Individual plots worked but once added subplot, nothing shows up

Question

I am trying to put together four subplots that are made using pandas.plot() method. When plotting separately, they show up fine as below:

But once I started using subplot, it became this:

I know there might be something to do with either naming the plot objects or using pyplot instead of the pandas .plot method, but couldn't figure out after tried different things. Any hint is appreciated.

I always do plotting in a much more object oriented fashion to make sure that I have a handle on my subplots — Keith, Nov 15 '17 at 03:55
Right. Can you provide a solution or some specific steps? Thank you @Keith! — George Liu, Nov 15 '17 at 04:20
Would you consider swapping out your screenshots for actual code constituting an [`MCVE`](https://stackoverflow.com/help/mcve)? — andrew_reece, Nov 15 '17 at 04:45
Look at the syntax of the second plot here https://matplotlib.org/1.2.1/examples/pylab_examples/errorbar_demo.html — Keith, Nov 15 '17 at 06:19
instead of `dem_GDP_HDI_urb.plot()` you should use `plt.plot()` — Shihe Zhang, Nov 15 '17 at 06:20

Use the ax argument.

df = pd.DataFrame({"foo":[4,5,6], "bar":[1,4,2]})

f, (ax1, ax2) = plt.subplots(2, 1, figsize=(4,3))

df.foo.plot(ax=ax1)
df.bar.plot(ax=ax2)

You can try also in this way for example:

fig = plt.figure()
ax = fig.add_subplot(221)
plt.plot(x,y)

ax = fig.add_subplot(222)
plt.plot(x,z)
...

plt.show()
