daattali / accordion_reprex
Last active Jun 20, 2019 — forked from geebioso/accordion_reprex
This code creates deletable dynamic accordions that load a modal when they are created. The modal is triggering too many times after an accordion is deleted and then reloaded.

View plotlyclicklasso.R
# Clicking on a single point seems to clear the lasso selection. But the opposite is not true: doing a lasso selection still keeps the clicked point information.
# To reproduce:
# - Click a single point
# - Do a lasso selection
# - Both are currently visible
# - Click a different point
# - Now the lasso selection information is gone
# - Do a lasso selection again, both are visible again
View plotlycurvenumber.R
# I'm trying to let the user select points and paint them in a certain colour, and if the user clicks on a point then paint that point a different colour.
# It looks like the pointNumber and curveNumber data that plotly returns are different for the same points. I'm not sure how curveNumber works, but to me it doesn't make sense yet :)
# Any help is appreciated!
