There are no functions to do a contour overlay in bqplot. I asked Maarten how hard it is to implement this (waiting to hear back). Moving on to the second point.

Axes locking is possible with plotly and is very easy to change the current code base to this paradigm.

@astrofrog @nmearl @robelgeda @brechmos-stsci and a couple others had a discussion about BQPlot vs Plotly. My notes are here:
- T:bqplot does well with webgl for images and markers so is very fast
- N: Plotly does have webgl
- T: GJ can override image artists for bqplot to get data
- T: wants GJ to support plotly either way
- C: how much is plotly in GJ
- N: copied bqplot implementation and put plotly in, so some implemented but not a lot
- T: GJ might have changed too much
- T: plotly will have to support smart sampling (for large images)
- R: might need to ask Maarten about adding contours into bqplot
- T: could create a custom mark and then use matplotlib to create the contours (?)
- T: might be a week to get feature parity using plotly
Recommendation:
- determine how much of Maarten's time it would take to get a first pass at contours implemented in BQPlot
- short / medium term implement Plotyly functionality in glue-jupyter which @astrofrog wants to do anyway (so whether he implements or one of us continues the work @nmearl started.
Todo:
- @nmearl create a PR against glue-jupyter with the initial plotly implementation
- @hcferguson / @eteq we need to determine how much time from Maarten we will have / we can get, in particular with this type of work (the initial thought is that it might be 3-4 days [??] to get an initial implementation of contours in bqplot, alternatively, maybe a day of his time and 4-5 of a person at STScI, but then we would still have to get it merged.)

With consent of @brechmos-stsci we are closing this issue, this was information rather then implementational.
