Bokeh - Area Plots

面积图是两个共享公共索引的序列之间的填充区域。Bokeh 的图形类有以下两种方法：

Area plots are filled regions between two series that share a common index. Bokeh’s Figure class has two methods as follows −

varea()

varea() 方法的输出是一个垂直有向区域，它有一个 x 坐标数组和两个 y 坐标数组 (y1 和 y2)，它们将在之间填写。

Output of the varea() method is a vertical directed area that has one x coordinate array, and two y coordinate arrays, y1 and y2, which will be filled between.

1

x

The x-coordinates for the points of the area.

2

y1

The y-coordinates for the points of one side of the area.

3

y2

The y-coordinates for the points of the other side of the area.

Example

from bokeh.plotting import figure, output_file, show
fig = figure()
x = [1, 2, 3, 4, 5]
y1 = [2, 6, 4, 3, 5]
y2 = [1, 4, 2, 2, 3]
fig.varea(x = x,y1 = y1,y2 = y2)
output_file('area.html')
show(fig)

Output

varea

harea()

另一方面，harea() 方法需要 x1、x2 和 y 参数。

The harea() method on the other hand needs x1, x2 and y parameters.

1

x1

The x-coordinates for the points of one side of the area.

2

x2

The x-coordinates for the points of the other side of the area.

3

y

The y-coordinates for the points of the area.

Example

from bokeh.plotting import figure, output_file, show
fig = figure()
y = [1, 2, 3, 4, 5]
x1 = [2, 6, 4, 3, 5]
x2 = [1, 4, 2, 2, 3]
fig.harea(x1 = x1,x2 = x2,y = y)
output_file('area.html')
show(fig)

Output

harea
