We use the order of the dimensions on the array for choosing how to plot it. The analogous behavior would be to always plot longer dimension along the x-axis, which isn't what we do.

> The current behaviour for a 10000x3 array is to plot 10000 lines which is bad. I'm OK with adding an error message but strongly feel that choosing to plot 3 lines (i.e. always smallest number of lines) is a good default.

I agree that users probably rarely want 10,000 lines :). That's a good reason to require an explicit choice here.

The problem are edge cases like a 5x6 array. Do you want 5 lines of 6 points each or 6 lines of 5 points each? If we make the heuristic depend on the size of the array, then it will give very hard to understand what happens when the array shape changes slightly.

> Re:error, would that be a message stating that either x or hue be specified if the input is 2D?

Yes, that sounds right.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,282339218

So if you have a 10000x3 DataArray, this will plot 3 lines instead of 10000.

I am very nervous about automated heuristics for choosing behavior. I would much rather we raise an error message in cases like this, rather than guessing.
