I’m trying to make a simple line plot with matplotlib.pyplot but i don’t get lines between datapoints.
I have a pandas DataFrame with a DateTime index and I want a subplot for each weekday. Everything works fine except when I have data in muliple columns.

I have a dataframe that looks like this:
Floor IDR 1 IDR 2 1 1 15 36 2 2 6 12 3 3 7 78 4 4 9 23

I am trying to create subplots in Matplotlib where the first plot is a stacked bar plot and the second plot is a line plot. Both plots should share the same datetime index for the x-axis. However, I am facing an issue where the second plot does not show any data.

I am new to matplotlib and I was watching this codes:

I found these answers But, noone works to my case, which is:

Basically, what I’m trying to do is detect the days inside a .CSV file, and once these days have been extracted, display hour by hour OR from a specific hour to another hour.

Bassically what im trying to do is detect the days inside a .CSV file, and once this days have been extracted, display hour by hour OR from a specific hour to other hour.

Suppose, I have 9 plots I want to make from a dataframe with 9 columns. So I create 9 axes with fig, axes = plt.subplots(3, 3). Now, I iterate over my 9 columns with for name, data_col in data.items() and do my plotting (for example data_col.value_counts().plot.barh()).

Plot does not show up in windows after adding new features into an axes variable, but only gives an output [<matplotlib.lines.Line2D at 0x273b82d3f50>].

I have a dataframe which I want to plot with matplotlib, but the index column is the time and I cannot plot it.
