Change graph date when 'date unused'
So I have some mini-graphs displaying live data with absolute timestamps. Because the graphs are small and only display 24 hours of data - I turn off the extra date line by setting 'date unused' in the properties:
Now if I want to zoom in on the last hour of data, I would change the start of the x-axis to "9:05:41" but as the previous value was 22:05:41 *yesterday* it then shows the last 25 hours of data (i.e. it's still yesterdays date). I can't seem to find a way to change the (hidden) date to today.
How can I change the date when the date is unused? I was wondering if there was maybe a little graph/chart trick I was missing to save me having to try and do it programmatically - I tried copying+pasting but that didn't work.
Hi Sam,
even when the date is not shown to the user you still have the date in your underlying data!
So instead of plain "09:00" you should provide a value of "1d 09:00" (with "1d" marking the day you want to display…
(Or to put it in a different way: when you want to display the last hour of data you need to set x_min := "x_max - 3600"!)
