Hi there,
Since the December update to plotly.js the charts embedded on our webpage aren’t rendering properly.
As an example, see http://www.hefce.ac.uk/analysis/HEinEngland/undergraduate/.
When the page loads, these charts are blank and squashed with not data included. The Chrome console is showing errors of the following form:
32645b6ca510.js:1 Error: attribute height: A negative value is not valid. ("-30")
i @ 32645b6ca510.js:1
It is possible to get the chart to display by dragging on the chart area and using the Box Selection.
We have >50 charts on our webpage and could really do with some advice on how to make sure they’re displaying properly.
