You are talking about the grid-background

• setDrawGridBackground(boolean enabled): If enabled, the background rectangle behind the chart drawing-area will be drawn.
• setGridBackgroundColor(int color): Sets the color the grid-background should be drawn with.

Can we set gradient drawable to Grid background?

Here's a workaround.

private fun LineChart.setGridBackgroundDrawable(drawable: Drawable) {
        background = object : Drawable() {
            override fun draw(canvas: Canvas) {
                val paint = Paint()
                // In case you want to change the color outside the content.
                // paint.setColor(xxx)
                canvas.drawRect(bounds, paint)
                drawable.bounds = contentRect.toRect()
                drawable.draw(canvas)
            }

            override fun setAlpha(alpha: Int) {
            }

            override fun setColorFilter(colorFilter: ColorFilter?) {
            }

            override fun getOpacity(): Int {
                return PixelFormat.TRANSLUCENT
            }

        }
    }

Simply use

lineChart.setGridBackgroundDrawable(getDrawable(R.drawable.gradient)!!)
