Pixel shifts from its actual position in Matlab geospatial plots?

I am plotting a spatial map in MATLAB, where I have LAT-LON info for corresponding fill values.

Though the grid lines follows the meridian and parallels drawn in MATLAB plot domain, the fill values are shifting from their bounding grids.

How to resolve this error?

This is what I am trying

i=1;

data_plot=reshape(data(i,:),10,9);

axesm('MapProjection','mercator',...
    'MapLatLimit', [19.5,24],...
    'MapLonLimit', [80,85],...
    'AngleUnits', 'degrees',...
    'MLineLocation',0.5,'MLabelParallel','south',...
    'PLineLocation',0.5,'PLabelMeridian','west',...
    'MeridianLabel','on',...
    'ParallelLabel','on',...
    'FontSize', 8,...
    'Grid', 'on',...
    'GLineWidth', 0.15,...
    'Frame', 'on',...
    'FLineWidth', 0.2,...
    'FFaceColor', [0.9 0.9 0.9]);

geoshow(lat,lon,data_plot, 'DisplayType', 'texture'); % save object
colormap(brewermap([],'Spectral')); % Use brewermap library for colorbar

shape=shaperead(shapefile,  'UseGeoCoords', true);
geoshow(shape, 'LineWidth', 0.1, 'FaceColor','none')

set(gca,'Visible','off')

Here is the data that I have used

I am using MATLAB R2016a
