 # Since crosstalk's SharedData object was supplied to plot_ly() with a key of
 # patient, it knows to highlight any lines/markers matching the selected patient(s).
 # By default, the "on trigger" is "plotly_click", but we've changed that to 
-# "plotly_selected", which corresponds to click and drag mouse events.
+# "plotly_selecting", which corresponds to click and drag mouse events.
 # Plotly provides two types of drag modes that will trigger a "plotly_selected"
 # event: "lasso" and "select". You can change the dragmode interactively via 
 # the modebar and/or set the default dragmode via `layout()`.
