Bar Chart

A bar chart uses vertical or horizontal bars to compare values between categories. It shows the data of different categories and counts the number of elements in each category.

The bar chart provided by LTS consists of vertical bars and horizontal bars. The width of the rectangle block is fixed, and the height indicates the value. When multiple columns of data are mapped to the Y axis, the data is displayed in group columns.

By default, vertical bars are used. You can select either vertical or horizontal bars. A bar chart contains the following elements:

  • X axis (horizontal axis)
  • Y axis (vertical axis)
  • Rectangular block
  • Legend
