-
dcc.Interval
will reset its timer when re-enabled. Previously, if thedcc.Interval
was disabled, it's "clock would keep running": when it was reenabled, it would fire at the nextinterval
on the previous clock's schedule, rather thaninterval
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`

orMarkdown
, the component would not render and the app would break. This is problematic because ifchildren
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.
- The
dcc.Graph
component now includespointNumbers
insideselectedData
andhoverData
if the chart type is ahistogram
,histogram2d
, orhistogram2dcontour
.
- 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
andunselected
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
- Localization machinery, including an official German translation (locale
- The
dash_core_components.Location
anddash_core_components.Link
properties should now work on Internet Explorer. Thanks to @nedned for suggesting a solution. Fixes plotly#113
- The
dash_core_components.Location
component now supportshash
,href
, andsearch
in addition to the already supportedpathname
(mimicking thewindow.location
API).href
can be used to handlepathname
,hash
, andsearch
in aggregate, or each can be manipulated independently. - The
children
property ofdash_core_components.Markdown
anddash_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).
- Patched plotly.js to version 1.31.2 #125, including patch releases 1.31.2 and 1.31.1 with numerous bug fixes.
- 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 theInterval
component without using theevents=[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.
- 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!
- The
disable_click
property in thedcc.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!
- Attempt to fix the JS builds from 0.15.0 but actually nothing changed.
- Bad build. See 0.15.2 for the correct build
- An
Upload
component! 🎉 See https://plotly.com/dash/dash-core-components/upload for docs.
- Upgraded plotly.js to version 1.31.0. This includes:
- Two huge feature releases by the plotly.js team! 👏 - 1.31.0 and 1.30.0, which contain:
- A new
table
trace type geo.center
making geo views fully reproducible- Extend lasso and select-box drag modes to
bar
,histogram
,scattergeo
, andchoropleth
trace types aggregate
transforms- And many other features and bug fixes
- A new
- Patch release 1.30.1 with bug fixes
- Two huge feature releases by the plotly.js team! 👏 - 1.31.0 and 1.30.0, which contain:
- Fixed issues related to updating the
max_date_allowed
property ofDatePickerSingle
andDatePickerRange
programmatically through callbacks - Clicking on the end date in the
DatePickerRange
will now open up the calendar to the end date (plotly#80)
- Cleaned up
DatePickerSingle
andDatePickerRange
- Non-ascii characters, like chinese characters, are now supported as
search strings in the
dcc.Dropdown
component (plotly#75)
- The
Interval
component was constantly resetting its interval on every update. Initially reported in https://community.plotly.com/t/multiple-interval-object-in-a-single-page/5699/3 - Removed the used
label
property from theSlider
component - Provide a more descriptive documentation for the
marks
property of theSlider
component
- A
disabled
property on theInterval
component will disable the interval component from firing its updates.
- Added
className
andstyle
properties to the parentdiv
s of theChecklist
,Dropdown
,Graph
andRadioItems
component. As requested in plotly#57, solved in plotly#60
- Previously, the
max_date_allowed
could not be selected. This issue has been fixed, issue first reported in https://community.plotly.com/t/solved-datepicker-in-dash/4816/10
- Previously, when the
options
of adcc.Dropdown
would change, the options would no longer be searchable. That has been fixed. Issue was originally reported in https://community.plotly.com/t/dropdown-not-searching-values-when-typing/5323/3
- Disabled portal settings on
dcc.DatePickerSingle
anddcc.DatePickerRange
whenvertical=True
.with_portal
andwith_full_screen_portal
will only apply ifvertical=False
.
- Added two new date picker components:
dcc.DatePickerSingle
anddcc.DatePickerRange
- Added support for all of the valid HTML attributes of the
Input
component. - Added support for a few more
type
values of theInput
component. The full list of valid types are 'text', 'number', 'password', 'email', 'range', 'search', 'tel', 'url', 'hidden'. Note that type values that don't have cross-browser support are not included (such asdatetime
)
- The
Dropdown
component rendersoptions
much, much faster. It can render 50,000 options (client-side) without crashing! This fixes plotly/dash#103
- 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 touch interactions to cartesian, gl2d and ternary subplots including for select and lasso drag modes
- Add support for contour line labels in contour and contourcarpet traces
- Add support for select and lasso drag modes on scattermapbox traces
- Add reset view and toggle hover mode bar buttons to mapbox subplots
- Add support for array marker.opacity settings in scattermapbox traces
- Add namelength layout and trace attribute to control the trace name's visible length in hover labels
- 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
- A
config
property of theGraph
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)
- A new
Textarea
component for displaying the simple Textarea HTML element. The content of theTextarea
is controlled through thevalue
property:
dcc.Textarea(id='my-text-area' value='''
SELECT * FROM MY_TABLES
LIMIT 10;
''')
- Clearing a Graph selection box sets the
selectedData
value toNone
(null
in JavaScript). Before, it didn't change theselectedData
property, preventing the user and the Dash developer from clearing selections. Fixes plotly/dash#97, thanks to @pmbaumgartner for reporting.
- The
clearable
property to theDropdown
, which toggles on and off the "x" on the side of the dropdown that clears the current selection. - The
searchable
property to theDropdown
, which toggles on and off whether theDropdown
is searchable.
- Clicking on the little
x
on the side of the Dropdown to clear the currently selected value didn't work. Now it does. Ifmulti=false
, thennull
(or Python'sNone
) is set. Ifmulti=True
, then[]
is set.
- The
Slider
and theRangeSlider
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 settingupdatemode
to'mouseup'
('drag'
is the default). - A
Link
andLocation
were added.Location
represents the address bar of the web browser andLink
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.
- A
range
object is now included in theselectedData
object that specifies that dimensions of the selected region. - A
lassoPoints
object is now included in theselectedData
object that provides coordinates of the lassoed region.
- A new property
clear_on_unhover
on theGraph
component will clear thehoverData
property when the user "unhovers" from a point if True. If False, then thehoverData
property will be equal to the data from the last point that was hovered over. The default is False.
