add a lineplot prop to enable connecting points

[moontrip]

This is to define a type for a new lineplot prop, which will be used for VEuPathDB/web-eda#1519.

Would another way to address this be to remove the "missing data" points from the data series?

Or, alternatively, is there ever a reason to not have these lines? If not, then should we always proceed to connect points, which would obviate the need for this prop?

[dmfalke]

I see in your description of VEuPathDB/web-eda#1531 that removing the missing data is too complex.

My second question stands: can we just assume we always want points connected?

[moontrip]

@dmfalke Although I said it would be too complex, I may need to consider it depending on another ticket, VEuPathDB/web-eda#1082. I didn't look into the requirements carefully yet though.

For your second question, I think yes? 😄 That's the reason why I did set it to be true at this corresponding web-eda PR: VEuPathDB/web-eda#1531. The plotly prop should be set at data (processedData) level.

Can't tell whether @dave's question ("can we just assume we always want points connected?") is resolved or not--- @danicahelb or @d-callan, any thoughts?

@dmfalke @moontrip @chowington regarding

can we just assume we always want points connected?

No. we have agreed with @d-callan that if the data series contains 0/0 there will be a break in the line. Perhaps we should wait until mockups for VEuPathDB/web-eda#1082 are finalized and the new UI is implemented?
