I need to make a candlestick chart (something like this) using some stock data. For this I want to use the function matplotlib.finance.candlestick(). To this function I need to supply quotes and "an Axes instance to plot to". I created some sample quotes as follows:
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)] I now also need an Axes instance though, at which I am a bit lost. I created plots before using matplotlib.pyplot. I think I now need to do something with matplotlib.axes though, but I am unsure what exactly.
Could anybody help me out a little bit here? All tips are welcome!

The gca() function in pyplot module of matplotlib library is used to get the current Axes instance on the current figure matching the given keyword args, or create one.
axis() method allows you to set the x and y limits with a single call, by passing a list which specifies [xmin, xmax, ymin, ymax] : In [11]: plt. plot(x, np.
Use the gca ("get current axes") helper function:
ax = plt.gca() Example:
import matplotlib.pyplot as plt import matplotlib.finance quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)] ax = plt.gca() h = matplotlib.finance.candlestick(ax, quotes) plt.show()
