How to grid ride of constant values of data in plotting?

Hi,

I have attached my data and plotting a figure by using following code:

T= ones(size(Vp_time,1),1)*time';
X_dir=squeeze(X(:,1,1))*ones(1,size(Vp_time,2)); 
figure;clf;surf(X_dir,T,Vp_time);view([0,90]);shading interp;grid on;set(gca,'YDir','reverse');colorbar
set(gca,'FontName','Times New Roman', 'fontsize', 20,'FontWeight','bold', 'linewidth', 3)
%ylim([1050 1800])
%xlim([5.55e5 5.675e5])
ylabel('Time (s)');
xlabel('X (m)');
colormap(jet) 

when I run my code figure (below) appears: I want remove light below color data (above, below and from left side). How can I adjust a code such that it does not conside the constant values (of blue color):

I want to plot figure ike this:

You have not attched your data. Attach your data.

@KSSV sorry, it is attached now.

You can modify z-axis data so that constant values are reassigned to nan, thus surface plot function does not plot these values.

You can add this line before plotting the figure-

Vp_time(Vp_time==2450)=nan;

This will result in following figure-
