Axes not appearing when I save plot in a folder

When I am plotting a figure, axes are showing in the plot editor

But when I am directly saving the plot as .png in a folder, axes are not showing up.

I want all four axes, so my figure looks complete.

hh=pcolor(lon,lat,ghs)

set(hh,'EdgeColor', 'none');
 box on
Color=[1,1,1;
    1,0.8,0;
    1,0,0;
    0.4,0,0];
colormap(Color);
set(gca,'FontSize',20)

caxis([0 3])
cd ('C:\Users\soura\Documents\synop\figures\ch2_2\');%When I am saving it here, the axes are not apearing. but it is applearing in the plot editor

saveas (gcf,'a.tiff');
