You can configure the appearance of the timeline: set the background fill, the stroke of columns, etc. It is possible to apply the same color to all rows or different colors to odd and even rows.

Combine getTimeline() with the following methods:

Note 1: See also Data Grid: Appearance to learn how to configure the appearance of the data grid.

Note 2: The Basic Settings: Background and Basic Settings: Rows and Columns sections explain how to apply some appearance settings simultaneously to the data grid and timeline. Please note that this is the only way to set the row stroke.

The sample below shows how to adjust the appearance of the timeline:

// configure the visual settings of the timeline
var timeline = chart.getTimeline();
timeline.rowEvenFill("gray 0.3");
timeline.rowOddFill("gray 0.1");
timeline.rowHoverFill("#ffd54f 0.3");
timeline.rowSelectedFill("#ffd54f 0.3");
