For loop for plotting multiple plots in matplotlib

Question

for symbol in symbols:
    data = con.get_candles(symbol, period='D1', start = start, end = end)
    data1 = con.get_candles('USOil', period='D1', start = start1, end = end)
    ax = data['bidclose'].plot()
    data1['bidclose'].plot(ax=ax)

I have used the code above in the hope that it will plot symbol and usoil in 1 chart and then produce another chart with the next in line symbol and usoil until all the symbol list has been exhaused. However evertything is getting plotted in the same chart.

How can i use the for-loop where 1 symbol in the list of symbols and usoil get plotted? Thus there will be n numbers of plots where n is the number of symbol in symbols.

I think you could create a new figure everytime through the loop. — user1558604

@user1558604 I thought so too but everything is getting plotted in the same chart! I am actually trying to recreate an errorValueError: cannot reindex from a duplicate axis I hoped it would show up but for some reason it did not! — Slartibartfast

This is why I like the object-oriented way, it takes a bit longer to write but you have better control (/ comprehension) over what ax and figure are shown. It allows to manually open/save/close figures. — Guimoute

Just put plt.show() in your routine:

for symbol in symbols:
    data = con.get_candles(symbol, period='D1', start = start, end = end)
    data1 = con.get_candles('USOil', period='D1', start = start1, end = end)
    ax = data['bidclose'].plot()
    data1['bidclose'].plot(ax=ax)
    plt.show()
