我使用plot()在MATLAB中绘制一条轨迹。我想添加带有不同刻度线（线性缩放）的右y轴。这可能吗？

plot(rand(1, 10)); % Plot some random data ylabel(gca, 'scale 1'); % Add a label to the left y axis set(gca, 'Box', 'off'); % Turn off the box surrounding the whole axes axesPosition = get(gca, 'Position'); % Get the current axes position hNewAxes = axes('Position', axesPosition, ... % Place a new axes on top... 'Color', 'none', ... % ... with no background color 'YLim', [0 10], ... % ... and a different scale 'YAxisLocation', 'right', ... % ... located on the right 'XTick', [], ... % ... with no x tick marks 'Box', 'off'); % ... and no surrounding box ylabel(hNewAxes, 'scale 2'); % Add a label to the right y axis 这是您应该得到的：
