ios-charts background color

Hi would like to change the background color of my iOS-chart.

I tried:

barChartView.backgroundColor = UIColor.redcolor()

But it changed the color around my bargraph, not the color inside, ie. behind the vertical bars.

Any Idea?

Solution

  • barChartView.backgroundColor references the UIView of which your BarChartView is a subview. You need to reference the base class of the BarChart itself to change the properties of the bars or the grid behind the bars. To change the color of the space behind the bars try:

    barChartView.gridBackgroundColor = UIColor.redcolor()
