02 Aug, 2013Dynamic Charts in WPF
There are a plethora of WPF charting solutions out there, both commercial and open source. I have tried quite a few but have yet to find one that is capable of handling highly dynamic data whilst also providing useful customisations such as centered axis or generating polar diagrams. I do most of my dynamic charts in OpenGL but labelling axis and data points using textured fonts lacks some of the polish I have seen in many WPF-based solutions. Thus I thought that, for my Windows apps, I would try porting my OpenGL chart library to WPF.
01 Nov, 2009Graph - Robustness Calculator
A significant problem in the performance analysis of buildings is trying to understand hugely complex data sets that often results from the investigative process. These types of analysis are usually focused on the potential effect of different design parameters on the performance criteria we are designing to meet. The type of graph described here provides a simple means of interactively investigating and visualising complex relationships that may exist within a large number of calculation runs.
05 Aug, 2009Graph - Annual Temperatures (Google)
The graph is one of my experiments with Google's Visualisation API as a possible means of interactive web-based data presentation. It's an implementation of an annotated time line graph that Google originally developed for showing stock exchange data - used here to show annual hourly air temperature values. It has to process a whole year's worth of hourly temperature data for San Francisco, so it can take a little while for the graph to first appear.
27 Jul, 2009Graph - Annual Temperatures (Java)
This is an experiment with the use of Java applets to provide highly interactive charts and graphs embedded within a web page. It is just an example so the data it shows is not hugely meaningful - in this case a set of annual hourly air temperature values. However, it is an opportunity to play with my primitive attempt at an interactive and intuitive date range control. This control sits at the bottom of the chart and provides a means for selecting a date range for the values shown.
