Android FontSize   Error   android   utf8   typeface

hi everyone
when i use utf8 string such as ‘محور’ = axis in persian sciChart lookLike this .
i tried different fonts but did not work .

 SciChartBuilder.init(this@Main2Activity)

    // Obtain the SciChartBuilder instance
    val sciChartBuilder = SciChartBuilder.instance()

    val myCustomFont: Typeface? = ResourcesCompat.getFont(this, R.font.maryam)
    val fontStyle = FontStyle(myCustomFont, 50f, Color.RED)

    val s = String("محور".toByteArray(Charsets.UTF_8))

    xAxis = sciChartBuilder.newNumericAxis().withAxisTitleStyle(fontStyle).withAxisTitle(s).withGrowBy(DoubleRange(0.1, 0.1)).build()
    yAxis = sciChartBuilder.newNumericAxis().withAxisTitle("this is y").withGrowBy(DoubleRange(0.1, 0.1)).build()

    val dataSeries = XyDataSeries(Double::class.javaObjectType, Double::class.javaObjectType)
    dataSeries.append(arrayOf(0.0, 2.0, 4.0, 6.0, 8.0, 10.0), arrayOf(1.0, 5.0, -5.0, -10.0, 10.0, 3.0))

    rs = sciChartBuilder.newColumnSeries()
            .withDataSeries(dataSeries)
            .withStrokeStyle(ColorUtil.White, 3f, false)
            .build()

    surface.chartModifiers.add(sciChartBuilder.newModifierGroupWithDefaultModifiers().build())

    UpdateSuspender.using(surface) {
        Collections.addAll<IAxis>(surface.xAxes, xAxis)
        Collections.addAll<IAxis>(surface.yAxes, yAxis)
        Collections.addAll<FastColumnRenderableSeries>(surface.renderableSeries, rs)

    }

and the result :

Logging SciChart exceptions?
Android Exception   Error   android   logging   monitoring

Hi,

I’m evaluating SciChart for use in a production app.

Is there any way to log exceptions generated by SciChart? Currently I’m logging all handled and unhandled exceptions in my app to my server so that issues can be flagged without users having to manually submit support tickets. SciChart is printing internal exceptions to console – is there any way to override that with our own error handling mechanism? If not, how should we monitor for production errors generated internally by SciChart?

Thanks

I have 2 charts in my application. They work fine until I add an event to the chart (xaml). The Designer gives an Unhandled Exception with the following details

The Chart code is as below. If I remove the Preview mouse down and reload then it woks fine.

        <s:SciChartSurface x:Name="sciChartFull" s:ThemeManager.Theme="Chrome" Grid.Column="0" PreviewMouseDown="sciChartFull_PreviewMouseDown"  >
            <s:SciChartSurface.RenderableSeries>

                <s:XyScatterRenderableSeries x:Name="pointSeriesFull">
                    <s:XyScatterRenderableSeries.PointMarker>
                        <s:EllipsePointMarker Width="5" Height="5" Fill="#FF04571B" Stroke="#FF04571B" StrokeThickness="1"></s:EllipsePointMarker>
                    </s:XyScatterRenderableSeries.PointMarker>
                </s:XyScatterRenderableSeries>
            </s:SciChartSurface.RenderableSeries>
            <s:SciChartSurface.XAxis>
