I'm having troubles trying to make a bar plot from a pandas dataframe, which should be easy but I can't make it work.
I have a dataframe that looks like that:

|  | Data A | Data B | Data C |
| --- | --- | --- | --- |
| timestamp |  |  |  |
| 06:54:00 | 0.1 | 0.2 | 0.3 |

But instead of 3 columns with Data, I have 99.
The point is that I am trying to do a bar plot representing in the x axis the different Data and in the y axis the values.

I tried with:

```
p = data.hvplot.bar(x = 'Data', y = 'Units', rot = 90)

```

And

```
p = data.plot(kind='bar', title="Data", figsize=(15, 10), legend=True, fontsize=12)

```

But none of them are working, and I think that the problem comes from the format of my dataframe, because of the column 'timestamp'.
However, I haven't manage to delete it, I tried:

```
data = data.droplevel('timestamp')

```

And:

```
data = data.drop(['timestamp'], axis=1)

```

But none of them are working. Could someone please give me a hand with that?
