Change Log for dash-core-components

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

[0.38.1] - 2018-11-14

Fixed

  • The issue #115 with datepicker, which didn't appear when the date value is None was fixed. By default, current month would appear in such cases for DatePickerRange and DatePickerSingle components. See pull request plotly#201.
  • Refactored the way the Graph component would generate an unique id if none provided.
  • Default CSS imported via style-loader is now placed at top, so that user supplied CSS can overwrite it, fixes #380

[0.38.0] - 2018-11-07

Fixed

  • Changed the way the default CSS files for some components are loaded to being loaded with webpack instead of as dependencies.

[0.37.2] - 2018-11-07

Changed

  • Updated react-select to version 2.1.0

[0.37.1] - 2018-11-07

Added

  • Added clickannotation event to dcc.Graph. See plotly#182.

Added

  • Unit tests for Input component.

Changed

  • min and max prop now won't update the input when values are lower than or greater than min and max respectively. Fixes#173

[0.20.0] - 2018-03-01

[0.19.0] - 2018-02-11

Changed

  • PropTypes now uses prop-types package instead of React to support move to React 16+

[0.18.1] - 2017-01-25

Added

Changed

  • With the plotly.js upgrade, the old polar trace types (scatter with (r, t) coordinates, bar with ((r, t) coordinates and area) are now deprecated).

Fixed

[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.

[0.16.0] - 2017-01-11

Added

Fixed

Here the bug fixes in the Graph component brought to you by the plotly.js release. See https://github.com/plotly/plotly.js/releases/tag/v1.32.0 for the official notes.

[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

[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.

[0.9.0] - 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.
