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 Controls

The 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:

• PaletteProvider supported in Heatmap (override cell color)
• Point Metadata supported in Heatmap (tag cell data)
• Contours
• Support for massive heatmaps: 10k * 10k!
• Performance: New Heatmap series up to 10x faster when DirectX Enabled.

Filters API

The 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:

• MovingAverageFilter: Applies an N-length Moving Average to a DataSeries
• LowPassFilter: Applies a Butterworth Low-pass filter to a DataSeries
• ScaleFilter: Scale a DataSeries by a scalar value
• OffsetFilter: Offset a DataSeries by a scalar value
• LinearTrendlineFilter: Generates a Linear Trendline fit for a DataSeries
• PolynomialFilter: Generates an N-order polynomial fit for a DataSeies
• SplineInterpolationFilter – interpolates a dataseries using a spline tension
• AggregationFilter – aggregates time based OHLC data into Range or Volume bars

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.

Market Profile Series Type*

A new series type which renders a Market Profile: a histogram between Candlesticks to visualize trading volume data.

*This series type is included in the SDK / Enterprise versions of SciChart only.

Radar Chart

A Radar Chart type has been added, which allows customised axis to display relationships between datasets.

Extreme Resamplers & Performance Improvements

Our resampler algorithms have been re-written using C++ for enhanced resolution, speed and efficiency. Long standing problems solved include:

• Performance problem when resampling FIFO series / avoiding copy operation for First-in-first-out buffers.
• Resampling accuracy improved when the data-set includes NaN gaps
• Resampling accuracy improved when the data-set is unevenly spaced in X
• Resampling accuracy flag BaseRenderableSeries.ResamplingPrecision allows setting of resolution for crisper, higher res charts.

Multitouch Improvements

Multitouch has been improved in SciChart 2D Charts. The PinchZoomModifier now works flawlessly with the ZoomPanModifier. Accuracy and precision of MultiTouch has been improved.

SciChart 3D Charts get PinchZoomModifier3D.

MVVM Improvements

SciChart 2D Charts have new MVVM APIs. AxisBinding and AnnotationsBinding MarkupExtensions now complement our SeriesBinding API for MVVM developers.

SciChart 3D Charts get SeriesBinding3D and supports AxisBinding.

New Features (3D Charts)

Non-uniform 3D Mesh Chart

SurfaceMeshRenderableSeries3D now accepts a NonUniformGridDataSeries3D as well as a UniformGridDataSeries3D. Spacing data is provided for the X-Z plane allowing the surface mesh to be non-uniformly spaced.

Contours (3D Charts)

3D Surface mesh charts now support contours, wireframe, or both contours and wireframe. See our examples to see how this feature is applied.

3D Object Loading *.obj (3D Charts)

Textured 3D Objects may be added to a 3D Chart at specifix XYZ format. SciChart accepts the *.obj file format, or Obj file streamed from embedded resource.

Waterfall & Realtime Waterfall (3D Charts)

A new 3D Chart Type called Waterfall3D has been added to the SciChart 3D library. This renders a UniformGridDataSeries3D as a series of waterfall slices. Waterfall charts support realtime scrolling & updating, as well as optional slice thickness, point-markers, selection and more.

PaletteProvider in SurfaceMesh

We’ve added the feature of nulls (empty cells) in surface mesh, as well as custom cell color override for the 3D Surface Mesh chart, by adding support for the PaletteProvider API.

3D Chart Visual & Usability Improvements

Multiple improvements have been made to the 3D Charts APIs, visuals and usabilty, including:

• Added PinchZoomModifier3D for zooming and orbit of 3D Charts on touch screens.
• Huge improvement to Font Rendering quality and labels positioning in 3D Charts.
• Added cell hardness lighting for Surface Meshes.
• Improved visuals on a 4K Screen.

Performance Enhancements to 3D Charts

Several 3D Chart types have been optimized for larger datasets & higher throughput in realtime charting situations.

Optimizations include:

• Performance Improvements to ScatterRenderableSeries3D – up to 10x faster – supporting millions of scatter points in 3D!
• Performance improvements to PointLineRenderableSeries3D – up to 10x faster – supporting millions of lines in 3D!
• Large Surface Mesh support: Virtualized surface meshes. NxM size limited only by video memory

Other Improvements

The minimum requirement for SciChart WPF v5 is now .NET4.5. From version 5 onward, we will no longer support .NET4.0. This is inline with Microsoft support guidelines, and allows us to use the later versions of SharpDX.

• .NET4.6, .NET 4.7 are now fully as NuGet packages.
• SciChart.Drawing.DirectX (2D DirectX Charts) now support SharpDX v4.
• SciChart.Drawing.DirectX (2D DirectX Charts) and 3D Charts now support DirectX11/9 instead of DirectX10/9. This results in improved compatibility with older GPU hardware.
• We have removed the dependency on obsolete/outdated DirectX June 2010 SDK
• We have removed the dependency on Visual C++ Runtime – SciChart now ‘just works’ on client PCs with .NET4.5 or above.

What did we miss / but is coming soon?

We decided to release now, as it has been a while since our last major update. Some features got missed from the release, but are in progress. These include:

• Extreme / Faster Scatter Series type with coloring per-point. ETA: ~3 weeks
• UWP Universal Windows Platform Chart component: ETA ~2 months.

Pricing and Licensing

• For existing customers with active support subscriptions, SciChart v5 is FREE (no charge).

The post SciChart WPF v4.2.3 Build 10185 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

In the past few weeks, we have been working on shaping our product and vision for SciChart WPF, with the help of feedback from our userbase and potential customers. One of the requests which you have asked for is the ability to have the SciChart WPF Examples source code available *outside the installer*. As a result, we have taken the step to setup automatic publishing of the SciChart WPF Examples Suite to Github, referencing the SciChart WPF DLLs from NuGet. We are hoping that this will be a powerful resource which will enable our users to fall into the pit of success when using SciChart!

What is in SciChart WPF Examples Repository?

The SciChart WPF Examples Repository can be found on Github under the ABTSoftware organization. This is a public repository with an open source License. You are free to clone it using Git or SVN clients, download the code, and use anything in it for commercial or open source purposes.

The repository contains

SciChart WPF Examples Source Code

• The full source code for the SciChart WPF v4.x Examples Suite
• The full source code for the SciChart WPF v5.x Examples Suite (BETA)

SciChart WPF Tutorials

• The full source code for the SciChart WPF Tutorials, which were published last month on our website

SciChart WPF Examples Sandbox

• A sandbox area to create examples for users who ask for them.
• Currently there is one example published: The Custom Modifier Sandbox

Cloning the Repository and Building the Source

• You can clone the repository with Git, Tortoise SVN client, or download a zip.
• You will need Visual Studio 2010, 2012, 2013 or 2015 installed.
• You will need to setup the NuGet feed as per our instructions ‘Getting Started with NuGet’
• After that just build and run. The SciChart.Wpf.Examples will get all packages from NuGet and will build and run!

Wait, What? SciChart Examples v5?

That’s right! You heard correctly. We are now publishing an Early Access Preview of the the SciChart WPF Examples v5 to the Github repository, along side SciChart WPF v5 BETA to our abtsoftware-bleedig-edge (BETA) NuGet Feed.

SciChart WPF v5 IS A VERY EARLY BETA. This version of SciChart is very much in flux. We wanted to be able to showcase what we have been working on as well as give some of our customers early access to the next major version of SciChart, which is currently on schedule to be released in May.

WPF v5 Burndown Chart as of March 2016. Expected delivery in May 2016

If you want to see what we’re doing for SciChart WPF v5, head on over to our Public Issue Tracker where you can see the sprints, the tasks in progress and our statuses. ‘Delivered’ state means published to NuGet & Github!

New Features coming soon to SciChart WPF v5

WPF Radar Chart

From one of the surveys we learned that  Radar Charts are important to many users.

This 2D Chart will be added to SciChart WPF v 5 to allow displaying radars with customizable axes and selectable series or data-points. This chart type has been built from the ground up using our fast 2D drawing technology and looks great!

The WPF Radar Chart type allows unlimited, configurable ‘Radar Axis’ with data series as Polygons, Point-Markers or Lines. Tooltips and Legends and theming come as standard

You can see an example of use here.

WPF Discontinuous DateTime Axis

In WPF v5 new DiscontinuousDateTimeAxis type is going to be introduced. This is a special axis type, specifically for financial / trading charts, which will allow you to skip ranges (overnight, weekend). It will support series with differing lengths for the first time in trading charts. This opens the possibility of all sorts of indicators and filtering techniques previously impossible with SciChart. It will allow you to use Range, Tick, Volume or Time based bars. It preserves the position on Annotations on time-frame changes. It allows showing/hiding of overnight trading on exchanges with extended trading data.

The DiscontinuousDateTimeAxis type allows Volume, Range, Price and Tick Bars as well as a calendar for skipping overnight segments/weekends for true support for financial stock charts.

You can see an example of use here.

Uniform Heatmap Type

The heatmap type is undergoing radical transformation. We have a new FastUniformHeatmapRenderableSeries. This is up to 10x faster than the existing FastHeatmapRenderableSeries for the case where cells are uniformly spaced and supports the PaletteProvider API. This works best with DirectX.

The Uniform heat map type has been heavily optimised, now yielding up to 10x faster rendering when compared to v4.x FastHeatmapRenderableSeries

You can see an example of use here

Non-Uniform Heatmap Type

Still in progress, we have a Non-Uniform heatmap type which will supercede the existing FastHeatmapRenderableSeries. This fixes issues where the Y cells don’t match the spacing provided by the user. We also hope it will be faster and more flexible than the existing FastHeatmapRenderableSeries. Still a work in progress Read more »

We are pleased to announce the release of SciChart v4.2.2 Build 9777. This is a minor update which contains many critical bug fixes and minor improvements. It is strongly advised for users of SciChart v4.x to upgrade to this version, which is a drop-in replacement.

We’re committed to providing our customers with the best experience possible, and as a result, we continue to update and improve our popular WPF Charts components!
