How to pass a variable from javascript to TOOLTIP

[nerixs]

Hello,
Thanks for your confirmation.
Would you have any idea or an example that would display changes (T.Ext and T ° INT) over a 24-hour period?
We do not know how to approach the thing.
Best regards.

Hi nerixs,

I don't get this, could you explain?

"...would display changes (T.Ext and T ° INT) over a 24-hour period?"

Regards.

Currently, the curve displays the interior temperature (T ° Int) as a function of the exterior temperature (T.Ext).
I would like to post any changes over a 24 hour period.
A second X axis? I do not know how to do.

Hi,
Do you want to build something similar to a meteogram?

Hello,
Yes, that’s a good possibility.
My X axis (T.Ext) would be replaced by Hourly from 0 to 24 (with a scroll if possible), but I do not understand how to reinstate my values (T ° Int, T ° Csg, Date and especially T. Ext).
Do you have time for an example?
Best regards

Hi,
You can show time at the second axis type data, that's should resolve your problem.

Hello,
Thanks for your help.
I did not understand your example, on the X axis I have ("T.Ext" = 1611878400000 °, 1611878400001 ° and 1611878400002 °).
I don't have the time display on the 2nd axis.
Best regards

Hi,

This is value of time based on a timestamp derived from Unix time.
Look at this example, it showing a concept where xaxis is type datatime and you can show something in time.
