Info

axisaxis auto sets <strong>MATLAB</strong> to its default behavior of computing the current axes’limits automatically, based on the minimum and maximum values of x, y, andz data. You can restrict this automatic behavior to a specific axis. For example,axis 'auto x' computes only the x-axis limits automatically; axis 'auto yz'computes the y- and z-axis limits automatically.axis manual and axis(axis) freezes the scaling at the current limits, so thatif hold is on, subsequent plots use the same limits. This sets the XLimMode,YLimMode, and ZLimMode properties to manual.axis tight sets the aspect ratio so that the data units are the same in everydirection. This differs from axis equal because the plot box aspect ratioautomatically adjusts.axis fill sets the axis limits to the range of the data.axis ij places the coordinate system origin in the upper-left corner. Thei-axis is vertical, with values increasing from top to bottom. The j-axis ishorizontal with values increasing from left to right.axis xy draws the graph in the default Cartesian axes format with thecoordinate system origin in the lower-left corner. The x-axis is horizontal withvalues increasing from left to right. The y-axis is vertical with values increasingfrom bottom to top.axis equal sets the aspect ratio so that the data units are the same in everydirection. The aspect ratio of the x-, y-, and z-axis is adjusted automaticallyaccording to the range of data units in the x, y, and z directions.axis image is the same as axis equal except that the plot box fits tightlyaround the data.axis square makes the current axes region square (or cubed whenthree-dimensional). <strong>MATLAB</strong> adjusts the x-axis, y-axis, and z-axis so that theyhave equal lengths and adjusts the increments between data units accordingly.axis vis3d freezes aspect ratio properties to enable rotation of 3-D objectsand overrides stretch-to-fill.2-36
axisaxis normal automatically adjusts the aspect ratio of the axes and the aspectratio of the data units represented on the axes to fill the plot box.axis off turns off all axis lines, tick marks, and labels.axis on turns on all axis lines, tick marks, and labels.[mode,visibility,direction] = axis('state') returns three stringsindicating the current setting of axes properties:Output ArgumentmodevisibilitydirectionStrings Returned'auto' | 'manual''on' | 'off''xy' | 'ij'mode is auto if XLimMode, YLimMode, and ZLimMode are all set to auto. IfXLimMode, YLimMode, or ZLimMode is manual, mode is manual.ExamplesThe statementsx = 0:.025:pi/2;plot(x,tan(x),'-ro')2-37
