描述

It would be nice to plot lines of different styles, e.g. dashed, dotted, etc. to a Scattermapbox layer. The lack for this feature has been noted here How do I change the line style to dash in a scattermapbox plot?, and here How to change line shape in mapbox maps?

Currently (Plotly 5.18), the only supported line attributes are "color" and "width" . However, distinguishing lines by color is not sufficient for monochrome styled figures. In addition, certain line styles are frequently expected:

  • minor roads = dashed line
  • under construction = dotted line

研究方向
Review the scattermapbox line implementation in plotly.js source (likely in src/traces/scattermapbox/). Check how line dash is handled in other traces like scattergl. Look at Mapbox gl documentation for line dash support. No linked PRs, but there are community requests. Consider adding a 'dash' attribute to line object.
