** Plot axis scaling and appearance. **

** AXIS([XMIN XMAX YMIN YMAX]) sets scaling for the x- and y-axes **

** on the current plot. **

** **

** **

** AXIS([XMIN XMAX YMIN YMAX ZMIN ZMAX]) sets the scaling for the **

** x-, y- and z-axes on the current 3-D plot. **

** **

** **

** AXIS('auto') returns the axis scaling to its default, automatic **

** mode where, for each plot, xmin = min(x), xmax = max(x), etc. **

** **

** **

** V = AXIS returns a row vector containing the scaling for the **

** current plot. If the current plot is two-dimensional, V has **

** four components; if it is three-dimensional, V has six components. **

** **

** **

** AXIS(AXIS) freezes the scaling at the current limits, so that if **

** HOLD is turned on, subsquent plots will use the same limits. **

** **

** **

** AXIS('ij') puts MATLAB into its "matrix" axes mode. The coordinate **

** system origin is at the upper left corner. The i axis is vertical **

** and is numbered from top to bottom. The j axis is horizontal and **

** is numbered from left to right. **

** **

** **

** AXIS('xy') puts MATLAB into its default "Cartesian" axes mode. **

** The coordinate system origin is at the lower left corner. The x axis **

** is horizontal and is numbered from left to right. The y axis is **

** vertical and is numbered from bottom to top. **

** **

** **

** AXIS('equal') changes the current axis box size so that equal tick **

** mark increments on the x- and y-axis are equal in size. This makes **

** PLOT (SIN (X),COS (X)) look like a circle, instead of an oval. **

** AXIS('square') makes the current axis box square in size. **

** AXIS('image'), for images, makes the aspect ratio the same size as **

** the image. **

** **

** **

** AXIS('normal') restores the current axis box to full size and **

** removes any restrictions on the scaling of the units. **

** This undoes the effects of AXIS('square') and AXIS('equal'). **

** **

** **

** AXIS('image') sets the aspect ratio and the axis limits so the **

** image in the current axes has square pixels. **

** **

** **

** AXIS('off') turns off all axis labeling and tick marks. **

** AXIS('on') turns axis labeling and tick marks back on. **

** **

** **

** [S1,S2,S3] = AXIS('state') returns strings indicating the **

** current setting of three axis properties. **

** **

** **

** S1 = 'auto' or 'manual'. **

** S2 = 'on' or 'off'. **

** S3 = 'xy' or 'ij'. **
