组装许多曲线的图例 [英] Assemble Legend for Many Curves

问题描述

我需要为索引曲线组装一个Matlab/Octave图例，并且发现以下示例似乎运行良好:

I need to assemble a Matlab/Octave legend for indexed curves, and I found the following example which seems to work well:

legend(strcat("curve ", num2str(1:2)))

将标签曲线1"和曲线2"与给定的两条曲线相关联.但是，如果我需要添加其他非索引类型的曲线，则上述方法似乎不再起作用.

Associates the labels "curve 1" and "curve 2" with the two curves given. However, if I need to add a different, non-indexed type of curve, the method above seems not to work anymore.

legend(strcat("curve ", num2str(1:2)),"another curve")

在第二个示例中，第一条曲线具有图例["curve 1";曲线2"]，第二条曲线获得图例的另一条曲线"，而最后一条曲线没有图例.我认为这与图例解释输入的方式有关，但我无法解决它.

In the second example the first curve has for legend ["curve 1"; "curve 2"], and the second curve gets "another curve" for legend, while the last curve gets no legend. I think it has to do with the way legend interprets input, and I'm not able to get around it.

推荐答案

尝试预先将图例组装为单元格数组，然后将其用作图例输入.

Try assembling the legend as a cell array beforehand, and then using that as the legend input.

legendCell = cell.empty
for i = 1:2
   legendCell{i} = ['curve' num2str(i)];
end
legendCell{end+1} = 'another curve';
legend(legendCell);
