![]() xt xticks returns the current x -axis tick values as a vector. Specify ticks as a vector of increasing values for example, 0 2 4 6. Understanding Axes Aspect Ratio for more information on how axis limits affect the axes. xticks (ticks) sets the x -axis tick values, which are the locations along the x -axis where the tick marks appear. Setting the Aspect Ratio and Axis Limits for related functions 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. If you set the limits on an existing graph and want to maintain these limits while adding more graphs, use the hold command. axis auto sets MATLAB to its default behavior of computing the current Axes' limits automatically, based on the minimum and maximum values of x, y, and z data. The returned values are the current Axes' XLim, Ylim, and ZLim properties. Note that high-level plotting functions like plot and surf reset both the modes and the limits. v has four or six components depending on whether the current Axes is 2-D or 3-D, respectively. You also can change where the x -axis and y -axis lines appear (2-D plots only) or reverse the direction of increasing values along each axis. So, you could do: vmin, vmax plt.gci ().getclim () Share. Specify Axis Limits You can control where data appears in the axes by setting the x -axis, y -axis, and z -axis limits. From there, you just want the getclim method of the ScalarMappable object. whatever the current colorbar would be based on). Setting a value for any of the limits also sets the corresponding mode to manual. If you didn't keep the returned image object, you can use pylab.gci to get the current ScalarMappable (i.e. 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. Performs the set or query on the axes identified by the first argument, axes_handle. 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. Sets the respective axis limit mode to manual. You can also use caxis to quickly get back to automatic computation of color limits. ![]() Returns the current value of the axis limits mode, which can be either auto (the default) or manual. 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
