[1.0.0] - 2019-06-20

Added

  • Markdown components support code highlighting - no need to switch to SyntaxHighlighter, which has been removed. Use triple backticks, with the opening backticks followed by the language name or abbreviation. #562 Supported languages:
    • Bash
    • CSS
    • HTTP
    • JavaScript

    • HTML, XML
    • R
    • Ruby
    • SQL

    • Feature release 1.48.0 which contains:

    • Patch releases 1.48.3, 1.48.2, 1.48.1, 1.47.4, 1.47.3, 1.47.2, 1.47.1 containing numerous bug fixes

[0.48.0] - 2019-05-15

Added

  • figure prop in dcc.Graph now accepts a frames key
  • Improved the Dropdown options description for dash-docs #547
  • Added optionHeight prop to Dropdown #552
  • Merged in R dashCoreComponents package and updated to 0.48.0

Removed

  • Removed unused key prop from dcc.ConfirmDialog

[0.47.0] - 2019-04-25

Fixed

  • Fixed style regression in DatePickerSingle and DatePickerRange #518
  • Breaking - In dcc.Input, fixed several HTML properties that weren't properly camel cased and therefore were not actually applied in the DOM #523:
    • autocomplete is now autoComplete
    • autofocus is now autoFocus
    • inputmode is now inputMode
    • maxlength is now maxLength
    • minlength is now minLength
  • Improved property definitions of various components in anticipation of upcoming component validation (plotly/dash-renderer#100). #523
  • Breaking - n_blur_timestamp & n_submit_timestamp in Input & Textarea is now a number instead of a date object/string. This matches the form of n_clicks_timestamp as used in dash_html_components. #523
  • Fixed an issue with ConfirmDialog that could display multiple confirm popups instead of a single popup in certain contexts. #523
  • dcc.Markdown containerProps is now applied to the component's container again. This was broken in 0.45.0's react-markdown upgrade.

Changed

  • dcc.Interval will reset its timer when re-enabled. Previously, if the dcc.Interval was disabled, it's "clock would keep running": when it was reenabled, it would fire at the next interval on the previous clock's schedule, rather than interval milliseconds later. For example, previously the schedule might look like this:

    0 seconds: interval started with `interval=5000`
5 seconds: `n_intervals=1`
7 seconds: callback sets `disabled=True`
10 seconds: interval continues to run, but doesn't fire an update
13 seconds: callback sets `disabled=False`
15 seconds: interval fires an update: `n_intervals=2`

    Now, it will look like this:

    0 seconds: interval started with `interval=5000`
5 seconds: `n_intervals=1`
7 seconds: callback sets `disabled=True` - interval stops
13 seconds: callback sets `disabled=False` - clock resets
18 seconds: interval fires an update: `n_intervals=2`

[0.46.0] - 2019-04-10

[0.17.1] - 2017-01-18

Fixed

  • Previously, if None is supplied to SyntaxHighlighter or Markdown, the component would not render and the app would break. This is problematic because if children isn't supplied (as done in the case for when you are updating that property from a callback), None is the default property. Fixes plotly#147. This bug was introduced in v0.15.4.

[0.17.0] - 2017-01-11

Added

  • The dcc.Graph component now includes pointNumbers inside selectedData and hoverData if the chart type is a histogram, histogram2d, or histogram2dcontour.

Updated

  • Upgraded Plotly.js, the underlying library behind the dash_core_components.Graph component, to version 1.32.0 #143. Feature release 1.32.0 includes:
    • Localization machinery, including an official German translation (locale de)
    • A new violin trace type
    • Selection improvements: selected and unselected attribute containers to customize selection states, Support for multi-selections, persistent selections.
    • colorway attribute to customize the trace-to-trace color sequence
    • Add tickformatstops to set tick format per cartesian axis range
    • And many more features and bug fixes

[0.15.5] - 2017-01-08

Fixed

  • The dash_core_components.Location and dash_core_components.Link properties should now work on Internet Explorer. Thanks to @nedned for suggesting a solution. Fixes plotly#113

[0.15.4] - 2017-12-21

Changed

  • The dash_core_components.Location component now supports hash, href, and search in addition to the already supported pathname (mimicking the window.location API). href can be used to handle pathname, hash, and search in aggregate, or each can be manipulated independently.
  • The children property of dash_core_components.Markdown and dash_core_components.SyntaxHighlighter now accepts an array of strings (previously it had to be a string). Now, if an array is provided, it is collapsed into a string with line breaks (see #134).

[0.15.3] - 2017-12-11

Fixed

  • Patched plotly.js to version 1.31.2 #125, including patch releases 1.31.2 and 1.31.1 with numerous bug fixes.

[0.15.2] - 2017-11-24

😅 Added

  • The Interval component has a new property: n_intervals. This is an integer that increases every time that the interval passes. This allows you to use the Interval component without using the events=[Event(...)] pattern inside the callback.

This is similar to the n_clicks property of the dash_html_components components. This was the last use case for events=[Event(...)] inside the dash_core_components library. Ultimately, we may be able to deprecate this pattern.

Changed

  • The dash_core_components.Input(type='number') component actually converts the values to floats or integers, instead of passing the numbers back as strings. plotly#100 Big thanks to community contributor @Madhu94!

Fixed

  • The disable_click property in the dcc.Upload component now works. plotly#106. Big thanks to community contributor @Akronix!
  • Several properties in several components had the wrong propTypes. This has been fixed, improving the documentation for the Dash python classes (and removing warnings in JS development). Big thanks to community contributor @Akronix!

[0.15.1] - 2017-11-23

Fixed

  • Attempt to fix the JS builds from 0.15.0 but actually nothing changed.

[0.11.0] - 2017-08-04

Added

  • The Dropdown component renders options much, much faster. It can render 50,000 options (client-side) without crashing! This fixes plotly/dash#103

[0.10.0] - 2017-08-03

Updated

  • Upgraded plotly.js to version 1.29.3, including feature releases 1.29.0 and 1.28.0, and patch releases 1.29.3, 1.29.2, 1.29.1, 1.28.2, 1.28.1, and 1.27.1 This includes TONS of fixes and improvements, notably:

    • Add cliponaxis attribute to scatter and scatterternary traces to allow markers and text nodes to be displayed above their subplot's axes
    • Add axis layer attribute with 'above traces' and 'below traces' values

[0.9.0] - 2017-07-28

Added

  • A config property of the Graph component that exposes the plotly.js config properties. Here's an example that hides 2 buttons and makes the elements in the graph "editable":
import dash
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash()

app.layout = html.Div([
    dcc.Graph(
        id='my-graph',
        figure={'data': [{'x': [1, 2, 3]}]},
        config={'editable': True, 'modeBarButtonsToRemove': ['pan2d', 'lasso2d']}
    )
])

if __name__ == '__main__':
    app.run_server(debug=True)

[0.8.0] - 2017-07-27

Added

  • A new Textarea component for displaying the simple Textarea HTML element. The content of the Textarea is controlled through the value property:
dcc.Textarea(id='my-text-area' value='''
SELECT * FROM MY_TABLES
LIMIT 10;
''')

[0.7.1] - 2017-07-24

Fixed

  • Clearing a Graph selection box sets the selectedData value to None (null in JavaScript). Before, it didn't change the selectedData property, preventing the user and the Dash developer from clearing selections. Fixes plotly/dash#97, thanks to @pmbaumgartner for reporting.

[0.7.0] - 2017-07-20

Added

  • The clearable property to the Dropdown, which toggles on and off the "x" on the side of the dropdown that clears the current selection.
  • The searchable property to the Dropdown, which toggles on and off whether the Dropdown is searchable.

Fixed

  • Clicking on the little x on the side of the Dropdown to clear the currently selected value didn't work. Now it does. If multi=false, then null (or Python's None) is set. If multi=True, then [] is set.

[0.6.0] - 2017-07-18

Added

  • The Slider and the RangeSlider component can update when the user finishes dragging the slider rather than just while they drag. The default behaviour has remained the same (updates while dragging) but you can toggle that the updates only get fired on "mouse up" by setting updatemode to 'mouseup' ('drag' is the default).
  • A Link and Location were added. Location represents the address bar of the web browser and Link provides a way to modify the address bar without refreshing the page. Combined, these two components can be used to create a "single page app" with multiple URLs. That is, apps that have mulitple URLs but surfing between the different pages doesn't trigger a full page refresh like it would with traditional links.
  • Previously, if callback functions weren't supplied to a component, it wouldn't update. This caused a lot of confusion: users would create a simple layout without any callbacks and then wonder why the sliders wouldn't slide or the text inputs wouldn't update. Now, all of the components manage their own state and their appearance will update regardless of whether Dash has assigned a callback to them.

[0.5.3] - 2017-07-03

Added

  • A range object is now included in the selectedData object that specifies that dimensions of the selected region.
  • A lassoPoints object is now included in the selectedData object that provides coordinates of the lassoed region.

[0.5.2] - 2017-07-03

Added

  • A new property clear_on_unhover on the Graph component will clear the hoverData property when the user "unhovers" from a point if True. If False, then the hoverData property will be equal to the data from the last point that was hovered over. The default is False.
