#holoviews — Public Fediverse posts

Sad that #holoviews STILL doesn’t wrap empty histogram bins for a log display by default like it is done in @matplotlib for ages: df.plot.hist(log=True) works but df.hvplot(logy=True) crashes with zeros not allowed (due to empty bins). And I really don’t care that the error is mathematically correct, it’s simply passing reality to insist not fixing this, and I’m convinced things like this are preventing a larger uptake of #hvplot and #holoviews.

*sigh* #bokehplots and/or #holoviews #hvplot still haven't worked out a way to do a histplot with logy=True and empty bins??? Sadness...

Как мы упростили процесс интерактивной визуализации данных в веб-приложении, используя HoloViews

Идея этой статьи родилась, когда наша команда занималась разработкой минимально жизнеспособного продукта (MVP) внутренней веб-системы, важной составляющей которой было визуальное представление данных, а именно результатов работы различных анализаторов исходного кода программного обеспечения. Из всего разнообразия библиотек визуализации в веб мы выбрали HoloViews, поскольку она в наибольшей степени соответствовала компетенциям нашей команды, костяк которой в силу специфики проекта составляли специалисты по анализу данных. Однако для успешной интеграции HoloViews в веб-приложение нам, как разработчикам, пришлось проявить и некоторую изобретательность. Мы посчитали, что имеет смысл поделиться этим опытом, поскольку в одном месте подобный материал до сих пор нигде не был собран.

Hey #spatial #R folks, is it possible to extract geometries from #ggplot as files? That is, the point, line, and polygon geometries in the graphs to #geopackage or #shapefile etc.

It is possible with #seaborn and #matplotlib, but that's Python not R. There's a nice and lightning fast #EdgeBundling technique in the newest ggplot, which is very promising for the #visualization of massive #mobility data.

There is also something in #HoloViews but I do not understand that library at all.

There is always so much more to tell. I only realized afterwards that I overlooked the new spatial and temporal unit support 🤦

But I did remember the new and improved #OGC #MovingFeatures #MFJson support and our plans for #MEOS / #MobilityDB integration

#ExploratoryDataAnalysis trick of the day: linking a scatter plot and a bar plot in #holoviews using DynamicMap (since Linked Brushing -- which is awesome usually -- does not support bar plots)

I'm so happy that we're finally in a place where we can whip up a quick trajectory data exploration app with maps and graphs from rather arbitrary inputs, be it plain old csv with x/y in any crs known to proj, or fancy gis formats in just a few minutes.

It's minimal extra effort and seems to impress most people so much more than comparable plots in a notebook 🤷‍♀️😀

TIL more about #holoviews / #colorcet / #bokeh / #matplotlib color map handling than I ever wanted to know 🤨

Hopefully, the improved #movingpandas plots will be ready soon

Did you know that @movingpandas supports plotting using custom #projections?

This #HiddenGem feature of #GeoViews is really neat and it's now featured on the update #MovingPandas homepage

Today, I had the pleasure to present @movingpandas at the #Maritime #Informatics & #Robotics - #Maritime2023 #SummerSchool

Too bad I couldn't make it there in person, but I do hope that the participants got a good impression of the #Python for #MovementDataAnalytics ecosystem:

If all goes as planned, the next version of @movingpandas will ship with improved #Trajectory plotting capabilities, including, finally: #arrow markers that show the direction of the movement

Today's success moment: came up with a hack to have arrow markers in #GeoViews 👩‍💻 while building a #visualanalytics app with @geopandas & #panel.

I'm still surprised that the built-in @bokeh markers don't include any arrows. None of the available markers can be used to unambiguously show direction https://docs.bokeh.org/en/latest/docs/examples/basic/scatters/markers.html#index-0

While working with #GeoViews, I noticed that the map zoom tool is not active by default.

I think this may be one of the main reasons why users find GeoViews less intuitive than #Folium

We can set the zoom tool active using:

from holoviews import opts
opts.defaults(opts.Overlay(active_tools=['wheel_zoom'])

Sharing an interactive tutorial on #earthquake #sonification that I built for high school students. It uses #trinket.io, #bokeh, and #HoloViews to introduce students to #python and waveform exploration. Links to #jupyter notebooks are attached to each module.

As a music nerd and fledgling #audiophile, this was such a fun project and fun way to explore seismic data!

Many thanks to Ben Holtzman for introducing me to the beauty of data sonification during my PhD 🔊
