Overview

This application allows you to display analysis or weather data across the year grouped by day, week and month. The aim is to facilitate the visual identification of trends based on where they fit within the standard working week and seasonally across the year, which may not be as immediately obvious using other chart types. This format is also particularly well suited to the represention of annual scheduling information.

Starting on a Monday

According to ISO 8601, the international standard week starts on a Monday and finishes on a Sunday. Whilst there are cultural variations, ISO 8601 is an agreed standard that provides an unambiguous and well-defined method of representing dates and times across all countries, even those with completely different representational conventions.

In relation to building performance analysis, using this standard corresponds well with the typical international working week, in which there are likely to be differences in activity levels on weekdays (Mon to Fri) and weekends (Sat, Sun). In terms of the chart itself, it means that weekdays and weekends are naturally grouped together for purposes of both interactive selection and direct visual comparison, instead of weekends being split apart at either end of the chart.

Interesting Features

I needed to develop this type of chart as part of my annual hourly schedule editor. This app is a by-product that lets me stress test its different parameters and make sure it is flexible and robust enough to handle different types of daily data.

The following are some of this app's more interesting features:

• It can handle hourly, daily and even monthly data sets,
• It is highly customisable, allowing the manipulation of most parameters, and
• You can save charts locally as vector SVG files.
