Using fit options to fit 3-D data using ft='linearinterp'. I only want to plot the fit and not the data used to make the fit. How do I do this?

I want to only plot the surface without the little blue dots (which is actually my original data). Is there an option to do this?

function [fitresult, gof] = createFit(x, y, z ,S)
%CREATEFIT(X,Y,Z)
%  Create a fit.
%
%  Data for 'untitled fit 1' fit:
%      X Input : x
%      Y Input : y
%      Z Output: z
%  Output:
%      fitresult : a fit object representing the fit.
%      gof : structure with goodness-of fit info.
%
%  See also FIT, CFIT, SFIT.

%% Fit: 'untitled fit 1'.
[xData, yData, zData] = prepareSurfaceData( x, y, z );
% Set up fittype and options.
ft = 'linearinterp';
% Fit model to data.
[fitresult, gof] = fit( [xData, yData], zData, ft, 'Normalize', 'on' );
% Plot fit with data.
%fig1 = figure(1);
%set(fig1,'rend','painters','pos',[10 10 1200 1200])
fig = figure('rend','painters','pos',[10 10 1200 1200])
h = plot( fitresult, [xData, yData], zData );
%legend( h, 'untitled fit 1', 'z vs. x, y', 'Location', 'NorthEast' );
%title(colorbar, 'Frequency')
