MATLAB: Change x-axis labels of plot

axisplot

Hi everbody,

I have a plot of 31 data points. However, instead of labeling the x-axis is (1:1:31), I want to set it to (-6:1:24). How can I do that?

solved much simpler by going

 figure,plot(-6:24,1:31)

because you're setting the x and y plot pairs.

%OPTION 1: Overwrite the XTickLabel property of the axes. (Simpler code but messy plot)
plot([1:10]*10^6, 1:10)
XTick = num2cell(get(gca, 'XTick'));
XTickLabel = cellfun(@(x) sprintf('%0.0f', x), XTick, 'unif', false);
set(gca, 'XTickLabel', XTickLabel, 'XTickLabelRotation', 90)
%OPTION 2: Determine what power was used, then adjust the x-axis name and XTickLabel. (Cleaner plot)
plot([1:10]*10^6, 1:10)
XTick = get(gca, 'XTick');
XTickLabel = get(gca, 'XTickLabel');
XTickLabelNum = str2double(XTickLabel{end});
Power = log10(XTick(end)/XTickLabelNum);
if Power ~= 0
  xlabel(sprintf('X TEXT (x 10^{%d})', Power))
else
  xlabel('X TEXT')
end
set(gca, 'XTickLabel', XTickLabel)
