Plot Y axis with 1x unit

I have a data include 2 columns in excel. I want to plot the first column against the second column with plot command:

plot(data(:,1), data(:,2));

But the plot devides the Y axis in every 2 units (2x), while I need to show 1x in Y axis. How can I specify the unit for Y axis ?
