It’s been a while since we’ve shipped a WPF release, as we are busy working on a number of exciting projects! However today we are pleased to announce that an important stability update for SciChart WPF: v4.2.3.10185 has been released. What’s New in SciChart WPF v4.2.3.10185?Lots and lots of bugs fixed! It is recommended for all users of SciChart WPF v4.x to update to the latest version, which should be a drop in replacement. Critical Bugs (Crash or Memory Leak) Fixed
Minor Improvements
Where to Get It?SciChart WPF v4.2.3.10185 is available from the usual channels.
Please ensure you uninstall previous version(s) of SciChart before installing v4.2.3 as this can prevent some issues in the upgrade process! What’s Coming Soon?We are still working hard on a massive release of SciChart iOS & Android v2, which will include Xamarin.iOS and Xamarin.Android support. You can access early BETA’s of all three via our public Github repositories: Each of the above repositories pulls binaries for SciChart iOS/Android/Xamarin v2 from Cocoapods (iOS), Maven (Android) and NuGet (Xamarin). Full build instructions are included in the Readme.md in the above repositories. SciChart WPF Development in progressWe are also still working on a major update to SciChart WPF. This will feature a number of new 2D+3D Chart types as well as improvements to speed, stability and API for our WPF customerbase. We have delayed releasing this since we want to get it right, and we have so many users using SciChart WPF v4 with great success, that there is no significant rush to get to market and we want to ensure when we do deliver, it will be super-awesome. If you want to preview SciChart WPF v5 you can do so, again via a public Github repository, which also pulls assemblies from NuGet.
Best regards,

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 containsSciChart WPF Examples Source Code
SciChart WPF Tutorials
SciChart WPF Examples Sandbox
Cloning the Repository and Building the Source
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.
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 v5WPF Radar ChartFrom 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!
You can see an example of use here. WPF Discontinuous DateTime AxisIn 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.
You can see an example of use here. Uniform Heatmap TypeThe 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.
You can see an example of use here Non-Uniform Heatmap TypeStill 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 | |

DirectX WPF Chart Compatibility
Posted by Andrew on 17 January 2017 10:40 AM

Once we move away from the happy, safe world of .NET and into unmanaged code, we need to take a few extra steps to ensure compatibility! This post aims to address compatibility issues with using the Direct3D10RenderSurface, a premium add-on to SciChart High Performance WPF Charts. Direct3D10RenderSurface System RequirementsOperating System RequirementsThe SciChart Direct3D10RenderSurface requires Windows Vista, 7, 8, 8.1 or higher. Hardware RequirementsThe SciChart Direct3D10RenderSurface requires a DirectX10 compatible GPU.
PrerequisitesThe SciChart Direct3D10Renderer has a dependency on D3DX9_43.dll and D3DX10_43.dll.
Deploying your SciChart Application with the Direct3D10RenderSurfaceDeveloper PCs and End-User PCs have the same system requirements to run the SciChart DirectX Renderer. To ensure your SciChart application can use the Direct3D10RenderSurface wherever available, and downgrade to software renderer when not available, please follow these steps: 1. Enable the DirectX RendererFollow the example at Easy Fallback from DirectX to Software Rendering without code behind: <SciChartSurface DirectXHelper.TryApplyDirectXRenderer="True"> ... </SciChartSurface> 2. Distribute SharpDX 2.6.2 with your ApplicationThe Direct3D10RenderSurface also has a dependency on SharpDX v2.6.3 (a Managed Wrapper for DirectX, licensed under the MIT License). Please make sure the following DLLs are in your output directory (where your application exe resides) when deploying applications with DirectX. SharpDX is also available on NuGet.
3. Ensure the DirectX Runtime is installed on End-User PCsAll End-User PCs must have the DirectX Runtime installed. The package is included in the SciChart v3.2.4 or later installation directory at %InstallDir%\Prerequisites\DirectX. You will need to include the DirectX Prerequisites and install DXSetup.exe on end-user PCs when you deploy your application*. To silently install the DirectX Runtime on end-user PC’s, please run the following command line in your application deployment process:
*Microsoft permits you to redistribute the above files with your end-user applications royalty free. The licensing terms for DXSetup can be found in the licensing agreement of the DirectX End-User Runtimes (June 2010) Frequently Asked QuestionsQ: How can I check at runtime if the DirectX renderer is supported on my PC?A: You can use the Direct3D10CompatibilityHelper class! Usage: /// <summary>
/// A helper class which can be used to detect if the Direct3D10 enhancements to SciChart can run on the current hardware & operating system
/// </summary>
public static class Direct3D10CompatibilityHelper
{
/// <summary>
/// Supported operating systems include Windows Vista, Windows 7, Windows 8, 8.1 and up. Windows XP, 2000, 2003 are not supported.
/// </summary>
public static bool IsSupportedOperatingSystem { get; }
/// <summary>
/// Determines if the DirectX10 Runtime Libraries can be found in the C:\Windows\System32 and C:\Windows\SysWow64 folders. If the libraries are not present, we recommend
/// installing the DirectX Runtime from %SciChart Install Dir%/Prerequisites/DirectX.
/// This installs platform specific libraries (x86, x64) and SciChart dynamically chooses the correct DirectX version at runtime
/// </summary>
public static bool HasDirectX10RuntimeInstalled { get; }
/// <summary>
/// Determines if the current GPU supports DirectX10 or later
/// </summary>
public static bool HasDirectX10CapableGpu { get; }
/// <summary>
/// Determines if the current hardware & software configuration fully supports DirectX10 or later
/// </summary>
public static bool SupportsDirectX10 { get { return IsSupportedOperatingSystem && HasDirectX10RuntimeInstalled && HasDirectX10CapableGpu; } }
}
Q: Do I have to install the DirectX Runtime on every End-User PC?A: SciChart actually only requires D3DX9_43.dll and D3DX10_43.dll The way to deploy them is by including DXSetup.exe and related files (found in the %SciChartInstallDir%\Prerequisites\DirectX folder) with your application deployment. You can run DXSetup on end-user PCs by calling the command line
Please note: The licensing terms for the DirectX Runtime restrict you from packaging or embedding the required DLLs with your application, but allows distributing DXSetup and associated files in the %SciChartInstallDir%/Prerequisites/DirectX folder. You must run the DXSetup installer on end-user PCs to remain compliant with Microsofts terms. Q: Does the DirectX Renderer Work over Remote Desktop?A: We use D3DImage, which is a Microsoft control that allows sharing of DirectX content with WPF, avoiding airspace issues and allowing fast interop between WPF’s DirectX9 and DirectX10 rendering. Unfortunately D3DImage has a bug, a nasty one. It won’t work over remote desktop if your application is .NET4.0! It will work over Remote Desktop on .NET4.5 and above. Since SciChart v4 we have developed a workaround where SciChart DirectX will now work over remote desktop. This is automatic and no changes need to be applied to your code. Q: I am experiencing flicker with DirectX in my applicationPlease see this FAQ which talks about how to resolve the problem of Flickering Charts in SciChart. Q: How much faster is the DirectX Renderer than the Software Renderer?A: The answer will depend on your exact hardware, software configuration and what you are doing with the chart. In our tests we found the DirectX Renderer to be on average 3.92x faster than the High Speed software renderer, and with superior visual quality (sub-pixel antialiasing). Not bad for a drop-in upgrade!
Got Feedback?DirectX is a big part of our future, so we want to make this work for you. If you experience compatibility issues or other problems using the DirectX renderer, then please do get in contact with your feedback. We would love to be of assistance.

Requirements for 3D Surface Mesh Charts
Posted by Andrew on 24 November 2016 05:47 PM
|

Hey everyone! Even though the release of SciChart WPF v4.2 is barely a day old(!) we are already hard at work on v4.3, where we intend to add some new features for SciChart WPF 3D Charts as well as several 2D Chart features. We want to get some information from you, our userbase, as to what requirements are most important to you. We also need to ask you a few questions about how you would expect correct usage of the 3D Chart. Features Planned for v4.3We are planning the following features for v4.3 of SciChart WPF and we need your feedback on them. Some questions and explanation are found below.
SC3D-218 Contours on MeshesWe can add contours on surface plots quite easily. Something like this:
This is quite easy to do, but we would like to know from you if (a) it is important, (b) you need to be able to configure the contour colours dynamically (per contour, as opposed to one colour for all), (c) whether you have any special requirements for placing contours, or if you would like SciChart to choose and (d) any other comments or suggestions for the API as we build it. Can you contact us if this feature is important to you? Your input into the requirements would be greatly appreciated. SC3D-336 Support for Nulls in Surface MeshesA number of users have asked for nulls (transparent cells) in surface meshes. This sounds easy on the surface, but it isn’t … Nevertheless we want to deliver it. We do have some questions though. Given a surface mesh with 8×8 data values, we end up with something like this (below). The data-points are shown by orange dots. The cells are the squares next to the dots.  8×8 Surface Mesh. Data-values are marked as orange points As you can see, cell colour is specified by interpolating the four points surrounding a cell. For example, the cell in the top right has a data-value of Y=1 so it should be red, but it isn’t, it’s yellow, because it has two other edges which are only at Y=0.5. Now if a user wants to specify a cell as transparent, for example the cell at X=1, Z=6, them you end up with this:  When one data-point is null at X=1,Z=6, four cells become transparent. Now this obviously isn’t ideal. We thought about how to solve this. We could allow you to specify a separate texture for the mask to ‘null’ certain cells, however you will notice that there are 8×8 data-points in the mesh, but only 7×7 cells, so the texture size doesn’t actually match the data size. This would allow you to mask out certain cells but it would also give you a clunky API and raise questions of accuracy because of the mismatch of sizes. Another way is we could change how we are drawing the cell textures. We could offset the texture so that each square in the texture surrounds the data-point, for example:  Proposed solution: offsetting cell positions so the centre of the cell is over the data-point This would be a nice solution except it raises two problems.
We invite your comment/feedback on this proposed solution and whether it seems correct. It is very important to us that our scientific WPF Charts are both intuitive and accurate. SC3D-337 Uneven Spacing of Surface Mesh Data-PointsSeveral users have requested that we allow uneven spacing of surface mesh data-points. However, we have a question. Which sort of spacing are you expecting, (A) or (B)?  (A) Uneven spacing of mesh points with each point in a row, column the same as the other points  (B) Uneven spacing of mesh points with decoupled placement of points SC3D-338 Waterfall Charts 3DIn SciChart WPF v4.3 we intend to add Waterfall Charts 3D. For clarification, we intend to create a hardware-accelerated version of our WPF Waterfall Chart Example using SciChart3D:  The SciChart WPF Waterfall Chart is simulated using 2D Charts If we do this, we will likely bind it to our UniformGridDataSeries3D type. This means the data-source will be a 2-dimensional Double[][] array of Y-values only. But what sort of requirements do you need for this chart type? Do you need for example:
We’re assuming you need realtime performance & being able to scroll in the Z-direction (time) … SC3D-326 Virtualization of Large SurfacesThe current limit for the size of the 3D Surface Mesh chart is limited by the maximum texture size on your GPU, which in most cases is 4096*4096 and on some GPUs is larger, up to 16k * 16k. Some customers have contacted us and asked for larger surface sizes, but we would just like to know how many so that we can prioritise this complex piece of work. Finally..Those are all the questions we have about SciChart 3D Surface Mesh for now. If you are a current customer of SciChart WPF 3D, or you are considering to purchase this software, please get in contact with your feedback. It is extremely valuable that we build software that you actually want to use and meets your requirements! Best regards,
