noDataText for PieChartView isn't working.

[SatishBirajdar007]

Hello,

I want noDataText label shown when there is no element to be shown, so I added

pieChartView.noDataText = "No data available"

in ViewDidLoad and also in ViewWillAppear

But it isn't working, any help?

make sure you meet:

        if _data === nil && noDataText.characters.count > 0
        {
            context.saveGState()
            defer { context.restoreGState() }
            
            ChartUtils.drawMultilineText(
                context: context,
                text: noDataText,
                point: CGPoint(x: frame.width / 2.0, y: frame.height / 2.0),
                attributes:
                [NSAttributedStringKey.font: noDataFont,
                 NSAttributedStringKey.foregroundColor: noDataTextColor],
                constrainedToSize: self.bounds.size,
                anchor: CGPoint(x: 0.5, y: 0.5),
                angleRadians: 0.0)
            
            return
        }
