Shadcn UI is a utility-first CSS library, made especially for React with the purpose of helping developers quickly create beautiful and easy-to-use UIs. It offers a large selection of components that simplify the process of building the front end of any app, website, or dashboard. Additionally, it is one of the fastest-growing libraries and it is based on the trending Radix UI!

The following are a few advantages of using Shadcn UI:

Efficiency: The Shadcn library gives you the option to pick and choose the elements you are going to use in your app, having a CLI through which you can download only the components you need, therefore having a lighter and more organized app.
Speed: The components not only follow the pre-defined class system of Tailwind CSS that most developers are accustomed to but are also structured so that users can easily combine and modify them to fit their needs.
Consistency: Developers can make sure that the design is the same across all pages and components by using the theme styling offered by the library.
Customizability: Since the Shadcn UI components are unstyled and follow a simple theme, you can easily add your style or adapt the components to your existing app's theme.

Most apps now have data displayed by charts, even if we speak of an admin dashboard or a stock exchange main page. This being said, here is how to make a chart card using Shadcn UI. 👇🏽

Step 1: Setting up the Tailwind CSS config file

Let’s set up our project by creating the Tailwind CSS config file and adding base CSS. Here we will use some colors, shadows, and more from the Horizon UI template for Shadcn UI.

tailwind.config.ts



const config = {
  darkMode: ['class'],
  content: [
    './app/**/*.{js,ts,jsx,tsx,mdx}',
    './components/**/*.{js,ts,jsx,tsx,mdx}',
    // Or if using `src` directory:
    './src/**/*.{js,ts,jsx,tsx,mdx}'
  ],
  prefix: '',
  theme: {
    extend: {
      fontFamily: {
        jakarta: ['Inter', 'sans-serif'],
        poppins: ['Poppins', 'sans-serif']
      },
      height: {
        '300px': '300px',
        '500px': '500px',
        sidebar: 'calc(100vh - 32px)'
      },
      colors: {
        border: 'hsl(var(--border))',
        input: 'hsl(var(--input))',
        ring: 'hsl(var(--ring))',
        background: 'hsl(var(--background))',
        foreground: 'hsl(var(--foreground))',
        primary: {
          DEFAULT: 'hsl(var(--primary))',
          foreground: 'hsl(var(--primary-foreground))'
        },
        secondary: {
          DEFAULT: 'hsl(var(--secondary))',
          foreground: 'hsl(var(--secondary-foreground))'
        },
        destructive: {
          DEFAULT: 'hsl(var(--destructive))',
          foreground: 'hsl(var(--destructive-foreground))'
        },
        muted: {
          DEFAULT: 'hsl(var(--muted))',
          foreground: 'hsl(var(--muted-foreground))'
        },
        accent: {
          DEFAULT: 'hsl(var(--accent))',
          foreground: 'hsl(var(--accent-foreground))'
        },
        popover: {
          DEFAULT: 'hsl(var(--popover))',
          foreground: 'hsl(var(--popover-foreground))'
        },
        card: {
          DEFAULT: 'hsl(var(--card))',
          foreground: 'hsl(var(--card-foreground))',
          border: 'hsl(var(--border))'
        }
      },
      borderRadius: {
        lg: 'var(--radius)',
        md: 'calc(var(--radius) - 2px)',
        sm: 'calc(var(--radius) - 4px)'
      },
      keyframes: {
        'accordion-down': {
          from: { height: '0' },
          to: { height: 'var(--radix-accordion-content-height)' }
        },
        'accordion-up': {
          from: { height: 'var(--radix-accordion-content-height)' },
          to: { height: '0' }
        }
      },
      animation: {
        'accordion-down': 'accordion-down 0.2s ease-out',
        'accordion-up': 'accordion-up 0.2s ease-out'
      }
    }
  }
};

export default config;

Step 2: Import Shadcn chart components via CLI

Simply use the following command in your terminal to add the Shadcn Chart component :



npx shadcn@latest add chart

Step 3: Import the components provided by Shadcn and add them to your component

In this example, we are going to create a bar chart, which has a custom tooltip when the user hovers the cart, as well as a cartesian grid background. Below the chart, we will later add an axis to better display the timespan of the data.

To adapt the chart to:

First, import the following components:



import {
  ChartConfig, // this is the type for typescript users!
  ChartContainer,
  ChartTooltip,
  ChartTooltipContent
} from '@/components/ui/chart';


import { Bar, BarChart, CartesianGrid, XAxis } from 'recharts';

For the chart to be adapted to the theme, we have to write some simple, but effective config:



const chartConfig = {
  desktop: {
    label: 'Desktop',
    color: 'var(--chart-1)'
  },
  mobile: {
    label: 'Mobile',
    color: 'var(--chart-2)'
  }
} satisfies ChartConfig; // this is the type for typescript users!

This is the structure of the default chart, without any addons. It follows the data in the example:



const chartData = [
  { month: 'January', desktop: 186, mobile: 80 },
  { month: 'February', desktop: 305, mobile: 200 },
  { month: 'March', desktop: 237, mobile: 120 },
  { month: 'April', desktop: 73, mobile: 190 },
  { month: 'May', desktop: 209, mobile: 130 },
  { month: 'June', desktop: 214, mobile: 140 }
];

export default function BarChartComponent() {
  return (
    <ChartContainer
      className="aspect-auto h-[300px] xl:h-[200px] 2xl:h-[250px] w-full"
      config={chartConfig}
    >
      <BarChart accessibilityLayer data={chartData}>
        <Bar dataKey="desktop" fill="var(--color-desktop)" radius={4} />
        <Bar dataKey="mobile" fill="var(--color-mobile)" radius={4} />
      </BarChart>
    </ChartContainer>
  );
}

Up until now, it should look something like this:

To add the addons, just add the following components (XAxis, CartesianGrid, and ChartTooltip):



const chartData = [
  { month: 'January', desktop: 186, mobile: 80 },
  { month: 'February', desktop: 305, mobile: 200 },
  { month: 'March', desktop: 237, mobile: 120 },
  { month: 'April', desktop: 73, mobile: 190 },
  { month: 'May', desktop: 209, mobile: 130 },
  { month: 'June', desktop: 214, mobile: 140 }
];

export default function BarChartComponent() {
  return (
    <ChartContainer
      className="aspect-auto h-[300px] xl:h-[200px] 2xl:h-[250px] w-full"
      config={chartConfig}
    >
      <BarChart accessibilityLayer data={chartData}>
          <CartesianGrid vertical={false} />
          <XAxis
            dataKey="month"
            tickLine={false}
            tickMargin={10}
            axisLine={false}
            tickFormatter={(value) => value.slice(0, 3)}
          />
          <ChartTooltip
            cursor={false}
            content={<ChartTooltipContent indicator="dashed" />}
          />
        <Bar dataKey="desktop" fill="var(--color-desktop)" radius={4} />
        <Bar dataKey="mobile" fill="var(--color-mobile)" radius={4} />
      </BarChart>
    </ChartContainer>
  );
}

Step 4: You’re done! 🎉

Now the component is ready to use in your project. You can add the custom data, or change the styles in the global.css file to your liking. This is the final result :

In conclusion, Shadcn UI can be used for a variety of tasks when it comes to UI, including ones like charts, cards, and more, which can be uniformly modified by changing the main theme.

More cards like the one we made, components like navbars, dropdowns, and so on, are available in Horizon AI Boilerplate!
