Question

例如我有值

starTime1 = 1.5
starTime2 = 3
starTime3 = 2.3

我有三个水平的酒吧，例如名字： BAR1 BAR2 BAR3

我有“x”比例= 24小时（范围0.25）

那么如何从值“startTime”绘制条形图，而不是从零开始。

有我的代码。变量“排名”是吧的结束时间。

Answer 1

您可以使用left关键字barh（或垂直条的bottom关键字）来更改条形的起始位置。但是，您必须从条形长度中减去相同的数量。

示例：

pylab.barh( [1,2,3], [10,20,30], left=20 )

从起始时间绘制条形图而不是零
