Hi everyone,
I have plotted this for my mobile users distribution but i don't know how to change the axis on this figure now as i want them to correspond to distance, like instead of -1 to 1 they should read as 0 to 250 km on both the axes.

Aftab, you could simply
data_km = 125 * (data + 1);
where data would be your current one ranging from -1 to +1 and assuming a linear translation is justified. Make sure to scale both x- and y-data.

Set the 'XTick' and 'XTickLabel' manually
sphere
set(gca,'XTick',linspace(-1,1,6))
set(gca,'XTickLabel',cellstr(strcat(num2str((0:50:250).'),' km')))
