Bugs related to Vis

[puehringer]

• Zoom is enabled on violin plot
• Bar chart > Mulitples is empty dropdown
• Scatter plot > clicking away Sepal length simply switches positions (because it is readded again immediately?)
• Select hex bin > select hex bin > vis is gone
• Hex bin > labels of Setosa, ... are barely readable
• Scatterplot > All labels are shown despite mode being "selected" only. This creates a very overloaded visual

• Hex bin -> zoom is actually calculated incorrect (taking the margins into account). This has the effect that when you zoom on a hex you always miss it
• Hex bin -> the legend is misleading (at least for me). I think the color is taken from lineup instead of the plot (see image)

The merged PR #267 addressed only a single point from the list. I reopened the issue to continue with the remaining points.

• The select dropdowns in the sidebar need to be scrollable
  
• The axis labels are not consistent across plot types (color, size, font family)
• switches are inconsistent in size:
