Gantt
Gantt compares ranges of continuous data. Each range is represented by an array of two numeric values. The first column of each data row must contain a string or number to represent that row's category. Each additional column must contain an array of two numbers.
Gantt also supports multiple ranges per data row.
The orientation is set to 'horizontal' by default so yAxisTitle is used to assign the horizontal axis' label.
xAxisSeriesPaddingInner can be used to set the ratio between white space and bar size (per series).
It also supports duplicate category values.
For documentation on axis-specific properties, like those used in the below example, take a look at the Axis Documentation.
