Hey. I’m trying to retrieve the
geometry dict from the
selectiongeometry event but I can’t find a way to do it.
p = figure(plot_width=1100, plot_height=500, tools="xpan, save, zoom_in, zoom_out, ypan", x_range=(0, 100), tooltips=TOOLTIPS) p.line(x='x', y='y', source=s1, color="blue", line_width=1, line_alpha=0.4) stats = PreText(text="", width=500)
I already managed to update the PreText upon selection, but I would like to get the start and end (x0, x1) coordinates in order to retrieve that data based on the selection coordinates
stats = PreText(text="", width=500) def update_stats(event): stats.text = "selection event." p.on_event('selectiongeometry', update_stats) r1 = row(p, stats) c1 = column(peek) c2 = column(r1, c1) curdoc().add_root(c2)
Maybe there is another way to get the and store the selected data?
