Invalid heatmap values

[workerclass]

This heatmap shows that my values are (15, 22.75), (22.75, 28), (26, 11), the first two are wrong.

Yes, you're right - thanks! We don't handle nonuniform brick sizes correctly. We've labeled the center of the brick, but as the brick boundaries are drawn halfway between adjacent data values, the brick center is not the same as the data values that created the brick in the case of nonuniform bricks.

Actually the problem is deeper than just hover labels - consider what happens when you set zsmooth: 'best' in that same plot (that triggers automatic connectgaps) - you can see that the color is ascribed to the brick center as well, and not to the data point as desired.

And it spills over into contour traces too: the contour lines themselves are fine, as are the hover labels, but coloring: 'heatmap' puts the colors in the wrong places again.

Any ETA on when this will be fixed?

[LarryMartell]

Looks like the same bug exist with a contour map as well.

[LarryMartell]

Does this mean it is fixed? How can I get the latest code with the fix?

[alexcjohnson]

v1.33.1 will be published later this afternoon including this fix. Until then you can build your own bundle from the master branch.

[LarryMartell]

That is great. I will wait for 1.33.1. Can you let me know when it's available for download?

[alexcjohnson]

We hit a snag actually publishing to npm and our CDN (may not happen until Monday), but if you just want the built files, these have been updated and you can download them from https://github.com/plotly/plotly.js/tree/master/dist
