Is the alert graph limited to one-hour view?

[Osvaldo-Net]

Hi! I discovered this tool yesterday on Reddit and implemented it right away. So far, I’ve only noticed a few small details (I already opened a bug for the one I consider most important).
However, I have a question: when I try to view alerts over a time range of at least 7 days, the graph doesn’t seem to adjust properly or maybe the graph is designed to display only one hour? Am I doing something wrong?
