### What changes were proposed in this pull request?
This PR proposes to port the fix https://github.com/databricks/koalas/pull/2172.
```python
ks.DataFrame({'a': [1, 2, 3], 'b':["a", "b", "c"], 'c': [4, 5, 6]}).plot(kind='hist', x='a', y='c', bins=200)
```
**Before:**
```
pyspark.sql.utils.AnalysisException: cannot resolve 'least(min(a), min(b), min(c))' due to data type mismatch: The expressions should all have the same type, got LEAST(bigint, string, bigint).;
'Aggregate [unresolvedalias(least(min(a#1L), min(b#2), min(c#3L)), Some(org.apache.spark.sql.Column$$Lambda$1556/0x0000000800d9484042fb0cc1)), unresolvedalias(greatest(max(a#1L), max(b#2), max(c#3L)), Some(org.apache.spark.sql.Column$$Lambda$1556/0x0000000800d9484042fb0cc1))]

+- LogicalRDD [__index_level_0__#0L, a#1L, b#2, c#3L], false
```
**After:**
```python
Figure({
'data': [{'hovertemplate': 'variable=a<br>value=%{text}<br>count=%{y}',
'name': 'a',
...
```
### Why are the changes needed?
To match the behaviour with panadas' and allow users to set `x` and `y` in the DataFrame with non-numeric columns.
### Does this PR introduce _any_ user-facing change?
No to end users since the changes is not released yet. Yes to dev as described before.
### How was this patch tested?
Manually tested, added a test and tested in notebooks:
