Adding windrose charts to subplots in plotly dashboard


I am attempting to create a dashboard in Plotly using the ‘make_subplots’ function from

from import make_subplots
template = make_subplots(rows = 4,
                         cols = 4, 
                         specs = [[{'colspan':4}, None, None, None],
                                  [{'colspan':4}, None, None, None],
                                  [{}, {}, {'colspan': 2, 'rowspan': 2}, None],
                                  [{}, {}, None, None]]

To add bar charts and scatter plots it’s straightforward;

template.append_trace(bar_chart, 1, 1)

But when attempting to add my wind rose chart in the same way I get the following error;

ValueError Traceback (most recent call last)

Is it possible to add wind rose charts to the subplots in a dashboard?

That one is for #api:python

Hi @charlie.plot,

Unfortunately the make_subplots command doesn’t support polar plots right now. See Feel free to give this issue a thumbs-up to help inform out priorities in the future.

In the meantime, here’s an example of creating subplots without the make_subplots function.

It’s a bit more verbose, but also more flexible and this approach works with all trace types. To set the domain of the polar subplot you would use fig.layout.polar.domain.

Hope that helps get you started!

Okay, so I’ve been exploring the ‘domain’ route of getting wind rose charts as subplots. From what I can tell, to use fig.layout.polar.domain you need to assign each chart a name using the ‘subplot’ label like in the example here;

However when I tried that with my wind rose plots I get this error.

ValueError: Invalid property specified for object of type plotly.graph_objs.Area: ‘subplot’

Valid properties:
        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
        Sets the source reference on for  customdata .
        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.
        Sets the source reference on for  hoverinfo .
        plotly.graph_objs.area.Hoverlabel instance or dict with
        compatible properties
        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.
        Sets the source reference on for  ids .
        Sets the legend group for this trace. Traces part of
        the same legend group hide/show at the same time when
        toggling legend items.
        plotly.graph_objs.area.Marker instance or dict with
        compatible properties
        Sets the trace name. The trace name appear as the
        legend item and on hover.
        Sets the opacity of the trace.
        For legacy polar chart only.Please switch to
        "scatterpolar" trace type.Sets the radial coordinates.
        Sets the source reference on for  r .
        Array containing integer indices of selected points.
        Has an effect only for traces that support selections.
        Note that an empty array means an empty selection where
        the `unselected` are turned on for all points, whereas,
        any other non-array values means no selection all where
        the `selected` and `unselected` styles have no effect.
        Determines whether or not an item corresponding to this
        trace is shown in the legend.
        plotly.graph_objs.area.Stream instance or dict with
        compatible properties
        For legacy polar chart only.Please switch to

        Sets the source reference on for  t .

        Determines whether or not this trace is visible. If
        "legendonly", the trace is not drawn, but can appear as
        a legend item (provided that the legend itself is

I’m starting to think that there is no functionality for getting wind rose charts (like the one on this page) in subplots - I can’t find a single example online and have been playing round with it myself for hours. :frowning: I did however get my scattergeo working in a subplot though which was some progress!

Hi @charlie.plot,

I see what mean. The trouble you’re running into is the the Area trace is an old trace type that doesn’t use the new polar framework that’s used by scatterpolar. Fortunately, we just released the successor, the barpolar trace. This was released in 3.3.0 last week.

The documentation for the Wind Rose example itself should be updated to use barpolar very soon. In the mean time, check out the release notebook I put together for the 3.3.0 release ( barpolar traces have the subplot parameter just like scatterpolar, so they can be subplotted just like the scatterpolar traces in

Hope that helps!
