Temperature graph in dashbord

I have a annoying issue in dashboard and i dont know where to clear it.
A Temperature card can provide a history graph totally fake like this image shows it !

Where do i correct this ?
Help would be appreciated

It’s not the graph that is the problem it is your sensor.

Even so the sensor is the problem ( or ZwaveJs ) my question was about how to clear thoses dummy datas and finally having this unusefull graph corrected.
More usefull answer for me

In fact all history datas are correct the graph is not

The graph is generated from stored history (or LTS) data so that simply isn’t possible.

In the history I finally found a temperature of 52999,5 °C I will investigate where it comes from
i had a simple question, no corresponding answer, I understand I will search the answer by myself.
no problem for me, any way
and I found the answer … the recorder does the job … and a call to service recorder.purge … is used to purge datas
