It's Possible chage the X-axis in order to hide the blank space?

I cant find how chage the X-axis so that reduce the blank space between these points (space between blue bars in the picture) I attach my code andmy .txt file.

I tried whit other optios but the results not is what I want. The important for this question in the code starting from figure(1)

close all;
clearvars;
clc;
%% import data for permeability
IFT = importdata('IFT.txt');

%% calll the measurement of IFT
time   = IFT(:,1);  %% Call step time
IFTHSW = IFT(:,3); %%Call IFT measurement
IFTLSW1 = IFT(:,4); %%Call IFT measurement
IFTLSW2 = IFT(:,5); %%Call IFT measurement
IFTLSW4 = IFT(:,7); %%Call IFT measurement

%% Find mean and standar desviation

meanIFTHSW = mean (IFT(:,3));
meanIFTLSW1 = mean (IFT(:,4));
meanIFTLSW2 = mean (IFT(:,5)); 
meanIFTLSW4 = mean (IFT(:,7));

stdIFTHSW  = std   (IFT(:,3));
stdIFTLSW1 = std  (IFT(:,4));
stdIFTLSW2 = std  (IFT(:,5)) ;
stdIFTLSW4 = std  (IFT(:,7));

IFT = [meanIFTHSW meanIFTLSW1 meanIFTLSW2 meanIFTLSW4]'
salmuera = [30000 500 2000 500]'


figure(1)
E = plot(salmuera,IFT, 'o', 'MarkerSize', 8,'MarkerEdgeColor' , [.49 1 .63], 'MarkerFaceColor' , 'k')
%xticks('auto')
%smart_clean('NoWhiteSpace');
xlim([0 30500]) 
%ylim([0 25])

There are some FileExchange functions that may serve your needs. See this post.

If you want to do this yourself, see the discussion in this post.
