Plotly.js: Heatmap legend can't be disabled

[kevinwuhoo]

It seems like showlegend: false for heatmaps is broken. I found this codepen in the docs that should have the legend hidden, but it's still being rendered: https://codepen.io/plotly/pen/WQGgbe. That codepen is linked from this page: https://plot.ly/javascript/configuration-options/#modify-the-edit-chart-link-text.

I couldn't get it to work by placing showlegend: false in either the trace or the layout. I also cherry picked a few previous versions to see if this worked at some point, but couldn't find one.

Thanks for all your hard work!

That's because we don't call it a legend, we call it a colorscale, with corresponding showscale attribute.

(I don't know why that example has showlegend in it, we'll take that out... but just to be clear, showscale is a trace attribute, not a layout attribute)
