MATLAB: I have the index value from a plot. Now what

indexplot

Hello,

I have created a plot, any plot will work. Then went in with data cursor function within the plot, right clicked and exported the cursor data. The cursor info, produced a 'DataIndex' value. Say I want the plot to start at the provided index value, how would I go about that?

I am also attempting to create a beginning and end function as I have to use this time interval multiple times.

Example:

Beginning= ____ %the index value, this is where I am not sure how to use the indexed value

End = max(time) %the end of the plot

TimeInterval = (Beginning:End)

plot(load(TimeInterval),deflection(TimeInterval))

Thank you,

Cory

plot(load(TimeInterval),deflection(Beginning:end))

That is, use the same indexing of your y data as you used for your x data. You were attempting to use your x values to index your y values, instead of using the positions to index each of them.

MATLAB: Cannot zoom x axis properly with multiple 2D plots in same figure – linkprop

Create a zoom mode object for the figure. Use a ButtonDownFilter to filter out requests that are not over any of the axes. Create a ActionPostCallback that figures out which axes was zoomed and then goes around to all of the other axes and does appropriate setting of the axes limits for them.

Or instead of using ButtonDownFilter and having to figure out which axes it was, you could (depending on what else you need to do) set HitTest off on all of the objects in all of the axes, leaving only a single axes (but not its children) with HitTest on. The zoom would then be known to be against that one axes, so you could skip the ButtonDownFilter and checking of which axes was touched and go ahead and set the xlim appropriately for all of the other axes.

MATLAB: How to update x-axis limit of a TIMESERIES plot in MATLAB 7.8 (R2009a)

As of MATLAB 7.8 (R2009a), the XDATA of a TIMESERIES plot is expressed in days relative to the StartDate of TIMESERIES (DATENUM(b.TimeInfo.StartDate) in the example) and not in absolute DATENUM values. This avoids rounding problem in plotting TIMESERIES with numerically small time values expressed relative to a large StartDate offset. To update the x-axis limits, use the time vector itself after converting to days, for example:

xBegin = 0; % starting x-limit relative to the StartDate
xEnd   = 0.0417; % where 0.0417 is a fractional number of a day
xlim([xBegin xEnd])
