Expenses in red below, income in green above, over time on the x axis, value on y axis.

Plot a calendar in python using matplotlib. The days are drawn on a 7*52 heatmap grid, with the months clearly delineated.

« In effect, the chart becomes a rubber stamp for rendering data visually. »

Working example of a reusable chart that is re-used in space and in time (for updates). The reusable chart is the TimelineChart constructor function in timeline.js.

The key function is used to access the bound data in the circles selection to convey that the represented events are different.

Bar chart of number of events per week (week starting on a Monday). The interesting bit was how to group by week while still preserving the notion of time to be able to use months in the x axis. A clipping path was used to not show the beginning of a week where there was no data (data started on a Saturday).

Fake events were generated using this fake-event-generator.
