In preparation for another round of Envato screencasts, I’ve been messing around with the new Charting API that comes with ExtJS 4. For this project, I wanted to show how you can filter a grid full of data and have it change the data in the pie chart. Unfortunately, I soon discovered that pie charts (or rather, charts in general) and data grids take two different types of data.

Google has a habit of making really cool API’s to do really cool things. They also have a habit of making those API’s complicated and hard to memorize due to the overwhelming amount of parameters and commands that you can use to perform a given task. My programming goal for this week was to begin work on a library that would allow me to quickly and easily generate Google Image Charts as well as switch a chart from one type to another with minimal recoding. While I wasn’t able to complete the task by the time I needed to start writing about it, I was able to get a solid enough start to feel comfortable sharing what I have so far.
