Below are general recommendations on how to create a timeline chart.
-
Choose a series type
Each event is represented by its name and start/end dates. In this case, the series type should have points with one argument and two values, for example, the Range Bar. -
Bind the series to data
You can bind the series to data directly or use a series template (depending on the data source). These approaches and their differences are described in the Bind Series to Data article. In this demo, we use a series template. -
Line up bars
Specify the barOverlapGroup to arrange bars in a line that displays a combined timeline. -
Rotate the chart
A range bar chart's bars are vertical. To make them horizontal, set the rotated property to true. -
Sort the events chronologically
Arguments maintain objects' order in the data source. If this order is not chronological, use the axis' categories array to specify the order.
