SciChart WPF, Xamarin.iOS, Xamarin.Android now listed on nuget.org
Posted by Andrew on 19 October 2018 06:50 PM

For years we’ve operated a private NuGet feed for our libraries in SciChart, however recently we’ve taken the step to publish official releases to nuget.org as well.

Version 5.2.0.11680 has been published to nuget.org and the following packages are now available.

In future we will continue to publish nightly builds and alpha/beta builds to our abtsoftware-bleeding-edge feed, as well as official builds to our abtsoftware feed, but stable builds which have passed testing for official releases will also be mirrored to nuget.org.

Happy coding!

Best regards,
Andrew

SciChart iOS /Android / Xamarin v2.2.1 released!
Posted by Julia Skorobogata on 18 October 2018 11:42 AM

We are really excited to announce, that SciChart iOS/ Android / Xamarin v2.2.1 is released! 

What’s New in SciChart iOS /Android /Xamarin v 2.2.1?

There is a large number of improvements and bug fixes made in SciChart iOS/ Android / Xamarin v2.2.1. We have made many improvements and bug fixes, major memory leaks have been fixed. It is recommended for all users of SciChart v2.1 to update to the latest version! Please see more information below:

Changes:
  • Made SCIChartSurfaceProtocol conform to SCIChartControllerProtocol
  • Logarithmic axis zoom extents is fixed by SCILogarithmicVisibleRangeAnimator
Bug Fixes:
  • SCIOS-626: Fixed HorizintalLineAnnotation and VerticallLineAnnotation are not clipped by axes and are drawn over them
  • SCIOS-642: Fixed issue with on resize of the SCIChartSurface, lay out the axis labels
  • SCIOS-637: refactored internal scroll and removed velocityValue from improper places, fixed crash caused by SCILogarithmicDoubleCoordinateCalculator not having implemented getVelocityValueFrom
  • SCIOS-672: Fixed chart sync crash (EOG) – caused by TooltipShowOnTouch
  • SCIOS-596: Fixed Error during rendering of the first point when ifDigitalLine = true
  • Fixed major memory leaks in SciRenderable series
  • SC_DROID-558: added check to prevent exception during generation of minor ticks if there are no major ticks
  • SCIOS-682: Fixed iOS annotations seem to update independently from the data series
  • SC_DROID-562: Fixed memory leak in SpritePointMarker when textures were constantly recreated and never properly disposed because of wrong texture hash
  • SC_DROID-564: Fixed incorrect drawing of axis tick label – because StaticLayout had not enough space to fit label in one string so some labels were drawn as two lines of text;
  • SC_DROID-566: Fixed some logcat errors when OpenGL code was called without OpenGL context
  • Fixed SCIOS-687 – surface.Annotations.Clear() doesn’t clear all annotation from surface.
  • SC_DROID-568: Fixed exception because of how onSurfaceCreated() is implemented in GlSurfaceView ; refactored OpenGL renderer to avoid exception because of missing native memory chunk and made it resizable; also moved OpenGL programs creation so they are created only once
  • Fixed SCICustomAnnotation position in chart wrong
  • Fixed SCIXAxisDragModifier stopped working
  • Fixed SCILegendModifier: SCIDefaultLegendItem cell ambiguous width
  • Fixed text annotation formatting
  • Fixed exception if enable debug prints for CubicSpline
Improvements:
  • SC_DROID-566: improving OpenGL start up time – changed GLProgram implementation and made it lazy so we don’t initialize all shaders at once when render surface created
  • SC_DROID-565: added additional render pass data locks to ensure that it won’t be changed from another thread when applying transformation
  • Added default style values for PieSegment; added some common methods for PieSegmentBuilder
  • SC_DROID-563: rewritten GLTextureView rendering from scratch – now it uses Handler + Choreographer to schedule redrawing of render surface when VSync occurs in Android
  • Made custom annotations to support AnchorPoint alignment
  • SC_DROID-578: added propagating of listeners to child series for StackedSeriesCollectionBase
  • SC_DROID-561: added synchronized wrapper for SimpleDateFormat to prevent exception when same instance is accessed from different threads, applied the same approach to prevent possible exceptions when using DecimalFormat

SciChart WPF v5.2.0 Released!
Posted by Julia Skorobogata on 18 October 2018 09:41 AM

We are pleased to announce the release of SciChart v5.2.0. Build 11680 . This is a new version which includes new features and big number of  bug fixes and improvements. It is strongly advised for users of SciChart v5.x to upgrade to this version, which is a drop-in replacement. 

What’s New in SciChart WPF v5.2.o?

Breaking changes 

There are some breaking changes, that will affect users of SciChart.DirectX, Custom Themes and AnnotationCreationModifierMVVM. Please read on. To the rest of the users this version is backward compatible.

  1. users of SciChart.DirectX will now need to update SharpDX to v4.2.0
  2. users who have custom themes will need to add the following three theme keys to their Theme Resource dictionary with color values of their choice:
    <!– 3DChart Specific values –>
    <Color x:Key=”PlaneBorderColor”>#FF333333</Color>
    <Color x:Key=”AxisPlaneBackgroundFill”>Transparent</Color>
    <Color x:Key=”Axis3DBandsFill”>#E1202123</Color>
    
  3. EffectManager.Instance.EnableDropShadows has been made obsolete, to solve a memory leak caused by WPF {x:Static} MarkupExtension binding. This property is now simply EffectManager.EnableDropShadows. Binding to this property may be achieved through the .NET 4.5 Static Property binding mechanism.
  4. AnnotationCreationModifierMVVM.AnnotationType is changed to – AnnotationCreationModifierMVVM.AnnotationViewModelType and AnnotationCreationModifierMVVM.AnnotationsColection to – AnnotationCreationModifierMVVM.AnnotationViewModelsCollection.

 

WPF New Chart Type: Free Surface Mesh 3D

The Free Surface 3D Chart types are a set of 3D Charts that represent the data by plotting the surface in a custom shape in 3D space. The Free Surface 3D Chart types allows to plot both types of charts that constrained to its basic 3D primitive and unconstrained. In other words it allows you to plot charts of all kinds of shapes, including Sphere, Cylinder, Disc and free-form mesh shapes.

Please this chart type examples below:

This chart type allows customization of a chart by overlaying heightmap, colormap (palette) and contours.

scichart wpf 3d chart example of ellipsoid 3d chart scichart wpf 3d chart example of closed mesh chart scichart wpf 3d chart example of disk or polar mesh 3d chart scichart wpf 3d chart example of cylindroid 3d mesh chart

  • The 3D FreeSurfaceRenderableSeries3Dcan be rendered in realtime as well. The Free Surface Mesh colors and palette can be udpated by supplying a MeshColorPalette.

Many mesh options are available such as Wireframe, SolidMesh, Solid with Wireframe, and many paletting options such as Solid Cells, Interpolated Cells and Textured.

Please see an example below and read documentation for  SciChart WPF Realtime 3D Geoid:

Coming Soon to SciChart Q3/Q4 2018
Posted by Julia Skorobogata on 25 July 2018 01:08 PM

We’ve been quietly working away on a few projects for the past few months and wanted to give you an update to show you where SciChart will be going in the near future.

What’s Coming Soon to SciChart WPF?

SciChart WPF remains our flagship product and drives a lot of development, alongside tech support & maintenance (we have answered 692 support tickets for SciChart WPF and released 166 Nightly builds in the past year alone). We are still developing this product adding new features as our userbase requests and also features that are in strong demand.

Some of these are nearly ready for release and are listed below.

WPF New Chart Type: Free Surface Mesh 3D

A new Free Surface Mesh 3D feature will be presented in the upcoming release which will be SciChart WPF v5.2 (Q3 2018).

Free Surface Mesh 3D is a set of 3D charts that plot a surface mesh in 3D space. This chart type allows plotting closed objects in 3D that are not restricted by data laying down in the XZ plane. The charts can render different types of data including ellipsoid, cylinder, polar and even custom free surface mesh data in 3D. Please see the preview of the examples below:

scichart-surface-mesh-3D-custom-free-surface-mesh-data

Free Surface Mesh 3D with custom data

scichart-surface-mesh-3D-cylinder-data

Free Surface Mesh 3D with cylinder data

scichart-surface-mesh-3D-polar-data

Free Surface Mesh 3D with polar data

scichart-surface-mesh-3D-ellipsoid-data

Free Surface Mesh 3D with ellipsoid data

WPF New Feature: WPF Polar chart 3D

One of the chart types listed above is a 3D Polar Chart type, which allows for a flat disk with optional hole in the center defined by an equation and 2D array of data, contours, and paletted similar to a heatmap or surface-mesh chart. This chart type can be used in 3D mode or when an orthogonal overhead camera is presented, as a 2D Chart.

All new 3D Chart types will be made available to all customers of SciChart WPF SDK Professional, SDK Enterprise and 3D Professional who are in support subscription, free of charge. 

WPF New Feature: Drawing tools and Technical Indicators for trading applications

SciChart is widely used in trading and financial applications by our customers. Since a number of customers approached us to ask for these tools to be built, we have decided to make a step forward with a set of drawing tools for different patterns in trading.

The next release is expecting to bring a number of new annotation types to be used in trading systems, including:

  • Elliott Wave pattern
  • XABCD (Gartley / Bat / Harmonic polygon shapes) drawing
  • Head and Shoulders Pattern
  • Andrew’s Pitch Fork
  • Fibonacci Retracement
  • Fibonacci Extension
  • Also, we will be adding free brush style drawing to mark up the chart.

All of the following can be created programmatically, on user click, edited & dragged about, styled and persisted.

Please see some examples below:

scichart-elliott-wave-pattern-trading-tool

Elliott Wave Pattern, Trading Tools

scichart-xabcd-pattern-trading-tool

XABCD Pattern, Trading Tools

scichart-head-and-shoulders-pattern-trading-tool

Head and Shoulders Pattern, Trading tools

scichart-pitch-fork-pattern-trading-tools

Pitch Fork Pattern, Trading Tools

scichart-fibonacci-retracement-trading-tool

Fibonacci Retracement Trading Tool

scichart-fibonacci-retracement-extension-trading-tool

Fibonacci Retracement Extension Trading Tool

scichart-free-brush-drawing-trading-tools

Free Brush Drawing, Trading Tools

All new drawing tools will be in the SciChart.DrawingTools.dll package and will be made available to all customers of SciChart WPF SDK Professional, SDK Enterprise and 2D Enterprise who are in support subscription, free of charge. These drawing tools will not be available to SciChart WPF 2D Professional customers. 

What’s next in SciChart iOS / Android / Xamarin?

SciChart iOS & Android has been moving along with some progress to support latest SDKs but behind the curtain we are working on our big vision of having 2D & 3D Charts available on all native platforms, including Windows, Mac OSX, iOS, Android and with Xamarin & Xamarin Forms support.

Our next big piece of work is to bring 3D Charts to iOS & Android devices, which we have been working on quietly for the past year
