A sparkline is tiny chart that helps present trends and variations associated with a measurement– such as average temperature, stock market activity, etc.–in a simple, lightweight, and condensed manner.
There are four types of sparklines (line, column, area, and win loss) which are used to show data trends.
A line sparkline identifies the patterns and trends in data such as seasonal effects, large changes, and turning points over a period of time, etc.
Column sparklines are designed to show different values of two or more subjects; vertical bars can be used to represent the different values.
An area sparkline is a line sparkline with the area between its points colored. This is primarily used when the magnitude of the trend is to be communicated rather than individual data values.
A win-loss sparkline is used to show if each value is positive, negative, or zero to visualize a win/loss scenario, such as results in games.
Markers are used to highlight data points in line and area sparklines and make these sparklines more readable.
The default color and transparency of markers can be customized.
The default size of marker can be customized to enhance readability
The color of key data points, such as first, last, high, and low points, can be highlighted and customized to denote the data usage.
The color of the first and last points of a sparkline can be customized.
The color of high and low points of a sparkline can be customized.
Range bands are used to highlight a particular region in a sparkline to show the range of safe values. By setting the minimum and maximum ranges for range band, the outliers can be easily identified.
The axis of a sparkline can be configured and customized to show the origin of sparkline data points.
