Techopedia Explains Fever Chart
Fever charts are considered important tools in statistics. When the values of variables are recorded and viewed over a long period of time, it is difficult to derive patterns or trends from plain data. However, when the same data is represented in a fever chart, it becomes easier to spot trends or patterns. For example, weather, business and the growth of insect population all exhibit certain cyclical patterns. In such cases, the variable does not typically exhibit a continuous increase or decrease, but varies depending on the time of the year and other factors such as weather or demand. With a fever chart, it is easy to spot such cyclical patterns.
There are many methods of creating fever charts. To start with, one can create simple to complex fever charts with the help of a spreadsheet program such as Microsoft Excel. At the enterprise level, highly complex and customizable fever charts are created with programming languages such as JavaScript or any other programming language made for the web. Recently, fever charts are being linked to databases that aggregate big data and powerful analytics are being shown.
