Case example: I pick a dataset and choose a scatterplot and for some reason change the color scale from ordinal to linear. If I now pick a different visual model, let's say a Gantt chart, the scale will remember my last choice and start as linear.
A possible enhancement: when creating the chart, there could be a check for the variable type in the color box. If number the chart calls for the linear scale, if string for an ordinal an so on.
