Theming

The theme for each graph can be customized. Children passed to a <Stonk> instance will be passed to the SVG's <defs> element. The following <linearGradient> IDs are used:

id	Description
positive-gradient	The background gradient for positive graphs
negative-gradient	The background gradient for negative graphs
positive-line	The stroke line gradient for positive graphs
negative-line	The stroke line gradient for negative graphs
baseline	The stroke line gradient for the graph's baseline

Props

Name	Type	Default	Description
data	number[]	-	The data for the line plot
className	string	'stonk'	Optional className attribute
granularity	number	10	The number of plots on the graph
height	number	100	The height of the graph (pixels)
isPositive	boolean	-	Overrides the styling for whether the net change of the graph is positive or negative
showBaseline	boolean	-	Override whether or not the zero line is visible. By default, the line isn't shown unless the data prop contains negative values
width	number	200	The width of the graph (pixels)

Note: In the case when granularity is smaller than the data points provided, a select number of plots are shown. In the case that granularity is larger than the data provided, the graph is pushed to the right.
