ZABBIX 4.4.3 Graph protoype widget displays no data

[metal]

images attache d can describe what is happening, first image is from graphs page, second in from the widget. I added a widget with those graph prototypes, but they are all empty on the dashboard, while when I go to the graphs page, and select a graph, it's just OK. Widget settings are also attached.





Any clue on this issue?

thanks

Check the displayed time range.
Is the same time range displayed on the dashboard as the graph that can be displayed normally? The upper graph is the graph for December 17, but the lower graph appears to be the graph for December 10.

[metal]

Thank you for your answer, where can I change that date, I followed your note, you are right indeed, but I could not find the place to change that date, can you please point me out to that place.


Edit
I found it silly me indeed, it is on the upper right corner!

It took me quite some time reviewing the templates thinking there was something wrong with them.

thank you again!

[Atsushi]

Is there a word "Zoom out" in the upper right corner of the dashboard? Since some character string should be displayed on the right side, please click the character string.

I have similar error with a zabbix 5.0.3. I can see without problem the graphs from the last 2 year to 7 days but i don't see any graphs from the last 1 days to 5 minutes.
Follow you will find the zabbix_server.conf
