Releases · globeandmail/chart-tool

A ton of major changes with this release, including:

scatterplots
an internal memo field, which you can find above the “Data” panel
a smart data “sniffing” system when creating a new chart, which should, in most cases, be able to determine if your chart is YY-MM-DD or MM-DD-YY (and so forth), automatically set your axis prefixes and suffixes, and figure out whether you should see a line chart or bar chart by default
and, most importantly: annotations. You can now add text annotations, pointer annotations (as in, arrows), and “range” annotations (highlight a range of values along the x- or y-axis), as well as the “highlight” annotations for bar and column charts that already exist

A full rewrite of the backend, updating Meteor to its latest version, replacing outdated packages and dropping Meteor's Blaze templating system in favour of React
Using React means charts now only redraw when presentational elements change. Also means the interface will be far more extensible going forward
Adds sorting options to the archive page
Significantly improves reliability of PDF export by replacing wkhtmltopdf with puppeteer, a headless Chrome browser
Adds some smart data checking when creating a new chart with $'s or %'s, adding those to the prefix and suffix fields of the relevant axis
Moves PNG generation to use puppeteer as well, meaning PNGs will be consistent across browsers and environments going forward, and generation will be deferred to an external process
Rearchitects the PNG export overlay to include more options and a preview
Adds basic highlighting annotations for bar and column charts
Fixes a bunch of tooltip bugs
