Highlighting last data point in pandas plot

Question

I have number of graphs similar to this:

import pandas as pd
dates = pd.date_range('2012-01-01','2013-02-22')
y = np.random.randn(len(dates))/365
Y = pd.Series(y, index=dates)
Y.plot()

The graph is great for showing the shape of the data, but I would like the latest value to stand out as well. I would like to highlight the last data point with a marker 'x' and with a different color. Any idea how I can do this?

Have added Dan Allan's suggestion. Works but I need something a bit more visible. As seen below the x is hardly visible. Any ideas?

Have added return of final answer to complete this. Changed the x to a D for a diamond for better visibility and increased the size of the marker.

Y.tail(1).plot(style='rD',markersize=10)

Answer 1

将此行添加到您的示例中，将最后一个数据点绘制为红色X.

Y.tail(1).plot(style='rx')
