Loading graphics in Grafana

I am using a Raspberry Pi to show some graphs in Grafana. I only use the raspberry to put the URL in the Chromium. I have shown these graphs for 4 months. But now some of these graphics do not load (line charts).

But if I enter the same URL with my computer the graph is shown. enter image description here

What could be going on? Could it be a memory problem?


Solution 1:

In the end, it was that it was not well set the time in the raspberry and although I entered the URL I had been set to visualize last hour and I was catching the wrong time of day.
