Hello, I'm trying to get some charts working for an internal demo. We're using F# with all elements declared in code (not in XAML).
The charts seem to work well in our UWP app but they don't display in our Android app.
Here's the sample code I'm using for the chart itself:
type DataPoint = { Name : string; Value : float }
let dps : DataPoint list = [{Name="1"; Value=5.};{Name="2"; Value=10.};{Name="3"; Value=15.};{Name="4"; Value=20.}]
let series:BarSeries = new BarSeries()
series.ItemsSource <- dps
series.XBindingPath <- "Name"
series.YBindingPath <- "Value"
series.DataMarker <- new ChartDataMarker()
series.EnableTooltip <- true
let chart:SfChart = new SfChart()
chart.Legend <- new ChartLegend()
chart.Legend.LabelStyle.FontSize <- (float32)14.
chart.Legend.DockPosition <- LegendPlacement.Bottom
chart.Legend.Orientation <- ChartOrientation.Horizontal
chart.Legend.LabelStyle.Margin <- new Thickness(10., 0.)
chart.Series.Add(series)
The chart is then put inside a ContentView -
new ContentView(Content = chart, Padding = new Thickness(defaultSpacing), MinimumHeightRequest = 500., HeightRequest = 500., MinimumWidthRequest = 500., WidthRequest = 500., HorizontalOptions = LayoutOptions.FillAndExpand, VerticalOptions = LayoutOptions.FillAndExpand, BackgroundColor = Color.Transparent)
Which is the added to a Grid with these properties set (among others) -
self.BackgroundColor <- (defaultArg style.BackgroundColor Colors.Transparent).Xamarin
self.Opacity <- defaultArg style.Opacity 1.
self.HorizontalOptions <- LayoutOptions.Fill
self.VerticalOptions <- LayoutOptions.Fill
self.ColumnSpacing <- defaultSpacing
self.RowSpacing <- defaultSpacing
self.Padding <- Thickness(defaultSpacing * 3., defaultSpacing * 1.6)
There don't seem to be any errors in logcat.
