New charts wishlist

[jackparmer]

The most requested feature in the plotly user survey has been "More chart types" 2 years in a row.

This issue inventories remaining chart types (or "traces" in plotly parlance) that are still requested for plotly.js and Chart Studio. Pipelines to make most of these charts already exists in Python and R by combining lower level plotly.js traces (lines, SVG shapes, bars, area fills, etc).

plotly.js trace types that do not exist yet

"Business charts"

• Funnel charts Example
• Stacked area charts Example
• Waterfall charts Example
• Hero numbers Example
• Gauges Example
• Bullet charts Example
• Tree maps Treemap trace #1038
• Voronoi tree maps Example & resource
• Marimekko charts Marimekko aka Mekko plot #4019
• Timeline Add new plot: timeline #2803
• Gantt charts Discussion
• Aster plots (Aster Plot Feature #2901)
• Cost curve charts Example

Geo

• County choropleths (w/o zoom for perf.) Example
• Contours on maps ("weather maps") Example
• MapboxGL heatmap support Example

Scientific

• 3d isosurface Example
• Sunbursts Example
• WebGL/regl network graphs Example Implementing as a Dash Component
• Parallel categories Example ➡️ Parallel Categories trace type for multi dimensional categorical data jonmmease/plotly.js#1
• 2d quiver plots Example
• Bagplot (and Bagplot matrix) Reference
• strip and/or swarm plots add swarm plot #4021
• Chord diagrams Chord diagrams #3942

The most requested feature in the plotly user survey has been "More chart types" 2 years in a row.

How about

• Mapping data to subplots ("faceting") as in the create_facet_grid figure factory: https://plot.ly/python/facet-plots/ Moved this one to the Python layer in plotly.express with facet_row and facet_col

[monfera]

Added some technical notes on parcoords, parsets, sankey here: #2229

Star Coordinates: http://people.cs.vt.edu/~north/infoviz/starcoords.pdf

There doesn't seem to be any JS support for it, and it would be a nice complement to SPLOM and ParCoords ;)

[jackparmer]

Some nice progress recently in adding plotly.js trace types to the online chart editor (https://plot.ly/create/):

Very easy way to try out these chart types before coding.

• profiler graphs feature: function profiling graphs #3878
• force-directed-graph Implement of force-directed-graph of d3 #3883

[kiranshila]

Happy to see the maintainers looking into Smith Charts. I've been working on this for some time and will be able to submit a PR soon.

[etpinard]

• facet / trellis from [feature request] - facet / trellis plot option #4248

How about waffle charts?

hexbin / hexagonal heatmaps - from @mafar in #4368

[jdb78]

Are there any plans to support stacked waterfall charts directly (e.g. here), i.e. not with the workaround of stacking different bars? Along with gantt charts this is a very common chart type in business environments that is currently not supported by plotly.

BTW: I love all the hard work you are putting into development. The plotly packages really make a difference on a daily basis.

[nicolaskruchten]

@jdb78 we’re open to the idea but it’s not clear how to support stacked negative values in the general case...

[nicolaskruchten]

I should clarify: it’s not clear how to handle stacks of mixed positive and negative values :)

[jdb78]

As this is a edge case in reality, can we not just throw an exception? I know this is unsatisfying but for 99% of applications a combination of negative and positive values is not a valid case.

[nicolaskruchten]

@jdb78 lets continue this conversation in #4450 ?

[cherepanovic]

any news to #3259 (comment)?

This issue has been tagged with NEEDS SPON$OR

A community PR for this feature would certainly be welcome, but our experience is deeper features like this are difficult to complete without the Plotly maintainers leading the effort.

Sponsorship range: $25k-$30k (per new chart type)

What Sponsorship includes:

• Completion of this feature to the Sponsor's satisfaction, in a manner coherent with the rest of the Plotly.js library and API
• Tests for this feature
• Long-term support (continued support of this feature in the latest version of Plotly.js)
• Documentation at plotly.com/javascript
• Possibility of integrating this feature with Plotly Graphing Libraries (Python, R, F#, Julia, MATLAB, etc)
• Possibility of integrating this feature with Dash
• Feature announcement on community.plotly.com with shout out to Sponsor (or can remain anonymous)
• Gratification of advancing the world's most downloaded, interactive scientific graphing libraries (>50M downloads across supported languages)

Please include the link to this issue when contacting us to discuss.

Are there any plans to make Gantt available for js?

[ctooley21]

Following up on this, Gantt charts would be a great addition to Plotly.js.

[Zaffer]

Indicator Traces are missing from Chart Studio. Please add 🙏🏼

[evbo]

What about adding support for 2D/3D Network Graphs in Plotly JS? Currently available in Python...

[Michael-Barletta]

Any update on "Contours on maps ("weather maps") "?

[gvwilson]

closing as most of these requests are covered by other issues
