用每个数据点绘制图

Question

# 3 = rest cycle 
# 1 = discharge

rest_start = np.zeros(len(mode))
past_mode = float(3)

for i in range(len(mode)):
    if mode[i] == float(3):
        if mode[i] != past_mode:
            rest_start[i] = 1
            past_mode = mode[i]

for i in range(len(rest_start)):
    if rest_start[i] == 1:
        ax0.plot(t[i]/3600,V[i],'ro')

我需要在情节上绘制所有低点。现在，我在充电周期上只有点，但放电时点很高，应该低。
