Bar Graph

Bar graphs are used to compare data. Bar graphs are not typically used to show percentages. The default height of bar graph is 400px and can be changed. The default height is in pixel units, but can also use percentage string (percentage would be that of the width. For example, height:"50%" would mean that the height is 50% of the width). This allows for preserving the aspect ratio across responsive sizes. 

For more information, see: highcharts/chart.height.

Legend Position

Prop

layout determines the position of the legend items
layout: proximate will place the legend items as close as possible to the graphs they're representing. It will also determine whether to place the legend above/below or on the side of the plot area, if the legend is in a corner.
x offsets the legend relative to its horizontal alignmnet. Negative x moves it to the left, positive x moves it to the right
y offsets the legend relative to its vertical alignmnet. Negative y moves it up, positive y moves it down.

Custom Overrides

The customOptions prop provides comprehensive access to additional Highcharts options that are not explicitly defined as props.
It's important to note that certain options may require specific script imports to function properly.

Note: If you are having trouble getting any Highcharts options to work, please match the formatting of our staticOptions. For example, yAxis will need to be wrapped with square brackets.

You may also need to override any of the defaults in order to get that options to work.

import React from 'react'
import ReactDOMServer from 'react-dom/server'
import BarGraph from 'playbook-ui'
import Icon from 'playbook-ui'

const chartData = [
  {
    name: 'Role',
    data: [0, 200, 300, 654, 656],
  },
  {
    name: 'Company',
    data: [150, 524, 320, 440, 500],
  },
]

const renderIcon = (iconName, color) => {
  return ReactDOMServer.renderToStaticMarkup(
  <Icon
      color={color}
      icon={iconName}
  />)
};

      },

        fontSize: '1.4em',
      },
      y: 42,
    },
  },

Stacked

The stacking prop can be used for a stacked bar graph. The prop allows for normal or percent as options.

import React from 'react'

import BarGraph from 'playbook-ui'

const chartData = [{
  name: 'Installation',
  data: [1475, 200, 3000, 654, 656],
}, 
{
  name: 'Manufacturing',
  data: [1270, 800, 200, 454, 956],
}, {
  name: 'Sales & Distribution',
  data: [975, 1600, 1500, 924, 500],
}]


const BarGraphStacked = (props) => (
  <div>
    <BarGraph
        axisTitle="Number Of Employees"
        chartData={chartData}
        id="bar-default"
        legend
        stacking="normal"
        title="Bar Graph with Stacked Columns"
        xAxisCategories={['Jan', 'Feb', 'Mar', 'Apr', 'May']}
        yAxisMin={0}
    />
  </div>
)

export default BarGraphStacked

Negative Numbers

import React from 'react'

import BarGraph from 'playbook-ui'

const chartData = [{
  name: 'Installation',
  data: [-475, 400, -1000, 354, -856],
  threshold: 0
}, {
  name: 'Manufacturing',
  data: [1475, 200, 1000, 654, -656],
  threshold: 0
},

  name: 'Sales & Distribution',
  data: [1270, 100, -1200, 554, 756],
  threshold: 0
}]


const BarGraphStacked = (props) => (
  <div>
    <BarGraph
        axisTitle="Number of Employees"
        chartData={chartData}
        id="bar-default"
        legend
        title="Bar Graph with Negative Numbers"
        xAxisCategories={['Jan', 'Feb', 'Mar', 'Apr', 'May']}
    />
  </div>
)

export default BarGraphStacked

Secondary Y-Axis

Optionally add a second yAxis to support secondary datasets (e.x., a spline) by passingyAxis: 1 to the second node of your chartData array.

To customize the format and/or title of your secondary yAxis, pass your desired values as arrays through the axisFormat and axisTitle props, respectively.

import React from 'react'

import BarGraph from 'playbook-ui'

const chartData = [{
  name: 'Number of Installations',
  data: [1475, 200, 3000, 654, 656],
}, {
  type: 'spline',
  name: 'Percentage',
  data: [48, 70, 25, 55, 72],
  color: '#F9BB00',
  yAxis: 1
}]

const axisTitles = [ {name: "Number of Installations"}, {name: "Percentage"}]

const axisFormats = [{format: ""}, {format: "{value}%"}]

const BarGraphSecondaryYAxis= (props) => (
  <div>
    <BarGraph
        axisFormat={axisFormats}
        axisTitle={axisTitles}
        chartData={chartData}
        id="bar-spline"
        legend
        title="Bar Graph with Secondary Y-axis"
