I haven’t updated this blog for a while. I am working on one Matlab project right now. It is kind of difficult for me to work with Matlab and Mathematica at the same time.
There is an interesting post Charting time series as calendar heat maps in R. The original idea from SAS Analysis of airline performance. I create a simple version in Mathematica. The tricky part is to generate the background grid.
The code I use is from an old tutorial of Making a Calendar. For each month, the boundary is defined by 8 points, marked out by darker line. The monthly grids are shifted to the right positions to form a yearly grid. Once you figure out this part, the rest is just straightforward.
I use the stock as the example, this is actually not the best data set for this type of visualization.
Download the file calendarheatmap.nb for the detail.
