matlab rounding off while plotting

Hello, I've been taking measurements with many digits, and when I plot them using the plot(x,y,',') function it seems to be less precise. I would see as if many of the data points appear as the same value. I've attached an example file of a capacitor discharging.

I'd appreciate any help!

Thanks

YOu need not to worry about precision....your plot would be correct.

Give the command

format long g

and then examine your data again.

Thanks for your help, Still the same. Is it my data or my plot? Data seems to be fine

I saw in the past that determination tick marks was essentially limited to single precision.

If you are using R2015a or later (not R2014b) you might be able to set the axes XRuler or YRuler TickLabelFormat property to extend the precision.
