Barpolar

Overview

The barpolar trace type is used to create bar charts in polar coordinates. This is particularly useful for displaying data that is cyclical or directional in nature, such as wind directions, time-of-day activities, or any phenomena that repeats over a circular dimension.

You have extensive control over the appearance of the bars through the marker and insidetextfont attributes. You can set colors, opacity, line styles, and more. The bars can be customized to start at a specific radial axis and extend to another, allowing for flexible representations.

Common Uses

  • Wind Rose Charts: Visualizing wind speed and direction distributions.
  • Circular Histograms: Displaying the frequency of events over a circular variable like time of day or compass direction.
  • Directional Data Representation: Showcasing data that has a directional component (e.g., animal migration patterns).
  • Cyclical Phenomena Visualization: Illustrating patterns that repeat over a cycle (e.g., seasonal sales data).

  1. Sets where the bar base is drawn (in radial axis units). In stack barmode, traces that set base will be excluded and drawn in overlay mode instead.
  2. Sets the source reference on Chart Studio Cloud for base.
  3. Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, scatter traces also appends customdata items in the markers DOM elements
  4. Sets the source reference on Chart Studio Cloud for customdata.
  5. Sets the r coordinate step.
  6. Sets the theta coordinate step. By default, the dtheta step equals the subplot's period divided by the length of the r coordinates.
  7. 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.
  8. Sets the source reference on Chart Studio Cloud for hoverinfo.
  9. 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
  10. Sets the source reference on Chart Studio Cloud for align.
  11. Sets the background color of the hover labels for this trace
  12. Sets the source reference on Chart Studio Cloud for bgcolor.
  13. Sets the border color of the hover labels for this trace.
  14. Sets the source reference on Chart Studio Cloud for bordercolor.
  15. Sets the source reference on Chart Studio Cloud for color.
  16. 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.
  17. Sets the source reference on Chart Studio Cloud for family.
  18. 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.
  19. Sets the source reference on Chart Studio Cloud for lineposition.
  20. 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.
  21. Sets the source reference on Chart Studio Cloud for shadow.
  22. Sets the source reference on Chart Studio Cloud for size.
  23. Sets whether a font should be styled with a normal or italic face from its family.
  24. Sets the source reference on Chart Studio Cloud for style.
  25. Sets capitalization of text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.
  26. Sets the source reference on Chart Studio Cloud for textcase.
  27. Sets the variant of the font.
  28. Sets the source reference on Chart Studio Cloud for variant.
  29. Sets the weight (or boldness) of the font.
  30. Sets the source reference on Chart Studio Cloud for weight.
  31. 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.
  32. Sets the source reference on Chart Studio Cloud for namelength.
  33. 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. 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>.
  34. Sets the source reference on Chart Studio Cloud for hovertemplate.
  35. Same as text.
  36. Sets the source reference on Chart Studio Cloud for hovertext.
  37. 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.
  38. Sets the source reference on Chart Studio Cloud for ids.
  39. Sets the reference to a legend to show this trace in. References to these legends are legend, legend2, legend3, etc. Settings for these legends are set in the layout, under layout.legend, layout.legend2, etc.
  40. Sets the legend group for this trace. Traces and shapes part of the same legend group hide/show at the same time when toggling legend items.
  41. 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.
  42. 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.
  43. 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.
  44. Sets whether a font should be styled with a normal or italic face from its family.
  45. Sets capitalization of text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.
  46. Sets the variant of the font.
  47. Sets the weight (or boldness) of the font.
  48. Sets the title of the legend group.
  49. Sets the legend rank for this trace. Items and groups with smaller ranks are presented on top/left side while with reversed legend.traceorder they are on bottom/right side. The default legendrank is 1000, so that you can use ranks less than 1000 to place certain items before all unranked items, and ranks greater than 1000 to go after all unranked items. When having unranked or equal rank items shapes would be displayed after traces i.e. according to their order in data and layout.
  50. Sets the width (in px or fraction) of the legend for this trace.
  51. Determines whether the colorscale is a default palette (autocolorscale: true) or the palette determined by marker.colorscale. Has an effect only if in marker.color is set to a numerical array. In case colorscale is unspecified or autocolorscale is true, the default palette will be chosen according to whether numbers in the color array are all positive, all negative or mixed.
  52. Determines whether or not the color domain is computed with respect to the input data (here in marker.color) or the bounds set in marker.cmin and marker.cmax Has an effect only if in marker.color is set to a numerical array. Defaults to false when marker.cmin and marker.cmax are set by the user.
  53. Sets the upper bound of the color domain. Has an effect only if in marker.color is set to a numerical array. Value should have the same units as in marker.color and if set, marker.cmin must be set as well.
  54. Sets the mid-point of the color domain by scaling marker.cmin and/or marker.cmax to be equidistant to this point. Has an effect only if in marker.color is set to a numerical array. Value should have the same units as in marker.color. Has no effect when marker.cauto is false.
  55. Sets the lower bound of the color domain. Has an effect only if in marker.color is set to a numerical array. Value should have the same units as in marker.color and if set, marker.cmax must be set as well.
  56. Sets the marker color. It accepts either a specific color or an array of numbers that are mapped to the colorscale relative to the max and min values of the array or relative to marker.cmin and marker.cmax if set.
  57. Sets a reference to a shared color axis. References to these shared color axes are coloraxis, coloraxis2, coloraxis3, etc. Settings for these shared color axes are set in the layout, under layout.coloraxis, layout.coloraxis2, etc. Note that multiple color scales can be linked to the same color axis.
  58. Sets the color of padded area.
  59. Sets the axis line color.
  60. Sets the width (in px) or the border enclosing this color bar.
  61. Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If none, it appears as 1,000,000,000. If e, 1e+9. If E, 1E+9. If power, 1x10^9 (with 9 in a super script). If SI, 1G. If B, 1B.
  62. Sets the length of the color bar This measure excludes the padding of both ends. That is, the color bar length is this length minus the padding on both ends.
  63. Determines whether this color bar's length (i.e. the measure in the color variation direction) is set in units of plot fraction or in *pixels. Use len to set the value.
  64. Hide SI prefix for 10^n if |n| is below this number. This only has an effect when tickformat is SI or B.
  65. Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to nticks. Has an effect only if tickmode is set to auto.
  66. Sets the orientation of the colorbar.
  67. Sets the axis line color.
  68. Sets the width (in px) of the axis line.
  69. If "true", even 4-digit integers are separated
  70. If all, all exponents are shown besides their significands. If first, only the exponent of the first tick is shown. If last, only the exponent of the last tick is shown. If none, no exponents appear.
  71. Determines whether or not the tick labels are drawn.
  72. If all, all tick labels are displayed with a prefix. If first, only the first tick is displayed with a prefix. If last, only the last tick is displayed with a suffix. If none, tick prefixes are hidden.
  73. Same as showtickprefix but for tick suffixes.
  74. Sets the thickness of the color bar This measure excludes the size of the padding, ticks and labels.
  75. Determines whether this color bar's thickness (i.e. the measure in the constant color direction) is set in units of plot fraction or in pixels. Use thickness to set the value.
  76. Sets the angle of the tick labels with respect to the horizontal. For example, a tickangle of -90 draws the tick labels vertically.
  77. Sets the tick color.
  78. 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.
  79. 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.

And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: %h for half of the year as a decimal number as well as %{n}f for fractional seconds with n digits. For example, 2016-10-13 09:15:23.456 with tickformat %H~%M~%S.%2f would display 09~15~23.46
  86. Determines how we handle tick labels that would overflow either the graph div or the domain of the axis. The default value for inside tick labels is hide past domain. In other cases the default is hide past div.
  87. Determines where tick labels are drawn relative to the ticks. Left and right options are used when orientation is h, top and bottom when orientation is v.
  88. Sets the spacing between tick labels as compared to the spacing between ticks. A value of 1 (default) means each tick gets a label. A value of 2 means shows every 2nd label. A larger value n means only every nth tick is labeled. tick0 determines which labels are shown. Not implemented for axes with type log or multicategory, or when tickmode is array.
  89. Sets the tick length (in px).

  124. Sets a reference to a shared color axis. References to these shared color axes are coloraxis, coloraxis2, coloraxis3, etc. Settings for these shared color axes are set in the layout, under layout.coloraxis, layout.coloraxis2, etc. Note that multiple color scales can be linked to the same color axis.
