Python Bokeh–在图形上绘制线段
Bokeh 是一个 Python 交互式数据可视化工具。它使用 HTML 和 JavaScript 来渲染它的图。它以现代网络浏览器为呈现目标,提供优雅、简洁的新颖图形结构和高性能交互性。
Bokeh 可用于在图形上绘制线段。可以使用plotting
模块的segment()
方法在图形上绘制线段。
绘图.图.段()
语法:段(参数)
参数:
- x0 : 线段起点的 x 坐标
- y0 : 线段起点的 y 坐标
- x1 : 线段端点的 x 坐标
- y1 : 线段终点的 y 坐标
返回:类的一个对象

示例 1 : 在本例中,我们将使用默认值绘制图表。
# 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 Segment Graph")
# the points to be plotted
x0 = 0
y0 = 0
x1 = 10
y1 = 10
# plotting the graph
graph.segment(x0, y0,
x1, y1)
# 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多条线段
# 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 Segment 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
x0 = [0, 0, 5]
y0 = [0, 5, 0]
x1 = [10, 10, 5]
y1 = [10, 5, 10]
# color of the lines
line_color = ["yellow", "red", "purple"]
# value of line dash
line_dash = "dotted"
# thickness of the lines
line_width = [15, 10, 20]
# plotting the graph
graph.segment(x0, y0,
x1, y1,
line_color = line_color,
line_dash = line_dash,
line_width = line_width)
# displaying the model
show(graph)
输出:
