Understanding Axes Aspect Ratio for more information on how axis limits affect the axes. Setting the Aspect Ratio and Axis Limits for related functions import numpy as np you probably alredy do this so no extra overhead fig, axes plt.subplot() ot(data:,0, data:,1) xlim axes.getxlim() example of how to zoomout by a factor of 0.1 factor 0.1 newxlim (xlim0 + xlim1)/2 + np.array((-0.5, 0.5)) (xlim1 - xlim0) (1. 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 for the x-axis and for the y-axis originally selected by MATLAB. To add to Hima's answer, if you want to modify a current x or y limit you could use the following. If you set the limits on an existing graph and want to maintain these limits while adding more graphs, use the hold command. Note that high-level plotting functions like plot and surf reset both the modes and the limits. Setting a value for any of the limits also sets the corresponding mode to manual. 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. Xlim, ylim, and zlim set or query values of the axes object XLim, YLim, ZLim, and XLimMode, YLimMode, ZLimMode properties. When you do not specify an axes handle, these functions operate on the current axes. Specify the limit method as 'tickaligned', 'tight', or 'padded'. xlim (limitmethod) specifies the limit method MATLAB uses for automatic limit selection. Specify limits as a two-element vector of the form xmin xmax, where xmax is greater than xmin. Example: ax.XLim 0 10 Example: ax.YLim -inf 10 Example: ax. xlim (limits) sets the x -axis limits for the current axes or chart. MATLAB uses the 'tight' limit method to calculate the corresponding limit. Performs the set or query on the axes identified by the first argument, axes_handle. For an automatically calculated minimum or maximum limit, use -inf or inf, respectively. Sets the respective axis limit mode to manual. For Cartesian axes, specify the limits in one of these forms: xmin xmax ymin ymax Set the x -axis limits to range from xmin to xmax. Axis limits, specified as a vector of four, six, or eight elements. imagesc (Zc, 400 600) axis image colorbar. This is just another convenience for setting the color limits. caxis ( 'auto' ) Then ImageAnalyst asked about the low high syntax for imagesc and imshow. Returns the current value of the axis limits mode, which can be either auto (the default) or manual. limits Axis limitsfour-element vector six-element vector eight-element vector. You can also use caxis to quickly get back to automatic computation of color limits. Sets the axis limits in the current axes to the specified values. With no arguments returns the respective limits of the current axes. Each operates on the respective x-, y-, or z-axis. Note that the syntax for each of these three functions is the same only the xlim function is used for simplicity. Xlim, ylim, zlim (MATLAB Functions) MATLAB Function Reference
