Unable to set background color to clear color for the graphs.

ℹ chartview.backgroundcolor = uicolor.blue , the color is changed to blue.

What did you expect to happen?

ℹ Tried changing the background color of the spritekit view but no use.

What happened instead?

ℹ chartview.backgroundcolor = uicolor.clear , the color is not changed to transparent.

ask on stack overflow unless you sure it's a bug.
but currently,

    internal func initialize()
    {
        #if os(iOS)
            self.backgroundColor = NSUIColor.clear
        #endif

it's already clear color.
