I would like to refresh a bokeh document so i can replace old plots with new ones. However, right now i just get the new plots appended to the document so the old ones don't go away. #myfile. py from however, right now i just get the new plots appended to the document so the old ones don't go away. The answer for me was to save the state in the document instance: # the first 100 records of data. csv will be loaded immediately.

Doc. realtime_rec_ptr = 100. Import pandas as pd import numpy as np from pyproj import proj, transform import datashader as ds from datashader import transfer_functions as tf from datashader. bokeh_ext import interactiveimage from datashader. utils import export_image from datashader. colors import colormap_select, greys9, hot, viridis, inferno from ipython. core. display. As of bokeh 0. 12. 6, it is now possible to export png and svg directly from python code. Exporting pngs looks like this. Export_png (plot, filename=plot. png) and exporting svgs looks like this. Plot. output_backend = svg export_svgs (plot, filename=plot. svg) there are some optional dependencies that need to be. That is, i would like the chart to automatically update/refresh/reload at a specified interval without the need for user interaction. Ideally, i would only have to change something in myapp. py to accomplish this. Bokeh version is 0. 12. 0. Demo code copied here for convenience: Import numpy as np. I have a bokeh (v0. 11) serve app that produces a scatter plot using (x,y) coordinates from a data frame. P55, p1234), then those points will turn red on the scatter plot. Layout=row(selects, create_figure()) curdoc(). add_root(layout) curdoc(). title = color the dots. This is why i have a ‘run’ button in the.
