Legend Size

By default, legend takes 20% - 25% of the chart’s height horizontally, when it is placed on top or bottom position and 20% - 25% of the chart’s width vertically, when placed on left or right position of the chart. You can change this default legend size by using the width and height property of the legendSettings.
