Components

Area Chart

An area chart displays quantitative data graphically. It is based on the line chart but the area between x-axis and line is emphasized with color.

   

Import AreaChart

Tremor exports one component to create an area chart.

import { AreaChart } from "@tremor/react";

Usage example

The example below shows a a chart composition combining a Card with Title and AreaChart components. Note: For the height, a number value has to be set (e.g, h-72, or h-[500px]. Keep in mind that h-full won't work.)

import { Card, Title, AreaChart } from "@tremor/react";

const chartdata = [
  {
    date: "Jan 22",
    SemiAnalysis: 2890,
    "The Pragmatic Engineer": 2338,

];

const dataFormatter = (number: number) => {
  return "$ " + Intl.NumberFormat("us").format(number).toString();
};
