Xamarin Forms 3.0 Released, WPF support in preview

We stumbled upon the news recently that Xamarin.Forms 3.0 has preview support for WPF! This is really interesting for us at SciChart, as we make iOS Charts, Android Charts with Xamarin Support, as well as WPF charts, but we do not yet have a UWP chart solution. We feel that the API for UWP is incomplete and too immature to make good charting components or applications, so have avoided too much investment into this platform until it showed more promise. Well maybe we won’t have to? If WPF becomes a first class citizen of the Xamarin ecosystem, then this should really be the first choice for cross-platform development of Xamarin applications which require a Windows app footprint. Find out more about Xamarin’s plans here. We will be prototyping to see what we can do with these frameworks soon.

Performance Improvements in SciChart WPF v5.1
Posted by Andrew on 21 February 2018 02:38 PM

SciChart WPF v5.1 will be released in the next few days. Here’s a sneak peak what we have added along with many features & bug fixe! Back in 2012 when SciChart WPF first came into existence, our main goal was to deliver High Performance, Realtime Charts to desktop applications on the Windows Presentation Foundation platform. Over the years our performance goalposts have moved. Originally we wanted to draw 100,000 points in realtime, then a million, then ten million! SciChart WPF v4 was an extremely fast & performant version of SciChart which was able to draw 10 million points (or more) for line series, a million or so for scatter series, and could comfortably draw hundreds or even thousands of series. However, our users want more! Some of our power-users are using SciChart to draw huge datasets, so as a result, we’ve undertaken work to improve the speed of our WPF Charts in certain key areas, including: Performance of Line Series when many series / few points
In SciChart v5.1 we have added a new experimental drawing mode, which applies to line series only. This mode improves the performance of line series drawing up to 4x faster than previous version(s) of SciChart.
To enable faster drawing of line series, use the following code: <s:SciChartSurface s3D:DirectXHelper.TryApplyDirectXRenderer="True"
s:PerformanceHelper.EnableExtremeDrawingManager="True">
...
</s:SciChartSurface>
PerformanceHelper.SetEnableExtremeDrawingManager(sciChartSurface, true); DirectXHelper.SetTryApplyDirectXRenderer(sciChartSurface, true);
Performance of FIFO / Scrolling series
In SciChart v5.1 we have added a new experimental set of resampling algorithms, which performs resampling in-place (does not unwrap). The result is the performance of FIFO Series is up to 4x faster than previous version(s) of SciChart. To enable faster FIFO resampling, use the following code: <s:SciChartSurface s3D:DirectXHelper.TryApplyDirectXRenderer="True"
s:PerformanceHelper.EnableExtremeResamplers="True">
...
</s:SciChartSurface>
PerformanceHelper.SetEnableExtremeResamplers(sciChartSurface, true); DirectXHelper.SetTryApplyDirectXRenderer(sciChartSurface, true);
Performance of Scatter Series with PaletteProvider (per-point colouring)
In SciChart v5.1 we have added a new series type: ExtremeScatterRenderableSeries. This series type adds an optimization which is available for DirectX only. When the optimization is enabled, points are drawn as batches and there is no performance hit when switching color dynamically in the scatter series. The new implementation is over 10x faster than the old scatter series when palette provider is enabled. (For non paletted series, the performance is the same).
To enable faster performance Scatter Series with PaletteProvider, use the following code: <s:SciChartSurface s3D:DirectXHelper.TryApplyDirectXRenderer="True">
<s:SciChartSurface.RenderableSeries>
<s:ExtremeScatterRenderableSeries x:Name="scatterSeries">
<s:ExtremeScatterRenderableSeries.PointMarker>
<s:EllipsePointMarker Width="5" Height="5"/>
</s:ExtremeScatterRenderableSeries.PointMarker>
</s:ExtremeScatterRenderableSeries>
</s:SciChartSurface.RenderableSeries>
...
</s:SciChartSurface>
DirectXHelper.SetTryApplyDirectXRenderer(sciChartSurface, true);
scatterSeries.PaletteProvider = new TestPaletteProvider(new Color[] { Colors.Red, Colors.Green, Colors.Blue ... } );E
// where ExtremePaletteProvider defined as
public class TestPaletteProvider : IExtremePointMarkerPaletteProvider
{
private readonly List<Color> _dataPointColors;
private readonly Values<Color> _colors = new Values<Color>();
public TestPaletteProvider(List<Color> dataPointColors)
{
_dataPointColors = dataPointColors;
}
public Values<Color> Colors { get { return _colors; } }
public void OnBeginSeriesDraw(IRenderableSeries rSeries)
{
var indexes = rSeries.CurrentRenderPassData.PointSeries.Indexes;
var count = indexes.Count;
_colors.Count = count;
// copy required colors from list using data point indices
for (int i = 0; i < count; i++)
{
var dataPointIndex = indexes[i];
_colors[i] = _dataPointColors[dataPointIndex];
}
}
}
Performance and accuracy of resampling large datasetsAdditional functionality has been added in SciChart v5.1. With a re-write of our resampling algorithms taking advantage of templating in C++ we now have the fastest, most accurate resampling algorithms ever, taking care of many edge cases that were reported such as handling datasets which included NaN (null points) and uneven datasets. These improvements are enabled by setting the following code in your application: <s:SciChartSurface s:PerformanceHelper.EnableExtremeResamplers="True"> ... </s:SciChartSurface> PerformanceHelper.SetEnableExtremeResamplers(sciChartSurface, true);
How Fast is SciChart’s WPF Chart?You can see our updated performance benchmark over here at How Fast is SciChart’s WPF Chart! Over the years we have worked hard to maintain and improve performance, so that SciChart can be used in Big-Data, scientific and financial applications around the world. Best regards,

Never one to rest on our laurels, we’ve been busy at work the past few weeks writing the SciChart WPF v5 Documentation. This has been released today! You can view the updated SciChart WPF v5 Documentation at https://www.scichart.com/wpf-chart-documentation What’s New in WPF v5 Documentation? MVVM Tutorials!  New Filters API Docs  3D Charts Documentation We have a new set of Tutorials on using SciChart with the MVVM API, including binding to series viewmodels, axis and annotations, updating charts in real-time and linking multiple charts and more. We have a set of documentation on using the Filters API – a brand new API in SciChart WPF v5 Documentation on the MVVM Axis API and MVVM Annotations API, both new to SciChart WPF v5. Some notes about increasing the precision of resampling using the Extreme Resamplers API. Enjoy!

SciChart WPF v5.0.0 is here!

SciChart WPF v5 is Finally Here!After what feels like a long wait, our team has finished wrapping up SciChart WPF v5.0.0 Build 10958 which is released today! Read on to find out what’s new in this exciting version of the SciChart Charting Library.
New Features (2D Charts)New Heatmap ControlsThe FastHeatmapRenderableSeries has been made obsolete, and replaced with two new controls! The FastUniformHeatmapRenderableSeries, and the FastNonUniformHeatmapRenderableSeries. These updated heatmap controls provide additional performance and features including:
Filters APIThe Filters API provides a lightweight API to allow you to create, or use custom filters with the SciChart DataSeries. Several built-in filters are included, such as:
Additional filters can be created by subclassing FilterBase. Filters wrap a DataSeries. When the original DataSeries updates, the filter triggers a recalculation and redraws the chart automatically.
Discontinuous Axis*The DiscontinuousDateTimeAxis type has been added, which acts like a DateTimeAxis (value axis), but allows skipping certain dates according to a calendar. This axis type can be used to show trading/stock charts and hide blocks of time (such as weekends, overnight trading) from the chart. It accepts a custom calendar of skip times. Two pre-programmed calendars (NYSE, LSE) are also included. This axis type may be used for non-trading systems, e.g. process management or control systems where a DateTimeAxis with hidden dates is required. In combination with the AggregationFilter type, SciChart WPF can now render Range Bars, Volume Bars, Tick Bars, Renko Bars as well as Time Based Bars in the Aggregation Filters Example. *This axis type is included in the SDK / Enterprise versions of SciChart only. | |
