在MATLAB绘图中,色彩的选择对于数据的可视化效果至关重要。让我们来探索7种常用的、能够提升图表吸引力的配色方案:1. 黑色(-k)开始时,我们常常使用纯黑色('-k')来强调线条的清晰,如这行代码:plot([1 10],[1 1],'-k','linewidth',2); 线宽设置为2,确保信息传递的力度。2. 蓝色('-b ...

另一种方法是将两个图表绘制在同一张图中,以实现更加紧凑的布局。可以使用subplot(1,2,1)创建一个1行2列的网格布局,并在第一个子图中绘制第一个图表,代码如下:subplot(1,2,1), plot(tmpx,freqt,'linewidth',2)然后使用subplot(1,2,2)定位到第二个子图,并绘制第二个图表,代码如下:s ...
