Matlab：颜色贴图颜色不反映图例

我能够用Matlab拍摄一张图像并在上面覆盖一张热图

我遇到的问题是，图例上的颜色编码与地图上显示的值不匹配

如果在1512x1080图像上运行下面的代码，您会注意到代码中使用的值与图例中指定的值不对应

例如，当考虑像素位置700400中的点时，人们期望显示红色，因为其对应值为0.3。然而，在生成的图像中，该点的颜色为蓝黄色

这是为什么？我如何纠正它

代码如下：

%Import an image***********************************************
%Ask a user to import the image they want 
%**************************************************************

%The commented out line will not show the file type when prompted to select
%an image
%[fn,pn] = uigetfile({'*.TIFF,*.jpg,*.JPG,*.jpeg,*.bmp','Image files'}, 'Select an image');

%This line will select any file type, want to restrict in future
[fn,pn] = uigetfile({'*.*','Image files'}, 'Select an image');
importedImage = imread(fullfile(pn,fn));


%Setting up the color map to use
ax = gca;
load('MyColormaps','mycmap');
colormap(ax,mycmap);


%Create size for heat map**************************************
%Setting the size for the map, see comments below
%**************************************************************

%What if I wanted an arbitrary dimension
%Or better yet, get the dimensions from the imported file
heatMap = zeros(1080,1512);


%Manually placing the heatmap values along a grid
%Want to set zones for this, maybe plot out in excel and use the cells to
%define the image size?
heatMap(84,328) = .38;
heatMap(132,385) = .42;
heatMap(86,418) = .40;
heatMap(405,340) = .60;
heatMap(263,515) = .35;
heatMap(480,627) = .40;
heatMap(673,800) = .28;
heatMap(598,892) = .38;
heatMap(540,1020) = .33;
heatMap(684,1145) = .38;
heatMap(275,912) = .44;
heatMap(185,798) = .54;
heatMap(700,400) = .3; %This is a testing point, not an actual value


%Generate the Map**********************************************
%Making the density and heat map
%**************************************************************
%Testing different filtering types
gaussiankernel = fspecial('gaussian', [350 350], 25);
%gaussiankernel = fspecial('average', [50 50]);

density = imfilter(heatMap, gaussiankernel, 'replicate');

%imshow(density, []);
oMask = heatmap_overlay(importedImage, density);
set(figure(1), 'Position', [0 0 1512 1080]);
imshow(oMask,[]);
colormap(mycmap);
colorbar;

我使用Matlab中的UI制作了自定义图例。
我不知道如何获取代码，它显示为64x3双精度
数组如下所示（对不起，我不知道如何在这里制作表）

我使用的函数是在GitHub上找到的。 链接如下：

您的代码使用了未包含的自定义颜色贴图和功能（热图覆盖），因此很难为您提供帮助。使用默认的颜色贴图，密度图像看起来很好，所以我怀疑您的自定义颜色贴图或函数中有什么东西。此外，此示例不需要代码的文件导入部分。抱歉，感谢提醒。我现在已经上传了自定义颜色贴图。我不知道它是作为数组编写的。我还链接到了所使用的函数。我注意到“colorfun='jet'；”和jet的状态，并且是一个颜色映射选项。这可能是问题所在吗？我注意到函数heatmap_overlay（）只能调用三种颜色样式，而且是可选的。如何从函数中省略颜色，并让Matlab识别我在图例中设置的颜色？
