The grid contains out of lines which can be modified by linestyles and color information. This means that if a plot script containing grid minor is run multiple times, the minor grid will be shown or hidden depending on whether it was run an odd or even number of times. Line properties control the appearance and behavior of a line object. Matlab automatically updates the color, line style, or markers of the line object when you change its seriesindex, or when you change colororder or linestyleorder properties on the axes.
