问题 I have the following heatmap made by Holoviews. I need to change x ticks to change the period of x ticks. [0,2,4,...] instead of [0,1,2,3,4,..] data = [(i, j, i*j) for i in range(10) for j in range(10)] hv.HeatMap(data) Change from this graph To this graph 回答1: It seems that bokeh doesn't provide such function. However you can change the doFormat function of xaxis.formatter before draw the plot. After run the following cell: from bokeh.models import CustomJS import holoviews as hv hv

问题 i want to plot my gensim-word2vec model in kind of a "word-galaxy"(like here: http://www.anthonygarvan.com/wordgalaxy/) and flashing out a single dot by entering it's name in a search field and pressing a submit-button.

This is my code: from bokeh.plotting import figure, output_file, show, ColumnDataSource from

问题 How can I add a legend to lines in Step graph example for bokeh: https://docs.bokeh.org/en/latest/docs/reference/models/glyphs/step.html I would like to have legend in 'top right' corner of plot for each line in color and style of the line.

So when I select the circle for person 1 in plot 1, this person's hours in the other plots should highlight, for my purpose as well. MWE: from bokeh.io import

问题 How can a Pandas DataFrame be shown as a Bokeh heatmap? https://docs.bokeh.org/en/latest/docs/user_guide/categorical.html#heat-maps shows some example, but trying to modify always only gave an empty plot.

Using bokeh to plot interactive pie chart in Jupyter/Python

由 巧了我就是萌 提交于 2019-12-08 06:44:39
问题 I am new to Bokeh and I would really appreciate some help in figuring out how to use Bokeh to plot a simple interactive pie chart in Jupyer/Python. I am planning to use 'CustomJS with a Python function' in Bokeh as explained at the bottom of the page here. The pie chart consists of two entries with a slider that can change the shape of one pie 'v2' inside the circle shape of (v1+v2). I have tried to follow the example in bokeh website that shows the interactivity with a sine plot, but I just

Select columns (not rows) in Bokeh Table Widget?

问题 I have a bokeh table that is linked to a plot, and is working as intended. Selecting a row in the table mutes all the non-selected rows in the plot display. However, what if someone wants to select a column, and hide all other columns in the plot? Is this possible using a bokeh widget? Or does some custom code need to be written for this feature? I have attached to code used to produce the widget table on the bokeh website, as it is the most simple example I can think of (and quickest). from

Unable to embed JSON Bokeh Plot in Django template

由 久未见 提交于 2019-12-08 05:04:32
问题 I have a script which takes uploaded data, munges it together, turns it into a plot (using Bokeh) and then exports it to a directory as JSON. At some point in the future, a user can hit the right URL and the appropriate plot should be displayed to the user as part of the HTML template. I can generate the plot. I can save it as JSON. I can get the URL to retrieve it as JSON, but I cannot get the JSON plot to render within the template. I've had a dig around the Bokeh documentation and examples
