Sparkline

[ZettaDevs]

I've followed the tutorial as closely as possible, however, the Sparkline still won't show. I've logged the data, its clearly being passed into the Sparkline component, but the chart just won't show. Any ideas?

My SparkLine.js file currently looks like this (Without console logs)

import React from 'react';
import {SparklineComponent , Inject, SparklineTooltip } from '@syncfusion/ej2-react-charts';

const SparkLine = ({id, height, width, color, data, type, currentColor}) => {
  return (
    <SparklineComponent 
    id={id}
    height={height}
    width={width}
    lineWidth={1}
    valueType="Numeric"
    fill={color}
    border={{ color: currentColor, width: 2 }}
    dataSource={data}
    xName="x"
    yName="y"
    type={type}
    >
      <Inject services={[SparklineTooltip]} />
    </SparklineComponent>
  )
}

export default SparkLine

and my Ecommerce.jsx currently looks like this:

`import React from 'react'
import { BsCurrencyDollar } from 'react-icons/bs';
import {GoDotFill} from 'react-icons/go';

import {Stacked, Pie, Button, SparkLine} from '../components';
import {earningData, SparklineAreaData, ecomPieChartData} from '../data/dummy';
import { useStateContext } from '../contexts/ContextProvider';

const Ecommerce = () => {
return (

Hi there, I encountered the same issue. Turns out in the dummy dataset the SparklineAreaData has column labels 'x' and 'yval' instead of 'y'. In the SparkLine.jsx replace it with

  xName="x"
  yName="yval"

Or change the dummy data naming
