Bar

Overview

The bar trace type is used to display data as bars.

You have pretty broad control over the appearance of the bars via the marker attributes. You can set the fill color, opacity, pattern, line color, width, etc. You can also configure display the bars as either grouped or stacked.

Common Uses

  • Categorical Data Comparison: Visualizing data across distinct categories (e.g., sales by product type).
  • Grouped Bar Charts: Comparing multiple series side by side (e.g., monthly sales by region).
  • Stacked Bar Charts: Showing cumulative data (e.g., revenue breakdown by product within a year).
  • Horizontal Bar Charts: Comparing data where horizontal labels are more readable (e.g., ranking of countries by population).
  • Time-Series Data (Categorical): Displaying data changes over time with categories as the x-axis (e.g., yearly revenue growth by product).

Common Configurations

Here's a really simple bar chart: You can copy this code below to create this chart in your project: 

models:
  - name: monty-python-quest-data
    args:
      - curl
      - "https://raw.githubusercontent.com/visivo-io/data/refs/heads/main/monty_python_quests.csv"
traces:
  - name: Count Enemies Encountered by Knight
    model: ${ref(monty-python-quest-data)}
    cohort_on: "person"
    props:
      type: bar 
      x: ?{enemy_encountered}
      y: ?{ count(*) }
      text: ?{ count(*) }
    order_by: 
      - ?{ count(*) desc}
charts: 
  - name: Count Times Enemy Was Encountered by Knight
    traces: 
      - ${ref(Count Enemies Encountered by Knight)}
    layout: 
      title: 
        text: Cohorted Bar<br><sub>The Number of Times an Enemy was Enountered on a Quest by Knight</sub>

You can use the trace.cohort_on key to create facets in your bar chart. Here's the code: 

models:
  - name: monty-python-quest-data
    args:
      - curl
      - "https://raw.githubusercontent.com/visivo-io/data/refs/heads/main/monty_python_quests.csv"
traces:
  - name: Count Enemies Encountered by Knight
    model: ${ref(monty-python-quest-data)}
    cohort_on: "person"
    props:
      type: bar 
      x: ?{enemy_encountered}
      y: ?{ count(*) }
      text: ?{ count(*) }
    order_by: 
      - ?{ count(*) desc}

charts: 
  - name: Count Times Enemy Was Encountered by Knight
    traces: 
      - ${ref(Count Enemies Encountered by Knight)}
    layout: 
      title: 
        text: Cohorted Bar<br><sub>The Number of Times an Enemy was Enountered on a Quest by Knight</sub>

It can be useful to view some data horizontally.

Here's the code: 

models:
  - name: monty-python-quest-data-h
    args:
      - curl
      - "https://raw.githubusercontent.com/visivo-io/data/refs/heads/main/monty_python_quests.csv"
traces:
  - name: Count Enemies Encountered by Knight H
    model: ${ref(monty-python-quest-data-h)}
    cohort_on: "person"
    props:
      type: bar 
      y: ?{enemy_encountered}
      x: ?{ count(*) }
      text: ?{ count(*) }
      textposition: outside
      textfont:
        size: 15
      orientation: h
    order_by: 
      - ?{ count(*) desc}

charts: 
  - name: Count Times Enemy Was Encountered by Knight H
    traces: 
      - ${ref(Count Enemies Encountered by Knight H)}
    layout: 
      title: 
        text: Horizontal Cohorted Bar<br><sub>The Number of Times an Enemy was Enountered on a Quest by Knight</sub>
      margin: 
        l: 160

  29. Determines the rule used to generate the error bars. If *constant, the bar lengths are of a constant value. Set this constant invalue. If *percent*, the bar lengths correspond to a percentage of underlying data. Set this percentage invalue. If *sqrt*, the bar lengths correspond to the square of the underlying data. If *data*, the bar lengths are set with data setarray`.
  30. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars.
  31. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars in the bottom (left) direction for vertical (horizontal) bars
  32. Determines whether or not this set of error bars is visible.
  33. Sets the width (in px) of the cross-bar at both ends of the error bars.
  34. Determines which trace information appear on hover. If none or skip are set, no information is displayed upon hovering. But, if none is set, click and hover events are still fired.
  35. Sets the source reference on Chart Studio Cloud for hoverinfo.
  36. Sets the horizontal alignment of the text content within hover label box. Has an effect only if the hover label text spans more two or more lines

  40. Sets the border color of the hover labels for this trace.
  41. Sets the source reference on Chart Studio Cloud for bordercolor.
  42. Sets the source reference on Chart Studio Cloud for color.
  43. HTML font family - the typeface that will be applied by the web browser. The web browser can only apply a font if it is available on the system where it runs. Provide multiple font families, separated by commas, to indicate the order in which to apply fonts if they aren't available.
  44. Sets the source reference on Chart Studio Cloud for family.
  45. Sets the kind of decoration line(s) with text, such as an under, over or through as well as combinations e.g. under+over, etc.
  46. Sets the source reference on Chart Studio Cloud for lineposition.
  47. Sets the shape and color of the shadow behind text. auto places minimal shadow and applies contrast text font color. See https://developer.mozilla.org/en-US/docs/Web/CSS/text-shadow for additional options.
  48. Sets the source reference on Chart Studio Cloud for shadow.
  49. Sets the source reference on Chart Studio Cloud for size.
  50. Sets whether a font should be styled with a normal or italic face from its family.
  51. Sets the source reference on Chart Studio Cloud for style.
  52. Sets capitalization of text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.
  53. Sets the source reference on Chart Studio Cloud for textcase.
  54. Sets the variant of the font.
  55. Sets the source reference on Chart Studio Cloud for variant.

  58. Sets the default length (in number of characters) of the trace name in the hover labels for all traces. -1 shows the whole name regardless of length. 0-3 shows the first 0-3 characters, and an integer >3 will show the whole name if it is less than that many characters, but if it is longer, will truncate to namelength - 3 characters and add an ellipsis.
  59. Sets the source reference on Chart Studio Cloud for namelength.
  60. Template string used for rendering the information that appear on hover box. Note that this will override hoverinfo. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%xother}, {%_xother}, {%xother_}. When showing info for several points, xother will be added to those with different x positions from the first point. An underscore before or after (x|y)other will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available in hovertemplate are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are arrayOk: true) are available. Finally, the template string has access to variables value and label. Anything contained in tag <extra> is displayed in the secondary box, for example "{fullData.name}". To hide the secondary box completely, use an empty tag <extra></extra>.
  61. Sets the source reference on Chart Studio Cloud for hovertemplate.
  62. Sets hover text elements associated with each (x,y) pair. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (x,y) coordinates. To be seen, trace hoverinfo must contain a text flag.
  63. Sets the source reference on Chart Studio Cloud for hovertext.
  64. Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.
  65. Sets the source reference on Chart Studio Cloud for ids.
  66. Determines if texts are kept at center or start/end points in textposition inside mode.
  67. Sets the source reference on Chart Studio Cloud for color.
