Hi There!

I created a UserControl that contains amongst other stuff a SciChartSurface. That control can be resized by the user to any size and is together with a lot of other stuff in a grid. The user can create a PDF of the whole whole grid using RenderTargetBitmap.

For the PDF the grid is resized by a factor x to get a higher resolution. All children of that grid are repostioned and so on and it all works. The Chart looking really good in the PDF, but the TickLabels are not resizing when changing the FontSize of their axis.

I tried to bind the FontSize in the TickLabelStyle to the Axis FontSize in XAML and tried to set the binding in code behind but I can’t get it to work.

Anyone got an idea how to set TickLabelStyle.FontSize the same as its axis FontSize?

UPDATE: Manged to set a binding in the TickLabelStyle to the upper NumericAxis, but now I have the tick labels font size changing itself between the new and old font size all the time until I it change back to the old font size.

Thanks for any help!

Hello again!
I’m working with creating labels on renderable series using renderContext.DrawText in overrided InternalDraw method. I had a problem: for example, if there are two renderable series with different series colors, all chars look good (see image 1). But if these renderable series have the same color, chars begin to render in strange way (see image 2).
How can I fix this bug?

P.S. It is only my suggestion, but is there some kind of cache that i need to clean?
I’ve attached project below.

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


    // 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()
            .withStrokeStyle(ColorUtil.White, 3f, false)


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


and the result :
