The color ramp scale is displayed when the marker color_option is set to solid if showscale is true. It can be disabled by switching to ramp temporarily to expose the showscale option, disabling the showscale option, then switching back to solid. I think this may actually be a bug in plotly.js with how the showscale marker option is handled. https://plot.ly/javascript/reference/#scatter-marker-showscale. The documentation claims that this 'Has an effect only if marker.color is set to a numerical array.' But looking at the TRACE debugging console output in the panel I can see that even when the marker.color option set to a single color and not an array the color scale may still be displayed if showscale is true.
