Adding a layout shape line with custom dash lenght lists is not working #3375
Description
Example:
plotly.graph_objects.layout.shape.Line(color='black', width=2, dash='5px,3px,3px,2px')
produces the following:
ValueError:
Invalid value of type 'builtins.str' received for the 'dash' property of layout.shape.line
Received value: '5px,3px,3px,2px'
The 'dash' property is a string and must be specified as:
- One of the following strings:
['solid', 'dot', 'dash', 'longdash', 'dashdot',
'longdashdot']
- A number that will be converted to a string
Moreover, the documentation and the Line docstring state that it should be allowed, but the layout.shape.Line.dash property docstring states otherwise.

Had the same issue. After looking around a bit, I found that the problem is that the DashValidator from
validators/layout/shape/lineinherits from StringValidator instead of DashValidator (same actually forvalidators/scattersmith/lineandvalidators/layout/newshape/line). Changing this line:to this:

C:\Users\[USER]\Anaconda3\Lib\site-packages\plotly\validators\layout\shape\line\_dash.pyon Windows (probably similar on Linux/Mac) fixes the issue. Not sure how to make a patch of this though.Fix layout shape line dash w/ custom lenghts plotly#3375
