Missing data with cusom:apexcharts-card

[sten-tor]

I recognized missing history data when using the custom apexchart-card. Several recent hours of history are not displayed correctly.

Hard refresh (Strg+F5) doesn't help.

Same on different browsers and Android. Since the history lags are different on different browsers, I assumed it's a matter of caching. So I was able to reveal the correct data by clearing the cache (chrome://settings/content/siteDetails?site=http...).

The strange thing is that it works correctly in edit mode (see screenshot).

Try to increase the parameter for maximum data points from history. It is in instance settings, where you select from what adapter to get the history.
I am not sure why it works in edit mode. But usually that is the problem.

increase the parameter for maximum data points

I tried that, but it didn't work either.

But I finally found the solution or lets say a workaround: the "cache" parameter has to be set to false, then it works as it should. However, I wonder how this setting affects performance.
