Python Bokeh – 在图上绘制补丁
Bokeh 是一个Python交互式数据可视化。它使用 HTML 和 JavaScript 渲染其绘图。它针对现代 Web 浏览器进行演示,提供具有高性能交互性的新颖图形的优雅、简洁构造。
Bokeh 可用于在图形上绘制补丁。可以使用plotting
模块的patch()
方法在图上绘制补丁。
plotting.figure.patch()
Syntax : patch(parameters)
Parameters :
- x : x-coordinates of the patch
- y : y-coordinates of the patch
Returns : an object of class GlyphRenderer
示例 1:在此示例中,我们将使用默认值来绘制图形。
# importing the modules
from bokeh.plotting import figure, output_file, show
# file to save the model
output_file("gfg.html")
# instantiating the figure object
graph = figure(title = "Bokeh Patch Graph")
# the points to be plotted
x = [0, 1, 2, 3, 4, 5]
y = [5, 2, 8, 5, 0, 10]
# plotting the graph
graph.patch(x, y)
# displaying the model
show(graph)
输出 :
示例 2:在此示例中,我们将使用各种其他参数绘制补丁
# importing the modules
from bokeh.plotting import figure, output_file, show
# file to save the model
output_file("gfg.html")
# instantiating the figure object
graph = figure(title = "Bokeh Patch Graph")
# name of the x-axis
graph.xaxis.axis_label = "x-axis"
# name of the y-axis
graph.yaxis.axis_label = "y-axis"
# points to be plotted
x = [0, 0, 1, 1, 4, 2, 8, 4]
y = [2.5, 0.5, 0.5, 2.5, 5, 9, 1, 0]
# color value of the patch
color = "yellow"
# fill alpha value of the patch
fill_alpha = 0.5
# name of the legend
legend_label = "Sample Patch"
# plotting the graph
graph.patch(x, y,
color = color,
fill_alpha = fill_alpha,
legend_label = legend_label)
# displaying the model
show(graph)
