Description
Props
3 props
dots
boolean
false
Mark each datum with a dot.
baseline
number
–
Reference value (e.g. previous close) drawn as a dashed line. A single series with no explicit tone auto-tones success/destructive by whether its last value sits above or below the baseline - the trading-app gain/loss idiom.
fade
boolean
false
Soft gradient fade under the lead (first) series' line (the price-chart look).

Usage

<LineChart
title="Active users"
labels={["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul"]}
series={[
{ label: "Web", values: [119, 122, 131, 147, 157, 176, 182] },
{ label: "Mobile", values: [63, 93, 101, 121, 162, 207, 251] }
]}
/>
curved draws a monotone cubic that never overshoots the data, dots marks each datum, and baseline + fade give the trading-app price idiom (dashed previous close, gain/loss auto tone, gradient fill). A series that means success or failure carries its own success / destructive tone instead of a ramp color. Press or scrub the plot to inspect a category.
