"I feel the need... the need for SPEED!" [Seven simple, performance-boosting tweaks for common Silverlight/WPF Charting scenarios] - Delay's Blog. No matter how fast things are, they never seem to be fast enough.
Even if we had the world's most optimized code in the Silverlight/WPF Data Visualization assembly, I bet there would still be a couple of people who wanted better performance. Unfortunately, we have don't have the world's most optimized code, and performance concerns represent one of the most common customer issues with Charting. While I wish we had the resources to commit to a few weeks of focused performance work, things just haven't panned out like that so far. Instead, I've got the next best thing: a collection of simple changes anyone can make to noticeably improve the performance of common scenarios with today's bits! To demonstrate the impact of each of these tips, I've created a new "Performance Tweaks" tab in my DataVisualizationDemos sample application. For each of the seven tips below, I list simple steps that show the performance benefit of the tip using the new sample page. Samples Environment for Microsoft Chart Controls.
You can now download Visual Studio 2010 projects that contain all the samples targeting .NET Framework 4.The samples environment for Microsoft Chart Controls for .NET Framework contains over 200 samples for both ASP.NET and Windows Forms.
The samples cover every major feature in Chart Controls for .NET Framework. They enable you to see the Chart controls in action as well as use the code as templates for your own web and windows applications. The samples environments each contains a Getting Started section to help you start using the Chart controls quickly. The samples demonstrates how to use the following features in Microsoft Chart Controls for .NET Framework: Chart Controls. The Chart controls enable you to create ASP.NET pages or Windows Forms applications with simple, intuitive, and visually compelling charts for complex statistical or financial analysis.
The top 20 data visualisation tools. One of the most common questions I get asked is how to get started with data visualisations. Beyond following blogs, you need to practise – and to practise, you need to understand the tools available. In this article, I want to introduce you to 20 different tools for creating visualisations: from simple charts to complex graphs, maps and infographics. Almost everything here is available for free, and some you have probably installed already. Advertisement Entry-level tools At the entry level, we'll be looking at unexpected uses for familiar tools. Bresenham's line algorithm. The Bresenham line algorithm is an algorithm which determines which points in an n-dimensional raster should be plotted in order to form a close approximation to a straight line between two given points.
It is commonly used to draw lines on a computer screen, as it uses only integer addition, subtraction and bit shifting, all of which are very cheap operations in standard computer architectures. It is one of the earliest algorithms developed in the field of computer graphics. OpenWPFChart library. New tools for new science. Inspiration | Features | Download | People | Acknowledgements Easy visualization of scientific data: drag, drop, filter, slide, view, zoom, share DataSet Viewer is a simple standalone menu-driven tool for quickly exploring and comparing time series, geographic distributions and other patterns within scientific data.
DataSet Viewer combines selection, filtering and slicing tools, with various chart types (scatter plots, line graphs, heat maps, as well as tables), and geographic mapping (using Bing Maps). The resulting views can be exported as images or movies, or bundled into an interactive package that be shared with colleagues. Inspiration The biological sciences are generating ever larger and more complex data sets, whether from experiments, observations, or models. Features Download. OxyPlot. A WPF Pie Chart with Data Binding Support. Download source code - 26.9 KB Contents Introduction The Windows Presentation Framework provides developers with a toolset for developing visually rich and interactive user interfaces.
Dynamic Data Display. Tutorial: Creating Charts with Real-Time Data. This example implements a workflow that calculates a random walk and displays the generated values.
The calculation is run on a background thread, so the approach is suitable for more complicated calculations that take some time to complete. The example uses the FastLine chart type. Built-in Charting Controls (VS 2010 and .NET 4 Series) [In addition to blogging, I am also now using Twitter for quick updates and to share links.
Follow me at: twitter.com/scottgu] This is the fifteenth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. Today’s post covers a nice addition to ASP.NET and Windows Forms with .NET 4 - built-in charting control support. Www.dotnet-france.com/Documents/Win/35/Microsoft Chart Controls.pdf. Dynamic Data Display. New tools for new science. Inspiration | Features | Try online | Download | Case studies | People | Acknowlwdgements Visualize your data over the web and add complex dynamic graphs and maps to your web applications Dynamic Data Display facilitates the interactive visualization of dynamic data within your Silverlight application.
It contains a set of Silverlight controls for creating line graphs, bubble charts, heat maps and other complex 2D plots. Dynamic Data Display also integrates with the Bing Maps control to show data on a geographic map in latitude/longitude coordinates. The controls are compatible with most popular development tools like Expression Blend and Visual Studio. Inspiration Developing scientific software for Microsoft Silverlight has certain attractive aspects: applications run on both Windows and Macs, browser-based deployment is exceptionally lightweight, and yet the underlying algorithms can be written in modern programming languages such as C#, F# or Python.

Polyline Simplification. Table of Contents Introduction Polyline simplification is the process of reducing the resolution of a polyline. Ramer–Douglas–Peucker algorithm. The Ramer–Douglas–Peucker algorithm (RDP) is an algorithm for reducing the number of points in a curve that is approximated by a series of points. The initial form of the algorithm was independently suggested in 1972 by Urs Ramer and 1973 by David Douglas and Thomas Peucker and several others in the following decade. This algorithm is also known under the names Douglas–Peucker algorithm, iterative end-point fit algorithm and split-and-merge algorithm.
Idea The purpose of the algorithm is, given a curve composed of line segments, to find a similar curve with fewer points. Memory Management for Large Data Sets - LabVIEW 2011 Help. LabVIEW automatically handles memory allocation. Since this process is automatic, LabVIEW must take precautions to handle the data safely. This means that LabVIEW copies data frequently. If the program deals with large sets of data, large and frequent data copies may lead to an out of memory error. Use the following guidelines to avoid memory problems and optimize the program to handle large data sets. Reducing Copies of Large Data Sets. System.Windows.Media, espace de noms () High Performance WPF Silverlight Charts. Real-time Line charts with WPF and Dynamic Data Display. When logging datas from sensors it’s important to visualize them with a powerful real-time chart. In automation especially it’s common to analyze processes with the help of charts to predict and regulate the process.
One of the most powerful charts (and for many the best) is Dynamic Data Display, an open source library for WPF. This library is good because of the many features (panning, zooming, saving screenshots etc…) and because it renders fast with huge collections of points.
