- using hexbin.context([context]), hexbin.hexagon() and hexbin.mesh() support canvas ; fixes #1 - incremental updates: bins.add(point); bins.addAll(points); remove(point); bins.removeAll(points); fixes #3 - hexbin.angle([angle]) sets or reads an angle (default 0°, use 90° for flat-topped hexagons) ; fixes #8
…ifferent order) note: I made it be a setter, which sort of duplicates hexbin(data)
- remove .data(), instead use bins.flat() to get the data, and hexbin() to update without adding points. - don't rebin aggressively when changing parameters, only on update ie when calling hexbin() - all the new methods are on hexbin not on bins
Including a bit more centers solves the issue. The solution breaks a test on centers() in the angle=0 case, which we could keep backwards compatible by testing for angle===0; but I don't think it's a problem if we have a few more centers (better safe than sorry).

Wow I forgot about this. It's only been 4½ years! I might have to review the code a bit. Have you tried it? |

Less than 5 years ago should still be OK, right? 😉 |

Alternative to #17 ; in this version, changing accessors does not result in the (awkward) rebinning of already-present points.
Closes #1 #3 #5 #8 #18.
