Chart error in openhab.log


what does this mean?

[o.u.i.items.ItemUIRegistryImpl] - Cannot retrieve visibility item selectChartIntervall for widget org.openhab.model.sitemap.Chart


It probably means that the Item whose state you are using to determine when to show the chart or hide it is uninitiailzed or doesn’t exist (typo?).

It would be helpful to see your sitemap line.

i c&p’ed an example for a chart, and this could be my problem …

Chart item=num_homebb01_tempds01 service=“mysql” period=24h refresh=300000 visibility=[selectChartIntervall==0, selectChartIntervall==“Uninitialized”]

i did not know any more where i found this example.

because of my stupid noobs beginner level, i didn’t recognize the visibility tag.
