我有以下 MATLAB 代码，它直观地显示了 DCO-OFDM 和 m-CAP 在覆盖范围与 QAM 阶数方面的差异。条形表示各种配置下的覆盖范围，其中一些条形段为红色和蓝色，表示特定效果（例如 LOS+NLOS）。

当前图例已经描述了配置（例如，m-CAP 和 DCO-OFDM 的角度）。但是，我想为红色和蓝色条段添加两个额外的图例条目来解释它们的重要性，如附图所示。

目标是在现有图例下添加两个额外的图例，代表：

  • 红色条：LOS+NLOS 对 m-CAP 的影响。
  • 蓝色条：LOS+NLOS 对 DCO-OFDM 的影响。

以下图像清楚地说明了所需的图例布局：

在此处输入图片描述

我可以得到帮助来实现这一点吗？具体来说：

  • 如何在不破坏现有图例的情况下为这些条形颜色添加红色和蓝色图例？
  • 有没有更有效的方法来实现这个结果？提前感谢您的帮助！

下面是我用于创建条形图的 MATLAB 代码示例：

我正在从事一个 MATLAB 项目，其中有两组数据：

1-“无反射”：表示基线覆盖面积值。2-“有反射”：表示具有附加反射效果的覆盖面积值。

我将这两个数据集绘制为分组条形图，并希望突出显示反射造成的差异。具体来说，我需要在“无反射”条形图上方以不同颜色突出显示与差异（反射效果）相对应的每个条形图部分。

在此处输入图片描述

示例： 例如，如果：

  • 第一个条（QAM = 16）的“无反射”值为 120 平方米。
  • 同一酒吧的“含反射”值为 160 平方米。

我想要：

1- 绘制一个代表 120 平方米（“无反射”的基准值）的条形图。

2- 用红色突出显示蓝色条顶部的差异（160 - 120 = 40 平方米）（突出显示反射效果）。

我想将此应用到右侧图片上的所有条形图上。有什么可以帮忙的吗？

这是我的代码：

close all;
clear variables;
clc;

QAM = [16, 32, 64, 128, 256, 512, 1024];
