Android SciChartLegend xamarin ios android

Hello.

I am working on Xamarin Android project with C#. Since having a legend within the chart causes problems with too many axis’ (no scrolling is available thus selecting different series in a legend becomes unavailable) and having a legend outside of chart area, anywhere we desire, would be of a preference, is there a tutorial on how could I achieve such a thing? Our project needs this functionality for both Android and iOS.

Would be grateful if anyone could help out with this issue.

Thank you in advance!

Legend outside of chart area

iOS Legend SciChartLegend ios xamarin.ios

Hello.

I have previously asked a question regarding Android and Xamarin (https://www.scichart.com/questions/android/legend-outside-of-chart-area).

Now, I have the same question, but for iOS. Do you have any examples available for taking chart legend outside of chart area on iOS?

Thank you and have a nice day!

Regards,
Paul.

Hello Team,

In Pie Chart with DonutSeries, the segment spacing seems to have no effect on graph.

donutSeries.segmentSpacing = 10

Crash when using rollover modifier

iOS RolloverModifier ios interaction

I’m getting the following crash:

2020-02-14 16:45:43.902812-0500 CommonStock Development[2425:710225] -[SCIRolloverModifier onTouchesCancelled:]: unrecognized selector sent to instance 0x282ffe080
2020-02-14 16:45:43.904098-0500 CommonStock Development[2425:710225] *** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[SCIRolloverModifier onTouchesCancelled:]: unrecognized selector sent to instance 0x282ffe080’

whenever I try to scrub my chart, I must also note that in order for the legend to show, I have to tap really hard on the surface.

This is my code:

func set(data set: SimpleChartDataSet, alternate: SimpleChartDataSet) {

    let lineDataSeries = SCIXyDataSeries(xType: .double, yType: .double)
    let dashedDataSeries = SCIXyDataSeries(xType: .double, yType: .double)

    let group = DispatchGroup()
    group.enter()

    DispatchQueue.global(qos: .userInteractive).async {
        for (index, i) in set.enumerated() {
            lineDataSeries.append(x: Double(index), y: Double(i))
        }

        for (index, i) in alternate.enumerated() {
            dashedDataSeries.append(x: Double(index), y: Double(i))
        }

        group.leave()
    }

    group.notify(queue: .main) {

        let lineSeries = SCIFastMountainRenderableSeries()
        lineSeries.zeroLineY = set.min() ?? 0.0
        lineSeries.dataSeries = lineDataSeries
        lineSeries.strokeStyle = SCISolidPenStyle(color: UIColor.green, thickness: 2.0)
        lineSeries.areaStyle =  SCILinearGradientBrushStyle(start: CGPoint(x: 0, y: 1), end: CGPoint(x: 0, y: 0), start: UIColor.green, end: UIColor.clear)

        let dashedSeries = SCIFastLineRenderableSeries()
        dashedSeries.zeroLineY = set.min() ?? 0.0
        dashedSeries.dataSeries = dashedDataSeries
        dashedSeries.strokeStyle = SCISolidPenStyle(color: UIColor.white, thickness: 2.0, strokeDashArray: [2.0,2.0,2.0,2.0])

        SCIUpdateSuspender.usingWith(self.surface) {

            self.surface.xAxes.clear()
            self.surface.yAxes.clear()
            self.surface.renderableSeries.clear()

            let xAxis = SCINumericAxis()
            xAxis.drawLabels = false
            xAxis.drawMajorBands = false
            xAxis.drawMajorGridLines = false
            xAxis.drawMinorGridLines = false
            xAxis.drawMinorTicks = false
            xAxis.drawMajorTicks = false
            xAxis.drawLabels = false

            let yAxis = SCINumericAxis()
            yAxis.drawLabels = false
            yAxis.drawMajorBands = false
            yAxis.drawMajorGridLines = false
            yAxis.drawMinorGridLines = false
            yAxis.drawMinorTicks = false
            yAxis.drawMajorTicks = false
            yAxis.drawLabels = false

            self.surface.xAxes.add(items: xAxis)
            self.surface.yAxes.add(items: yAxis)
            self.surface.renderableSeries.add(items: lineSeries, dashedSeries )
            self.surface.chartModifiers.add(SCIRolloverModifier())
        }
    }
}
