I have a live data plot (from NI DAQ sampled every second) diplayed on an app. The plot shows the last 5 minuts of data, and normaly has an x tick mark every minute; but every once and a while it switch to a xtick mark every 30 seconds, then back to every minute. This makes the plots seem a little glitchy as the grid marks show up then disapear. I see all the documentation about controlling the x tick marks, but this method would require code for each time the plot is updated (every second).

I'm wondering if there is a clever way to say this plot has excatly 5 x tick marks once then the plot would not bounce around with amount of tick marks. I'm trying to be stingy with amount of code that is run every second.

Thanks
