The yyaxis function creates an Axes object with a y-axis on the left and right sides.Axes properties related to the y-axis have two values.However, MATLAB ® gives access only to the value for the active side. My x-axis is the list of cities. Improve this question. For example, if the left side is active, then the YDir property of the Axes object contains the direction for the left y-axis. Select axis limits to span the range of the data (when XLimMode, YLimMode, and ... MATLAB changes the axis limits to satisfy the two constraints placed on the axes. Use this option if you change the limits and then want to set them back to the default values. Active 4 years, 7 months ago. For an automatically calculated minimum or maximum limit, use -inf or inf, respectively. This command sets the XLimMode property for the axes to 'auto'.
