Question Below code is grouped vbar chart example from bokeh documentation. There are something i can't understand on this example. Where 'cyl_mfr' is come from in factor_cmap() and vbar()? 'mpg_mean' , is it calculating the mean of 'mpg' column? if then, why 'mpg_sum' doesn't work? I want to make my own vbar chart like this example. Code from bokeh.io import show, output_file from bokeh.models import ColumnDataSource, HoverTool from bokeh.plotting import figure from bokeh.palettes import Spectral5 from bokeh.sampledata.autompg import autompg_clean as df from bokeh.transform import factor_cmap

The following code doesn't generate a graph: import pandas import numpy as np from bokeh.plotting import figure, show, output_file from bokeh.io import output_notebook from datetime import datetime output_notebook() TOOLS="hover,crosshair,pan,wheel_zoom,zoom_in,zoom_out,box_zoom,undo,redo,reset,\ tap,save,box_select,poly_select,lasso_select," df = pandas.read_csv('./logs.csv') df['datetime'] = pd.to_datetime(df['datetime']) xvals = df['datetime'].dt.strftime('%Y-%m-%d') yvals = df['datetime'].dt.strftime('%H:%M:%S') p = figure(title="Test Title", width=500, height=500, \ x_axis_type="datetime"

In the following set up, I create a area chart based on the basic example. How do I get the legend for my input automatically or even programatically. For now I get only legend with one item 'a' and the first color. from bokeh.plotting import * ... patches([x2 for a in areas], list(areas.values()), color=colors, alpha=0.8, line_color=None, legend='a', title="hello chart") legend().orientation = "top_right" # what other options, may here? show() What is the format to pass into patches for the legend as value or how can I trigger the legend() to show an item and color for every item in the plot?

Hello, I have a problem with Bokeh library. I need make a legend box outside plot area. It works for circle and area plotting. I can't find the solution for the stacked bar.With the solution below the legend shapes one part of the graph, it isn't acceptable (see link under the code).I would like a legend in the box. Regards, SR import numpy as np from bokeh.layouts import gridplot from bokeh.models import ColumnDataSource, NumeralTickFormatter,LinearAxis, Range1d, Legend from bokeh.plotting import show, output_notebook, figure from bokeh.core.properties import value from math import pi output

How can I re-generate this example toggling between linear and log scales? Background: I'm a long-time Matplotlib user, recent Bokeh user. One of the main reasons I have started using Bokeh is because of the interactiveness it provides. A big part of it would be the ability to toggle between linear and log scales in plots (which is something I really need in my daily life). This question was adressed here in 2015 and at the time there was no clear answer. However, it's 2 years later and I'm wondering if there's a way to include a button/widget to change from linear to log scale for both the x

The other day, I asked about how to control tickers: How to show only evey nth categorical tickers in Bokeh Now I need to supply n from outside of Coffeescript, where n is the every n-th ticker. Based on the code snippet provided by bigreddot and by referring to the code examples shown below links: https://bokeh.pydata.org/en/latest/docs/user_guide/extensions_gallery/widget.html#userguide-extensions-examples-widget How do I use custom labels for ticks in Bokeh? I came up with the following very minimal code although I don't have knowledge about Coffescript. In fact, however, it does not work.
