  //Sample Data points -> 50,25,100,80,...(your data to be represented in graph)
  private fun calculatePointsForData() {

    val bottomY = getLargeBarHeight() - CURVE_BOTTOM_MARGIN
    val xDiff = width.toFloat() / data.size

    val maxData = data.maxBy { it.amount }!!.amount

    for (i in 0 until data.size) {
      val y = bottomY - (data[i].amount / maxData * bottomY)
      points.add(PointF(xDiff * i, y))
    }
  }
