bokeh serve running but can't access with browser

阅读更多关于 bokeh serve running but can't access with browser

问题 I have installed bokeh and downloaded myapp.py from the official page (http://docs.bokeh.org/en/latest/docs/user_guide/server.html) which looks like this. # myapp.py from random import random from bokeh.layouts import column from bokeh.models import Button from bokeh.palettes import RdYlBu3 from bokeh.plotting import figure, curdoc # create a plot and style its properties p = figure(x_range=(0, 100), y_range=(0, 100), toolbar_location=None) p.border_fill_color = 'black' p.background_fill

Bokeh hover tooltip not displaying all data - Ipython notebook

阅读更多关于 Bokeh hover tooltip not displaying all data - Ipython notebook

问题 I am experimenting with Bokeh and mixing pieces of code. I created the graph below from a Pandas DataFrame, which displays the graph correctly with all the tool elements I want. However, the tooltip is partially displaying the data. Here is the graph: Here is my code: from bokeh.plotting import figure, show from bokeh.io import output_notebook from bokeh.models import HoverTool from collections import OrderedDict x = yearly_DF.index y0 = yearly_DF.weight.values y1 = yearly_DF.muscle_weight

Displaying only one tooltip when using the HoverTool() tool

阅读更多关于 Displaying only one tooltip when using the HoverTool() tool

I am plotting very many points in Bokeh, and I have added the HoverTool to the list of tools of the figure, so that the mouse shows the x,y coordinates of the mouse when close to a glyph. When the mouse gets close to a set of glyphs closely packed together, I get as many tooltips as glyphs. I want instead only one tooltip, the one of the closest glyph. This isn't just a presentation detail, because for very many points this results: in slow interaction with the plot, with the browser getting stuck while all tooltips are generated in a very long tooltip, where the same information is repeated

How to add data labels to a bar chart in Bokeh?

阅读更多关于 How to add data labels to a bar chart in Bokeh?

问题 In the Bokeh guide there are examples of various bar charts that can be created. http://docs.bokeh.org/en/0.10.0/docs/user_guide/charts.html#id4 This code will create one: from bokeh.charts import Bar, output_file, show from bokeh.sampledata.autompg import autompg as df p = Bar(df, 'cyl', values='mpg', title="Total MPG by CYL") output_file("bar.html") show(p) My question is if it's possible to add data labels to each individual bar of the chart? I searched online but could not find a clear

Bokeh Plotting: Enable tooltips for only some glyphs

阅读更多关于 Bokeh Plotting: Enable tooltips for only some glyphs

问题 I have a figure with some glyphs, but only want tooltips to display for certain glyphs. Is there currently a way to accomplish this in Bokeh? Alternatively, is there a way to plot two figures on top of each other? It seems like that would let me accomplish what I want to do. 回答1: Thanks to this page in Google Groups I figured out how this can be done. Link here Edit 2015-10-20 : looks like the google group link doesn't work anymore unfortunately. It was a message from Sarah Bird @bokehplot.

Serving interactive bokeh figure on heroku

阅读更多关于 Serving interactive bokeh figure on heroku

I'm trying to serve an interactive bokeh figure via heroku. The figure I'm trying to have served is essentially equivalent to this one ( example , code ). I'm new to both bokeh and heroku so I'm pretty sure I'm missing something pretty basic -- I think what I'm trying to do should be quite straightforward. First, I can serve my figure locally using the bokeh serve --show myapp command. Where myapp is the name of the python module that includes the bokeh figure. Note that the --show flag just prompts bokeh to open a browser window once the figure is built and the server is running. Next, I've

Streaming two line graphs using bokeh

阅读更多关于 Streaming two line graphs using bokeh

问题 I would like to create a visualization where there are two line graphs which are updated with one new point per line graph per second. The result will be something like this. I have recently read about bokeh and found out that it can be used in visualizing streams of data in real time. However don't know how to code in it yet. I would appreciate it if someone can show me how this task can be done using bokeh. thanks! 回答1: For bokeh-0.11.1 : Basically, you need to run you python app in the

Data tooltips in Bokeh don't show data, showing '???' instead

阅读更多关于 Data tooltips in Bokeh don't show data, showing '???' instead

I'm trying to create a stacked bar chart using Bokeh. I'd like to use the hover feature, displaying the relevant data in each part of the bar, but instead of the data Bokeh shows '???'. I got the data in an excel file called "Example worksheet", in a sheet called "Sales". The sheet looks like this: Year Category Sales 2016 A 1 2016 B 1 2016 C 1.5 2017 A 2 2017 B 3 2017 C 1 2018 A 2.5 2018 B 3 2018 C 2 I tried running the following code: import numpy as np import scipy as sp from bokeh.charts import Bar, output_file, show from bokeh.models import HoverTool import pandas as pd x = pd.read_excel(

Position the legend outside the plot area with Bokeh

阅读更多关于 Position the legend outside the plot area with Bokeh

问题 I am making a plot following the example found here Unfortunately, I have 17 curves I need to display, and the legend overlaps them. I know I can create a legend object that can be displayed outside the plot area like here, but I have 17 curves so using a loop is much more convenient. Do you know how to combine both methods? 回答1: Ok, I found the solution. See the code below where I have just modified the interactive legend example: import pandas as pd from bokeh.palettes import Spectral4 from

In Bokeh, how do I add tooltips to a Timeseries chart (hover tool)?

阅读更多关于 In Bokeh, how do I add tooltips to a Timeseries chart (hover tool)?

问题 Is it possible to add Tooltips to a Timeseries chart? In the simplified code example below, I want to see a single column name ('a','b' or 'c') when the mouse hovers over the relevant line. Instead, a "???" is displayed and ALL three lines get a tool tip (rather than just the one im hovering over) Per the documentation ( http://docs.bokeh.org/en/latest/docs/user_guide/tools.html#hovertool), field names starting with “@” are interpreted as columns on the data source. How can I display the
