I have made a candlestick currency chart on python using `matplotlib.finance`. Everything is working but I would like to add lines and shapes on the actual chart. When I was using normal type of chart in matplotlib. I would be doing:

```
plt.plot([xmin, xmax], [0.0005,0.0005], linewidth=3, color='purple')

```

To draw a horizontal line from `xmin` to `xmax` (to be defined) at the 0.0005 price level.But since I am using the method `candlestick2_ohlc` I don't really know how to proceed...

This is what I have:[![enter image description here](https://i.stack.imgur.com/Hs09U.png)](https://i.stack.imgur.com/Hs09U.png)

This is what I am looking to get:[![enter image description here](https://i.stack.imgur.com/KXRBD.png)](https://i.stack.imgur.com/KXRBD.png)

Also is it possible to draw and fill triangles?
