问题 How can I set for a CategoricalAxis not to show every ticker but just every second or third one? Let say I have 20 categorics on x-axis . I tried this but it does not work: ticker = CategoricalTicker(desired_num_ticks=10) xaxis = CategoricalAxis(ticker=ticker) my_fig.add_layout(xaxis, 'above') It shows all my tickers :( EDIT: It would be great to show only every second label as well... Thank you! 来源： https://stackoverflow.com/questions/34949298/python-bokeh-show-only-every-second-categorical

问题 I need your inputs on some challenges I'm facing since few days. My target is to have a upload button, from which I share .xlsx file with 2 sheets. Once I load this data and read it into pandas DataFrame , I perform some pythonic calculations/optimisation code etc and get few results(tabular summarised). Now based on the number of unique 'levels'/'groups' I will create that many tabs and then display this summarise results in each tab. Also have a general(common) plot in the main page. Below

问题 I'm new to Bokeh and I'm trying to create an interactive plot of weather data. There are two Select menus, one for sensor ID (132, 133, ...), and one for variable (Temperature, Dew Point, ...). When the user changes either value, the graph is supposed to update with the selected data. The data I'm using is in a Panda Dataframe, where there is a column 'dt' which contains the one minute interval datetime objects, and the data are in columns that follow the naming convention 'Temp132', 'Temp

问题 Bokeh image glyph shows images upside-down and y-axis does not conform to standards of image display, where tick mark zero starts at the top (matrix-like notation). from scipy.misc import lena import bokeh.plotting as bp import matplotlib.pyplot as plt bp.output_notebook() %matplotlib inline lena_img = lena()/256.0 plt.figure(figsize=(10, 10)) plt.imshow(lena_img, cmap='gray') plt.show() f1 = bp.figure(plot_width=512, plot_height=512, x_range=[0, 512], y_range=[0, 512], logo='grey') f1.image

问题 I would like to set the range of a datetime axis using a button. However, the command f.x_range = Range1d(start=start_date, end=end_date) doesn't work. When clicking the button nothing happens. I don't get any errors, neither in the terminal windows running the Bokeh server, nor in the console output of my Chrome web browser. You find the entire code below. I'm grateful for any advice. Thanks, Julian # Import libraries from bokeh.io import curdoc from bokeh.models import ColumnDataSource,

问题 How to assign css proprties to a custom class assigned to a widget through css_classes if I'm serving my app through bokeh serve --show ? from bokeh.models import Button button = Button(label="Press Me", css_classes=['myclass']) curdoc().add_root(button) 回答1: If you dont mind using a html template, once you define your css classes, their styles can be set in a css file.
