v47.0.0: Plum High Wire

Major release issued on February 18th, 2019. 🌑 [Subtitle, what characterize the week?] 🌑

Breaking changes

Warning

Breaking Changes! Only for our HTTP API consumers.

The POST <small_app>/slide_data response format has changed. Now, the data array is nested under the data property. The response looks like: {     "data": <data array>,     "meta": <other useful information>   }

  • The <small_app>/comments response properties slightly changed: slide_name has been renamed story_name and _id.$oid is now just id.

New features

Charts

  • On phones, sparklines are zoomed on touch for easier exploration
  • Waterfall: a minimum width is applied to bars when drilling
  • Heatmap: custom square sizes are capped on mobile, to ensure a nice display
  • Bulletchart: highlight only the label, not the bar

Shipping

  • Shipping now uses ansible v2.7.8

Studio

  • New design during story edition! Placeholders for charts, filters and requesters are slicker.
  • Handle invalid default for checkboxes filter
  • In dataset viewer, extra whitespaces are correctly displayed, and are underline so you won’t miss them anymore

UX

  • “Add to home screen” helper on Safari mobile: we now incitate with a popup iOS mobile users to install the app on their home screen
  • Performance: code has been greatly modularized, so users loads only charts and feature they actually need across their navigation in a small app
  • Performance: requesters values are deduplicated by our back-end, so users only fetch once the available choices (this can greatly reduce the amount of loaded data)

Bug fixes

Charts

  • Timeline: better display on mobile with many events
  • Landscape mode: works correctly in Safari (iOS) standalone mode
  • Horizontal barchart: entering animation has been rework so bars appears from the bottom without colliding existing ones

  • Tablechart: expanded images appear on click
  • Horizontal barchart: adjust variation legend and sparkline legend
  • Mapchart: Remove previous data from legend when empty data is selected

New home

  • Tile image: images are now centered

Studio

  • Chart properties configurable in dropdown (like sort) can be toggled with a checkbox
  • Applying multiple filtering/renaming transformation to a dataset now correctly updates its query in the side panel
  • Assets upload information is correctly displayed on Firefox
  • Prevent the filter key to be added to requesters config when editing them in the studio
  • Story visibility on studio works with all types of reports
  • Suggestions for dataset and column names are back when editing value tiles

UX

  • Requesters: the default id contains only authorized characters (no hyphens)

  • Stackedbarchart: prevent packs overlap
  • Home: prevent tiles to overlap with the menu gutter on the left
