On Kotlin you can set width and height of any view directly using their virtual properties   someView layoutParams width   100 someView layoutParams height   200

If you know the exact size of the view  just use setLayoutParams    graphView setLayoutParams new LayoutParams width  height     Or in Kotlin  graphView layoutParams   LayoutParams width  height   However  if you need a more flexible approach you can override onMeasure   to measure the view more precisely depending on the space available and layout constraints  wrap content  match parent  or a fixed size   You can find more details about onMeasure   in the android docs
