Hi all,
I am using the iOS SciCharts version to implement a heatmap series in my application. I am testing out the heatmap by providing a test series of random 100 zValues that range from 1-200. The Heatmap with the stops below just appears blue (see image). My suspicion is that either I am not updating the zValues correctly or the andStops is too low. Can anyone provide insights on what could be the issue?

//Test zValues
let SpectTestArray: [Double] = [ 12,  14, 68, 137, 164, 124, 124, 122, 162, 128, 45, 129,  40,  91,  53, 159,  77,  59,   0,  91, 92,  73,  77,  67, 163,  69, 149, 115,  17,  85, 119, 129, 186,  93,  80,  34, 159, 115,  65, 181, 159,  67, 152,  29,   6, 162,  51, 196, 186, 122, 114, 171, 159, 116,  20, 102,   4, 174, 144, 160, 89,  51,  89, 130, 172, 186,  40, 174,  20, 120, 88, 151, 127, 167,  10,  49, 198,  67, 184, 197, 152, 193, 196, 163,  18,  77,  17, 143, 124, 115, 1, 115, 126,  22,  35,   6,  58, 121,  77,   5]

let colors = [UIColor.fromARGBColorCode(0xFF00008B)!, UIColor.fromARGBColorCode(0xFF6495ED)!, UIColor.fromARGBColorCode(0xFF006400)!, UIColor.fromARGBColorCode(0xFF7FFF00)!, UIColor.yellow, UIColor.red]

CH1HeatMapRenderableSeries = SCIFastUniformHeatmapRenderableSeries()
        CH1HeatMapRenderableSeries.dataSeries = CH1SpectDataSeries
        CH1HeatMapRenderableSeries.minimum = 0.0
        CH1HeatMapRenderableSeries.maximum = 200.0
        CH1HeatMapRenderableSeries.colorMap = SCIColorMap(colors: colors, andStops: [0.0, 0.2, 0.4, 0.6, 0.8, 1.0])
        spectchartsurface?.renderableSeries.add(CH1HeatMapRenderableSeries)

        var Spectvalues = SCIDoubleValues(capacity: 100)

        for n in 0...SpectTestArray.count-1 {
            Spectvalues.add(SpectTestArray[n])
        }
//        print(Spectvalues)
        CH1SpectDataSeries.update(z: Spectvalues)
