I am plotting a graph from csv file.
however in the output graph x is ranging between 1 to 6 and it is represented like `[1,2,3,4,5,6]`.
What changes i should made in code so that it will be represented in `[1,1.5,2,2.5,3,3.5,4,4.5,5,5.5,6]`.

```
import pandas as pd
import matplotlib.pyplot as px
df = pd.read_csv('/home/madhu/Desktop/plotDatap4.csv')
df.plot(kind='line',x='Access Distance(in log)',y='Cummulative probability')
px.show()

```
