axis command enables you to adjust the scaling of graphs. By default, MATLAB finds the maxima and minima of the plotted data and chooses appropriate axes ranges. You can override the defaults by setting axis limits.
axis([xmin xmax ymin ymax zmin zmax])You can control how MATLAB scales the axes with predefined
axis options:
axis auto returns the axis scaling to its default, automatic mode. v = axis saves the scaling of the axes of the current plot in vector v. For subsequent graphics commands to have these same axis limits, follow them with axis(v).
axis manual freezes the scaling at the current limits. If you then set hold on, subsequent plots use the current limits. Specifying values for axis limits also sets axis scaling to manual.
axis tight sets the axis limits to the range of the data.
axis ij places 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 places 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.
