我想制作一个 contour/surface 图，它显示单元格中的值，类似于 EFI 调整图
I want to make a contour/surface plot, which shows the values in the cells, similar to an EFI tuning map
我想在 MATLAB 中做这样的事情。这是一张地图，它有 x 和 y 轴以及 z 轴的值，z 值的大小用颜色表示。基本上是一个 countour 地图，它在屏幕上的矩阵中打印值
示例图：
修改 imagesc() 图
通过修改带有文本注释的 imagesc 图和创建网格的 line() 函数，这可能非常相似。需要完成一些轴属性（包括轴替换）才能正确配置绘图。不幸的是，这不是一种非常简洁的方法，但它可能会满足您的应用程序。
Engine_Load = [0.35 0.55 0.7 0.87 1 1.15 1.25 1.35 1.45 1.6 1.7 1.8 2 2.2 2.5];
Engine_Speed = (800:400:7600);
