Description
The following code plots a few lines with changing color (rgb):
from pandas import DataFrame
from bokeh.io import show, output_file, output_server
from bokeh.charts import Line, color
import subprocess
import time
if __name__ == '__main__':
output_file('rgb-platte.html')
df = DataFrame({'1': [0,1],
'2': [1,2],
'3': [2,3],
'4': [3,4],
'5': [4,5]})
# set color palette rgb
palette_r = [50, 100, 150, 200, 250] # changing the values for 'red'.
palette_g = 5 * [0] # keeping values for 'green' constant.
palette_b = 5 * [0] # keeping values for 'blue' constant.
palette = list(zip(palette_r, palette_g, palette_b))
# define the plot
p = Line(df, title="palette rgb", plot_width = 300, plot_height = 200, color=palette)
show(p)Result:
Now I replace output_file('rgb-platte.html') with:
# start a bokeh server
args = ['python', '-m', 'bokeh', 'serve']
server = subprocess.Popen(args)
time.sleep(1) # wait for the server to initialize
output_server('test')to use the bokeh server.
The resulting image has no colors:
