Band Position

Edit this page

Band properties can be used to adjust mark bandwidth or position for band scales, bin intervals, or time unit intervals.

Property Type Description
bandPosition Number

Relative position on a band of a stacked, binned, time unit, or band scale. For example, the marks will be positioned at the beginning of the band if set to 0, and at the middle of the band if set to 0.5.


Line Position

By default, points in line marks are placed at the beginning of a time interval (e.g., “month”):

Setting bandPosition to 0.5 moves the points to the middle of the time interval.

Bar Position

By default, bar marks are placed from the beginning of a time interval (e.g., “month”) to the end of the interval:

Setting bandPosition to 0 moves the bar to center-align with ticks.
