### Description
The first tick label on a categorical x-axis is not correctly placed horizontally when tick labels are rotated at an angle (not 0 or 90 degrees). It is much closer to the second tick label than it should be. I noticed that while working with a larger set of labels. This can also be easily seen with a smaller set of labels by making the plot very narrow. I have tested `bar`, `area`, `line`, and `scatter`. They all have that issue.

### Example
```python
import hvplot.pandas
import pandas as pd

df = pd.DataFrame([["Steven Spielberg", 5],
["Alfred Hitchcock", 4],
["Stanley Kubrick", 4],
["Billy Wilder", 4],
["John Huston", 3]],
columns=['Director', 'Frequency'])

df.hvplot.bar(rot=45, x='Director', y='Frequency', width=150)
```
