Create stacked bar of multipe data frame

I wrote for my thesis an algorithm to archive and restore graphs. Now I am supposed to graphically compare the insertion/restore times (best case as showing a bar for insert and one for restore next to each other) - and I fail.

There are two pandas data frames:

ipdb> df_restore
    Records  Iteration  Restore Time

and

ipdb> df_insert
      Records  Iteration  Insertion Time
0        2500          2       20.194639

3        2500          5       21.892382
4        2500          6       29.116028
...       ...        ...             ...

1131   100000         19        0.080163

[1132 rows x 3 columns]

Which might be displayed better as:

ipdb> df_insert.groupby("Records").sum("Insertion Time")
         Insertion Time
Records                
50         29.008606
123        30.848057
125        31.523406
250        60.609737
500        119.645833
750        164.781358
1000       234.136944
2500       561.528021
5000       1142.696352
12500     -3.389009 # ??
15000      39491.624527
25000     -94.609073  #Has fewer values
50000     -51.900527  # Errors, just skip it
100000    -57.855016 # Same

As you can see there are some errors or wrong numbers, so apparently during the test-runs something happened and i need to re-evaluate the disputed checks. Can be also because I might have used the wrong function, but this aggregate should just show how the rest of the data frame looks rather than being precise.

I am able to do the restore-time-stacks already, currently I am showing them as single bars. That was not so much of an issue:

 px.bar(df,
                      y='Restore Time',
                      hover_data=df_single,
                      color='Restore Time',
                      x= 'Records', 
                      height: 400, 
                      width: 400)

with the following data:

    Records  Iteration  Restore Time
12    12500          1   1983.945377
8     12500         75    451.966560
7     12500         98     10.030826
11    12500         10   1842.296471
10    12500         25   1522.143016
9     12500         50    957.616956

and gives something I am satisfied with:
Selection_406

I managed to plot the inserts next to each other similarly (note, the y-axis is logarithmic)

However, I would like to display this Restore-Bar next to the equivalent Insertation-Bar.
I considered using facet_col but I’m not really getting anything meaningful. Also I can’t find anything to add two data frames to the set.

I considered merging the two data frames to one, but I doubt that would be meaningful. Both have Records, which would be the foreign-key or the category of the bar. However the β€œIteration”-value is not compatible and the new data frame would be somewhat nonsensical.

Is there a plot that would work for this?
