error message in IE 11 - chart does not plot

[TanyaShen-BEA]

Please see the attached screenshot of chart that doesn't render. It works in Chrome, Firefox but not in IE 11.

This is the error message:
SCRIPT5009: 'Uint8ClampedArray' is undefined.
File: plotly-latest.min.js, Line: 32, Column: 22068

Yikes.

What trace type are you trying to plot? Would you mind sharing a reproducible example?

Looks like the only place it occurs in the plotly source comes from es6-promise. See: https://github.com/stefanpenner/es6-promise/blob/9fef04c77d94b1d1ff2e65180fad96c3d806db72/lib/es6-promise/asap.js#L35

I feel like that should be typeof window.Uint8ClampedArray so that it doesn't just fail in strict mode.

Edit: Interesting… looks like their code is not strict mode, but plotly.js's browserified version is. Could that be the cause? (Could fix this in a hacky manner by adding window.Uint8ClampedArray = window.Uint8ClampedArray || undefined basically anywhere, but that's… just too ugly)

Thanks for the info @rreusser !

Interesting. We've been using that es6-promise polyfill ever since the 1.0.0 release and this is the first report we get.

Maybe es6-promise conflicts with something else on @TanyaShen-BEA 's page.

Can't reference dist files since too big, so I'm looking at this from plotly-basic.js. It looks exactly the same in v1.0.0 (well, @version 3.0.2 there, but the relevant part hasn't changed.)

Hmm… Uint8ClampedArray supported since KB2929437, which was a security update released 04/08/2014.

(Not to indicate it's any fault of yours but to get to the root of the cause,) @TanyaShen-BEA is it possible that you're using a very old version of IE11?

[krellsebastian]

I've got the same behavior.
Reproducible with the public accessible VMs of Microsoft. I've wanted to test my plots with IE10, bit seems the Win-Version is too old then?
