MATLAB 中 legend 可以翻译为图例,下面逐一用例子来说明 legend 的用法,并辅以必要的说明。 我只挑选几种使用的来说明。 legend 在作图命令中(plot)给出图例标签; Plot two lines. Specify the legend labels during the plotting commands by setting the DisplayName property to the desired text. Then, add ...
This syntax allows the legend to show only the items listed in the subset. For example, if three curves are drawn, only two of them can be shown in the legend. Note that using this method requires assigning a plot to a specific variable. ...
