it will still trigger as Is Control Key() will return non-zero value. This might of course be what you want (not really sure why JMP does that, maybe Is Control Key() is very finicky depending where it is used?). I usually prefer adding links to my hover labels to open web pages or trigger actions as it provides much more control on what I want to do (and still hover labels trigger too much).

Which version of JMP are you using?

on my system it works nicely:
CTRL pressed -> link is opened

no CTRL -> no link is opened.

via the Modifier Key, the user can decide if an action should be executed.
"hover label trigger too much" -> no issue here :)

I just removed the compressed column such that the table can be opened with JMP17.
-> works as well.

I'm fairly sure I was using JMP 18.0.1. The issue hasn't re-appeared so I think JMP had left something weird in memory which caused it to open when I let the hover label appear.

There is still the issue of hover label triggering too much, if you hold ctrl and have few points very close to each other -> all will trigger (or some) but is one of the (many) issues with hover labels we currently just have to live with. In the case of your example data it isn't that bad as you can just make the plot larger -> more space between points.

If a hover label is already open for a data point, JMP doesn't have to calculate the values (again).
no calculation -> no action triggered

So, take care that the hover label gets closed before you try to trigger actions via CTRL.

nice application case:
Jeopardy game (see by @scwise and @Jed_Campbell )
One can use the hoverlabel framework to open the question directly with the mouseover - without the detour via the actual hover label.
