How to suppress the "1" from x-axis?

I want a figure between fitness vs PID gains. I get it but "1" is displayed on x-axis. How to suppress this "1" from x-axis? The required Mat file is hereby attached. The code is given below:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% By Star Strider on 19-10-2020-I used this one
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
clear all
close all
clc

load PIDGains  
fitness2sn0=one; 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Descending Order
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
fitness2sn0=sort(fitness2sn0,'descend');

figure
h1=boxplot([fitness2sn0].');      
set(h1,{'linew'},{2}) 
grid
Ax = gca;
Ax.XLabel.String = '\bf PID Gains';
Ax.YLabel.String = '\bf fitness';
Ax.YScale = 'log';
Ax.YLim = [1E-7 1e-5]; 
title('\bf Fitness for Kp, Ki and Kd')
set(gca,'linew',2)
