Rectangular Block Chart

Version

Application Scenario

Rectangular block charts display the distribution of different data points in the form of rectangular blocks. The charts represent the corresponding indicator values through different colors or block sizes.

For example, you can use a rectangular block chart to display the distribution of the total dwell time of the latest access phase on different access platforms. The longer the access time, the darker the color and the larger the size of the rectangular block.

Basic Requirement

The basic requirements for rectangular block charts are as follows.

Chart Feature

1. Advantage

• Visual comparison: The charts can visually compare the values of different categories through the size or color of rectangular blocks.

2. Disadvantage

• Not suitable for continuous data: Continuous data or time series can be better displayed in a line chart.

• Space efficiency: Rectangular block charts may need larger space during the display of a large data volume.
