From: FAISAL PEER MOAHMED on 2 Jul 2010 11:49 Hi I have plotted a high frequency data sampled using 50 MS/s having resolution of 10 bits. I can't view this 10 bits in the plot . Is there anyway to increase the resolution ? Regards Faisal

At 50M sampling rate, you'll overload the time axis resolution in a heartbeat, too. Look at what resolution your output device has and figure out how much of a zoom factor you'll have to have to see however much precision you think you need. --
From: FAISAL PEER MOAHMED on 2 Jul 2010 16:22 Thanks I need 10 bit resolution. When I zoom , matlab shows same values at all points. Because the resolution of the plot is only 5 bits. My question here is how to increase the resolution of the plot ?

My > question here is how to increase the resolution of the plot ? .... Me no follow...the data inside a plot is at the resolution of the data passed to the plot function, whichever one was used. If there is 10 bits of resolution in the raw data, there's 10-bits of resolution in the plot data object as it's a double with 52 mantissa bits. There's a disconnect here somewhere but there is still a fundamental issue of how many distinct pixels you can display in a plot axis -- the 17" monitor here is 1152x864 in normal setting; if the figure is full screen the vertical axis is probably only a little over 2/3-rds the height of the screen total which is only a little over half the resolution you'd need to see every distinct possible value of the raw data. Think we need some details on data, plotting technique, etc., to get a better understanding of what are really asking. whos 'x' where 'x' is the variable you're trying to visualize might be a start... --
From: FAISAL PEER MOAHMED on 2 Jul 2010 17:14 Thanks From my understanding Matlab plot has fixed resolution.
