Tooltip rendering issue

tony12624120 · July 19, 2018, 1:26pm

Hi all,

In this code the tooltip doesn’t show up for the red candles. Can someone help me with an idea why?

import pandas as pd

import numpy as np

from bokeh.models import ColumnDataSource, HoverTool

from bokeh.plotting import figure, show

from bokeh.sampledata.stocks import MSFT

source = pd.DataFrame(MSFT)[:50]

source[“date”] = pd.to_datetime(source[“date”])

source[“color”] = np.where(source.close > source.open, ‘#33AA44’, ‘#F2583E’)

plot_main = figure(x_axis_type = “datetime”, tools = “pan,box_zoom,resize,reset,save,wheel_zoom”, plot_width = 1700, plot_height = 900, title = “Candle Stick Example”, toolbar_location = “above”, active_scroll = “wheel_zoom”)

segments = plot_main.segment(x0 = ‘date’, y0 = ‘low’, x1 = ‘date’, y1 = ‘high’, color = ‘color’, source = ColumnDataSource(source), legend = “Needles”)

candles = plot_main.vbar(x = ‘date’, bottom = ‘open’, top = ‘close’, color = ‘color’, width = 12 * 60 * 60 * 1000, source = ColumnDataSource(source), legend = “Candles”)

plot_main.add_tools(HoverTool(tooltips = ‘

High: @high
Close: @close
Open: @open
Low: @low

’, show_arrow = False, renderers = [candles]))

show(plot_main)

Hi,

The code below works for me if I remove "resize" for the tools list, otherwise I get an exception. That's because the ResizeTool was removed a long time ago. There was also a time before hit-testing was added to bars, are you using an old version? It's always important to state version information with any request for help.

Thanks,

Bryan

I was using 0.12.6.
Now I upgraded to 0.13.0 and it works.

Thanks
