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

align | vertical_align

layout

x | y

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.

Spline

A spline can be added by including a separate chart data with the type: 'spline' attribute.
A color can also be specified for the spline.

<% data = [{
    name: 'Number of Installations',
    data: [1475,200,3000,654,656]
}, {
    type: 'spline',
    name: 'Trend Line',

    color: '#F9BB00',
}] %>

<%= pb_rails("bar_graph", props: {

Color Overrides

<% data = [{

    data: [1475,200,3000,654,656]
}, {
    name: 'Manufacturing',
    data: [4434,524,2320,440,500]
}, {
    name: 'Sales & Distribution',
    data: [3387,743,1344,434,440,]

    name: 'Other',
    data: [1111,677,3245,500,200]

<%= pb_rails("bar_graph", props: {

    chart_data: data,
    id: "bar-colors",
    y_axis_min: 0,
    x_axis_categories:['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    title: 'Bar Graph with Custom Data Colors',
    colors: ['data-4', 'data-5', 'data-6', 'data-7', 'data-8']
}) %>

Custom Overrides

The custom_options 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.

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

<% bar_graph_options = {
  customOptions: {
    yAxis: {
      tickInterval: 5,
    },
    xAxis: {
      categories: [
        raw(pb_rails("icon", props: { icon: "frown", color: "error", size: "2x" })),
        raw(pb_rails("icon", props: { icon: "frown", color: "warning", size: "2x" })),
        raw(pb_rails("icon", props: { icon: "frown-open", color: "neutral", size: "2x" })),
        raw(pb_rails("icon", props: { icon: "smile", color: "category_7", size: "2x" })),
        raw(pb_rails("icon", props: { icon: "smile-beam", color: "success", size: "2x" }))
      ],
      labels: {
        useHTML: true,
        sytle: {
          fontSize: '1.4em',
        },
        y: 42,
      },
    },
    legend: {
      itemMarginTop: 62,
    },
  } 
} %>

<%= pb_rails("bar_graph", props: {
    chart_data: data,
    id: "bar-default",
    legend: true,
    title: 'Bar Graph with Custom Overrides',
    custom_options: bar_graph_options
}) %>

Stacked

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

<% data = [{
    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],
  }] %>

<%= pb_rails("bar_graph", props: {
    axis_title: 'Number of Employees',
    chart_data: data,
    id: "bar-default",
    y_axis_min: 0,
    x_axis_categories:['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    stacking: "normal",
    title: 'Bar Graph with Stacked Columns',
    legend: true,
}) %>

Negative Numbers

<% data = [{
    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
  }] %>

<%= pb_rails("bar_graph", props: {
    axis_title: 'Number of Employees',
    chart_data: data,
    id: "bar-default",
    x_axis_categories:['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    title: 'Bar Graph with Negative Numbers',
    legend: true,
}) %>

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.

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

<% axis_titles = [{name: "Number of Installations"}, {name: "Percentage"}] %>

<% axis_formats = [{format: ""}, {format: "{value}%"}] %>

<%= pb_rails("bar_graph", props: {
    axis_format: axis_formats,
    axis_title: axis_titles,
    chart_data: data,
    id: "bar-spline",
    y_axis_min: 0,
    x_axis_categories:['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    subtitle: 'Source: thesolarfoundation.com',
    title: 'Bar Graph with Secondary Y-axis',
    legend: true,
}) %>
