Hi all,
For teaching purposes, I’m trying to convert my Processing tutorial into python bokeh. The original is available at vda-lab.org/blog/hands-on-data-visualization-using-processing/. One particular issue I have is trying to do brushing and linking between 2 plots of different lengths. The data concerns flight information: which planes leave from which departure airports to which arrival airports. Of course one departure airport is linked to multiple arrival airports (see screenshot attached).
The following does not work:
source = ColumnDataSource({
departure_longitude = [1,2,3],
departure_latitude = [4,5,6],
arrival_longitude = [[1,2],[3,4,5],[6]],
arrival_latitude = [[9,8],[7,6,5],[4]]
})
In this small dataset, there are 3 departure airports, with dummy geographic locations. The first departure airport (at (1,4)) has flights to 2 arrival airports, the second to 3, and the third to only one arrival airport.
Any help to getting this one-to-many linking-and-brushing working would be much appreciated. Thank you,
jan.
