The problem

Detailed charts can be displayed, but rough charts lack data

I wrote a simple integration myself, which should be a numerical sensor. Every second, the sensor data is pulled from the cloud and displayed. However, I found that clicking on this entity displays a chart with no data, but when all the data is displayed, there will be data. Why is this

What's the state class of the entity?

[ALEXgogodo]

the enumeration type of SensorStateClass and SensorDeviceClass

[joostlek]

No clue why this happens, don't see anything strange at the code, maybe it's a frontend issue?

[joostlek]

Can you show the entity in the dev tools?

[ALEXgogodo]

One of my light sensors.

[ALEXgogodo]

I have found that this phenomenon often occurs on the light sensor, occasionally on the PM25 sensor, but other sensors are normal, such as temperature and humidity. Is it because my light sensor type is set incorrectly? But when displaying details, the data on the chart is visible. I have two light sensors that do not display the small chart, but the large chart is normal.
