How can I multiply axis values by 1000 without changing the data?

With the script shown below,

figure()
for CH = 2:33
    Y = (avg(:,CH) - avgBG(CH) + SP);
    hold on
    plot(avg(:,1), Y)
    xlim([0 0.3]); xlabel('Time (s)');
    ylim([-0.034 0.034]); ylabel('Position (m)');
    SP = SP + 2/1000;      
end

I've created this figure:

I want to change the Y-axis values on the figure to be multiplied by 1000.

I tried Yticks, but I don't think I've implemented it correctly. Any suggestions?

You can either multiply the y-values with 1000, or use the YTickLabels:

ticks=get(gca,'YTicks');%retrieve current ticks
ticks=ticks*1000;%multiply
ticks=cellfun(@num2str,tick,'UniformOutput',false);%convert to cellstr
set(gca,'YTickLabels',ticks)%set new tick labels
