问题 I have created a simple Bokeh app that runs successfully via bokeh serve. I was then asked whether it could be re-deployed using HTTPS instead. The client already has an SSL certificate, and the app is only accessed within their intranet. Most search results are for deployments behind a proxy server like Apache or Nginx. Are those required for us to setup SSL? Can it be done on Bokeh natively? 回答1: Bokeh Server does not have any SSL capability built in. If you want that, you will need to

问题 my following visualization needs a play button to automatically go through the values on the slider and loop when reaches the end. Is there a way to achieve that? Thanks. The expacted outcome is like the graph on this link: https://demo.bokeh.org/gapminder # Bokeh Visualisation (0.12.7) from bokeh.charts import Scatter, output_file, show from bokeh.plotting import figure, output_file, show, ColumnDataSource from bokeh.io import output_file, show from bokeh.layouts import layout, widgetbox,

问题 I'm trying to create a simple bokeh server application that allows a user to load a file from a <input type="file"> file selection button. The app will then plot the data from the file that the user selected. The code below is very simplistic, and I simply don't know how to pass the file information from the file selector to python. I need to use python to handle the file I/O and not html or javascript. I can get it to work just fine when I run bokeh serve --show example.py path/to/input_file

问题 How can I center an embedded Bokeh plot? My css seems to have no effect on Bokeh's <div class="plotdiv"> . In the minimal example below, I want the plot to be at the center of the yellow container. from jinja2 import Template from bokeh.embed import components from bokeh.models import Range1d from bokeh.plotting import figure from bokeh.resources import INLINE from bokeh.util.browser import view x1 = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] y1 = [0, 8, 2, 4, 6, 9, 5, 6, 25, 28, 4, 7] p1 = figure

问题 I want to make a bar chart of some simple data, e.g. a pandas dataframe like this. Cats 4 Dogs 3 Mice 27 I would like a tooltip which displays something like this when hovering over a bar: Name: Cats Count: 4 With a bar chart, this worked with hover.tooltips = [ ('Name', ' $x'), ('Count', ' @height'), ] I since switched to vbars. What would be the corresponding keyword for @height? Or does it generally not work this way with vbars/hbars? 回答1: I figured it out. I could make an extra

问题 I have some difficulties to use the Widget callback with Bokeh. With the help of a checkbox widget, I would like to show/hide the corresponding plots. The difference with this question, is that I would like a plot for each glyph(and not all the glyphs on one same plot). For example, if I tick/untick "b" I would like to see a new plot of the glyph. Edit: New version of my code from bokeh.io import output_file, show from bokeh.layouts import column, widgetbox, row from bokeh.models import

问题 I am attempting to add a simple text string (glyph) to a Bokeh plot which uses x_axis_type='datetime' My code (stripped to its essentials ) is as follows: p = figure(plot_width=900, plot_height=380, x_axis_type='datetime') dt = date(2003, 3, 15) p.line(xvals, yvals) txt = Text( # x=some_formatting_function(dt), x=1057005600000, y=0.1, text=["happy day!"], text_align="left", text_baseline="middle", text_font_size="11pt", text_font_style="italic", ) p.add_glyph(txt) show(p) The x-axis range

问题 Can the line_dash parameter of a segment plot depend on the source data? data = {} data["dash"] = ["dashed","dashed","solid"] data["x0"] = [0,1,2] data["x1"] = [5,6,8] data["y0"] = [1,1,1] data["y1"] = [2,1,2] source = bokeh.models.ColumnDataSource(data) plot.segment(x0="x0", y0="y0", x1="x1", y1="y1", line_dash="dash", source=source) Returns ValueError: expected an element of either Enum('solid', 'dashed', 'dotted', 'dotdash', 'dashdot'), Regex('^(\d+(\s+\d+)*)?$') or Seq(Int), got 'dash'

问题 In my Bokeh server based project I have to use/add a few images that are within the Bokeh project folder. I created a static folder called "static/" within the project folder and basically my code looks like this: div_img_html = "<img src='static/image.png'>" div_img = Div(text = div_img_html) however when running the server I get: 404 GET /static/image.png (::1) 2.00ms Obviously Bokeh gets the Div command however server doesn't know how to retrieve the actual file.... The actual file
