# Plotly, scatter plot: what are the possible options for the dash entry in the line dictionary?

For example using some code like this one:

fig.add_scatter(x=x, y=y, mode='lines', line=dict(dash='dot'))


The possibilities I know of are 'lines', 'dash', 'dot' and 'dashdot'. I was looking for another way to differentiate a new plot using this option, like "spaced dots" for example. Unfortunately I couldn't find anything where I looked (basically web searches and plotly line chart documentation). Is there any other possible value for this argument or is that all there is?

When I put an invalid value to the 'dash' property, plotly shows an error message that list all the admissible values:

The 'dash' property is an enumeration that may be specified as:

 - One of the following dash styles:

['solid', 'dot', 'dash', 'longdash', 'dashdot', 'longdashdot']

- A string containing a dash length list in pixels or percentages

(e.g. '5px 10px 2px 2px', '5, 10, 2, 2', '10% 20% 40%', etc.)
