Hello,
I have a question about a code. Well, I have created a contour map with contourf command.
I would like to convert the linear scale bar to logaritmic scale bar.
I ve used these commands:
[loni, lati] = meshgrid(...
linspace(min(lon),max(lon)),...
linspace(min(lat),max(lat)));
Tempi = griddata(lon,lat,Temp, loni,lati);
contourf(loni,lati,Tempi)
could anyone help me?

You can set the scale to log like so:
set(gca,'xscale','log','yscale','log');

Could anyone help me?
