Render recharts svg chart inside a PDF document created with react-pdf/renderer

Chart.jsx

import React from 'react';
import { Global } from 'recharts';

import { htmlSvgToPdfSvg } from '../imageFromSvg';

export const ChartSvg = ({ debug, style, children, width, height }) => {
  return chartToPdfSvg(children, width, height, debug, style);
};

const chartToPdfSvg = (children, width, height, debug, style) => {
  Global.set('isSsr', true);
  const component = htmlSvgToPdfSvg(children);
  Global.set('isSsr', false);

  const result = React.cloneElement(component, { width, height, debug, style });
  return result;
};

export default ChartSvg;

ExampleUsage.jsx

import { View } from '@react-pdf/renderer';
import { CartesianGrid, Label, Scatter, ScatterChart, XAxis, YAxis } from 'recharts';

import Chart from './Chart';

export const ExampleUsage = ({ data = getSampleData() }) => (
  <View>
    <Chart width={600} height={300}>
      <MyRechartsChart data={data} />
    </Chart>
  </View>
);

const MyRechartsChart = ({ width, height, data }) => (
  <ScatterChart width={width} height={height}>
    <CartesianGrid />
    <XAxis name="x" dataKey="x" />
    <YAxis name="y" dataKey="y" />
    <Scatter name="My Scatter" data={data} isAnimationActive={false} />
  </ScatterChart>
)

function getSampleData() {
  return [
    { x: 100, y: 100 },
    { x: 200, y: 100 },
    { x: 200, y: 150 },
    { x: 150, y: 200 },
    { x: 125, y: 150 }
  ]
}

export default ExampleUsage;

imageFromSvg.js

import React, { createElement } from 'react';
import ReactDom from 'react-dom/server';
import reactHtmlParser from 'react-html-parser';

export const htmlSvgToPdfSvg = (children) => {
  const svgString = ReactDom
    .renderToStaticMarkup(children)
    .replaceAll('px', 'pt');

  const [component] = reactHtmlParser(svgString, { transform: convertToPdfSvg });
  return component;
};

function convertToPdfSvg(node, index) {
  if (node.type == 'text') {
    return node.data;
  }

  node.props = { key: index };

  Object.entries(node.attribs).forEach(([key, value]) => {
    const [first, ...rest] = key.split('-');

    const newKey = [first, ...rest.map(word => `${word[0].toUpperCase()}${word.slice(1)}`)].join('');
    node.props[newKey] = value;
  });

  node.name = node.name?.toUpperCase();
  if (node.name == 'CLIPPATH') node.name = 'CLIP_PATH';

  // we're removing nested <defs> because they don't work
  if (node.name == 'DEFS' && node.parent.name != 'SVG') return null;

  if (node.children) node.children = node.children.map(convertToPdfSvg);
  return createElement(node.name, node.props, node.children);
}

export default htmlSvgToPdfSvg;

package.json

{
  "dependencies": {
    "@react-pdf/renderer": "^2.0.16",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-html-parser": "^2.0.2",
    "recharts": "^2.0.9"
  }
}

export const htmlSvgToPdfSvg = (children) => {
  const svgString = ReactDom
    .renderToStaticMarkup(children)
    .replaceAll('px', 'pt');

  const [component] = reactHtmlParser(svgString, { transform: convertToPdfSvg });
  return component;
};

Instead of rendering to string and then using reactHtmlParser we can probably iterate children and achieve a similar result

Hi kidroca! Thanks for sharing to the community 🙌🏼
I'm following this steps, but I'm not able to render properly any recharts component, except the Line Chart one.
Here is the link to the code in a Github repository https://github.com/griselmatosm/recharts-react-pdf-test

Thanks a lot in advance!

Hi @griselmatosm,

The exact same code from this gist is still used in our project and there are no problems
The only difference is we pass a isAnimationActive={false} prop to the chart when we want to render it in PDF
The isAnimationActive={false} is then set on the <Scatter> component:

          <Scatter
            isAnimationActive={isAnimationActive}
            name={referenceDataLabel}
            data={referenceRecords}
            r={5}
            strokeWidth={2}
          />

So maybe that's all that you need to do

Thanks so much! That's it!

Hello, tell me please. I get this error: TypeError: renderFn is not a function .

Trying to figure this out myself. I also see: TypeError: renderFn is not a function

Hello @dylnclrk, my reason was npm conflict. Try create new app, for testing. And I created GitHub tutorial, how I made this.

i am using same configs in my tupescript project, but getting renderFn is not a function, and I don't think there are any conflicts.

I'm having the same issue with renderFn. Anyone figure this out?

I have digged into the node modules and found out that recharts inner tags "TITLE" and "DEFS" are breaking render function. I've included this line of code to ditch those two values and it's sucessfuly rendered.

if (node.name == "TITLE" || node.name == "DESC") return null;

Result:

Hope it helps!

I just created https://github.com/EvHaus/react-pdf-charts which allows for recharts to be rendered into react-pdf. It had only very basic support at the moment, but I'm hoping with some help from the community -- we can get to full support.

@EvHaus it does not work properly. I can see that Path is being converted to Line and it's not even found in parsed HTML string.

probably Html parser is bringing this issue

this is what I get after using an example

@leq382121 Hmm. Could you open an issue in https://github.com/EvHaus/react-pdf-charts/issues with the code you're using and I'll take a look.

@EvHaus @leq382121 I am facing an issue while displaying the BarChart inside my pdf.... So when I am using " import ReactPDFChart from "react-pdf-charts" " this and trying to get my BarChart then Barchart is only showing the CartesianGrid, XAxis and YAxis but no values.
Below is the code with "ReactPDFChart" -

import React from "react";
import ReactPDFChart from "react-pdf-charts";
import { BarChart, Bar, XAxis, YAxis, CartesianGrid } from "recharts";

const data = [
{ name: 'A', uv: 4000, pv: 2400, amt: 2400 },
{ name: 'B', uv: 3000, pv: 1398, amt: 2210 },
{ name: 'C', uv: 2000, pv: 9800, amt: 2290 },
{ name: 'D', uv: 2780, pv: 3908, amt: 2000 },
{ name: 'E', uv: 1890, pv: 4800, amt: 2181 },
{ name: 'F', uv: 2390, pv: 3800, amt: 2500 },
{ name: 'G', uv: 3490, pv: 4300, amt: 2100 },
];

// Silence useLayoutEffect does nothing on the server warnings. These come
// from recharts but they're harmless and just clutter the console output.
const consoleError = console.error;
console.error = function (message) {
if (message?.startsWith('Warning: useLayoutEffect does nothing on the server')) return;
consoleError.apply(console, arguments);
};

const PdfBarChart = () => (
<ReactPDFChart> <BarChart data={data} width={500} height={300}> <XAxis dataKey="name" /> <YAxis /> <CartesianGrid stroke="#ccc" strokeDasharray="3 3" /> <Bar dataKey="uv" fill="#8884d8" /> <Bar dataKey="pv" fill="#82ca9d" /> </BarChart> </ReactPDFChart>
);

export default PdfBarChart;

And when I try the same above code without "ReactPDFChart" it is giving me error like below -

htmlLayer.getElementsByClassName is not a function
TypeError: htmlLayer.getElementsByClassName is not a function
at CartesianAxis.componentDidMount (http://localhost:3000/static/js/bundle.js:144491:28)

So can anyone please guide or help me to figure this out and render the Bar and another Charts in the pdf.

@Kartik0899 Could you please open a new issue at https://github.com/EvHaus/react-pdf-charts/issues and we can take it from there.

BarChart doesn't work properly, ni the PieChart

BarChart doesn't work properly, ni the PieChart

@omarhsounalogient

You need to add isAnimationActive={false} when rendering BarChart and PieChart component in the browser.
For example -
<Bar isAnimationActive={false} dataKey="uv" fill="#8884d8" />
<Pie isAnimationActive={false} dataKey="value" nameKey="name" cx="25%" cy="50%" outerRadius={50} fill="#000" label />

Hope it helps!

I'm having the same issue with renderFn. Anyone figure this out?

I degraded the version react-pdf ,and it worked
