Hide x-axis tick labels where x values are under certain conditions. Code:

Output from "x_ticks_labels = [str(m) if 1400 < t or t < 1500 else '' for m, t in zip(x, df['tax'])]":

Output from "x_ticks_labels = [str(m) if 140 < t and t < 150 else '' for m, t in zip(x, df['tax'])]":

In the case above, this expression sets the x-axis tick labels to the mileage values if the corresponding tax values are between 140 and 150. Otherwise, it sets the tick label to an empty string, effectively hiding it.

Output from "x_ticks_labels = [str(m) if 140 > t or t > 150 else '' for m, t in zip(x, df['tax'])]": 

Others:

• # Show x-axis tick labels only when tax values are greater than 150 

  x_ticks_labels = [str(m) if t > 150 else '' for m, t in zip(x, df['tax'])] 

===========================================

Show only one x-axis tick label after hiding three x-axis tick labels and if t > 150. Code: 

Output:
