Hover = HoverTool(tooltips=None, mode='vline') Legend_label : the legend entry for the circle # selection and non-selection symbols Size : the size of the circle (in screen space or data space units) Line_color : the fill color of the outline of the circle P2.multi_line(pd.DataFrame(,]),ĭifferent renderer functions accept various parameters to control the appearance of glyphs.įor example, use circle() to define the color or diameter of the circle:įill_color : the fill color of the circleįill_alpha : the transparency of the fill color (any value between 0 and 1) Add and customize renderersīokeh's drawing interface supports many different glyphs, such as lines, bars, or other polygons. P1 = figure(plot_width=300, tools='pan,box_zoom') Use the figure() function to create diagrams. You can also do it manually: import numpy as npĭf = pd.DataFrame(np.array(,įrom bokeh.models import ColumnDataSourceĬolumnDataSource is Bokeh's own data structure. bokeh automatically converts these lists into ColumnDataSource objects. Data preparationĭata sequences such as Python lists and NumPy arrays are used to pass data to bokeh. This time, the practical middle-level interface otting draws graphics 1. Models : low-level interface, providing developers with maximum flexibility Plotting : middle-level interface, used to assemble graphic elements P.line(x, y, legend="Temp.", line_width=2)# Step 3Ĭharts : high-level interface, drawing complex statistical charts in a simple way P = figure(title="simple line example", # Step 2 Python list, NumPy array, panda's data basket, etc. Polar coordinate diagram of biological bacteriaīasic steps for drawing interactive graphics with bokeh: The drawing interface is centered around two main components – data and symbols.īefore we start, let's appreciate the beauty of bokeh graphics: Periodic Table of Chemical Elements The goal of Bokeh is to provide an elegant, concise and novel graphical style using the D3.js style, while providing high-performance interactive functions for large datasets.īoken can quickly create interactive plots, dashboards and data applications. īokeh, a Python interactive visualization library, supports high-performance visual representation of large datasets in modern web browsers.
