要处理不同的缩放比例,您可以手动乘以left
要缩放的值,然后修改该侧的刻度线。
% Automatically determine the scaling factor using the data itself
scale = max(right) / max(left);
% Create the left bar by scaling the magnitude
barh(1:numel(left), -left * scale, 'r');
hold on
barh(1:numel(right), right, 'b')
% Now alter the ticks.
xticks = get(gca, 'xtick')
% Get the current labels
labels = get(gca, 'xtickLabel');
if ischar(labels);
labels = cellstr(labels);
end
% Figure out which ones we need to change
toscale = xticks < 0;
% Replace the text for the ones < 0
labels(toscale) = arrayfun(@(x)sprintf('%0.2f', x), ...
abs(xticks(toscale) / scale), 'uniformoutput', false);
% Update the tick locations and the labels
set(gca, 'xtick', xticks, 'xticklabel', labels)
% Now add a different label for each side of the x axis
xmax = max(get(gca, 'xlim'));
label(1) = text(xmax / 2, 0, 'Right Label');
label(2) = text(-xmax/ 2, 0, 'Left Label');
set(label, 'HorizontalAlignment', 'center', 'FontWeight', 'bold', 'FontSize', 15)
