Syntax
Matplotlib plot array size limit? Ask Question Asked 8 years, 1 month ago. Active 1 year, 9 months ago. Viewed 7k times 1. I've created a program that retrieves data from a device on the serial port every half second or so. It then appends that data to the array that sets the data points and then updates the plot. Using fplot, plot this summation for the interval between -1fplot, plot xN(t) on the interval −1≤t. Fplot(f) f is the function or expression for which the plot is to be generated: fplot(f,xinterval)/fplot(f,xminxmax) Xmin- initial limit of the interval from which the plotting f(x) should be initiated. Xmax- final limit of the interval at which the plotting f(x) should be completed: fplot(pt,qt). Fplot(fun, limits). fplot is used to plot a function between specified limits. fun is a function handle to the function to be plotted. limits is a vector specifying the x-axis limits (xmin,xmax) or the x and y axes limits (xmin,xmax,ymin,ymax). fplot is an alternative to plot where, instead of having to generate the x and y coordinates first and passing them as arguments to.
Note that the syntax for each of these three functions is the same; only the xlim function is used for simplicity. Each operates on the respective x-, y-, or z-axis.
Description
xlimwith no arguments returns the respective limits of the current axes.
xlim([xminxmax])sets the axis limits in the current axes to the specified values.
xlim('mode')returns the current value of the axis limits mode, which can be either auto (the default) or manual.
xlim('auto')sets the axis limit mode to auto.
xlim('manual')sets the respective axis limit mode to manual.
xlim(axes_handle,...)performs the set or query on the axes identified by the first argument, axes_handle. When you do not specify an axes handle, these functions operate on the current axes.
Remarks
xlim, ylim, and zlim set or query values of the axes object XLim, YLim, ZLim, and XLimMode, YLimMode, ZLimMode properties.
When the axis limit modes are auto (the default), MATLAB uses limits that span the range of the data being displayed and are round numbers. Setting a value for any of the limits also sets the corresponding mode to manual. Note that high-level plotting functions like plot and surf reset both the modes and the limits. If you set the limits on an existing graph and want to maintain these limits while adding more graphs, use the hold command.

Examples
This example illustrates how to set the x- and y-axis limits to match the actual range of the data, rather than the rounded values of [-2 3] for the x-axis and [-2 4] for the y-axis originally selected by MATLAB.
