colormap总是蓝色的阴影

Hello, I am having a problem with the colormap... I'd like to have a picture like the one on the top... I ran the code and then I re-run in another PC (with a different version of Matlab --> r2020 vs r2021b)... And what I obtained with the SAME code is the graph on the bottom. Do you have a solution? Because I red that it happens sometimes, but I couldn't find a solution. Thank you in advance.

您没有指定结肠长度。如果您不这样做，
结肠()
will create a map equal to the length of the current map. In earlier versions, the default length is 64, while in newer versions, it's 256. That said, if you had previously ran a script that set
菌落（Parula（17））
, calling
结肠(jet)
will create a map of length 17 instead of 64 or 256. In other words, if you don't explicitly specify the map length, you have no control over how long the map is.
地图=喷气(元素个数(cmap_dB));% just get the map; don't need colormap()
对于它的价值，您也可以使用PolarScatter（）来完成此操作
angle=[5.58,3.49,4.19,0.35,2.79,3.49,3.14,3.49,3.14,5.58,0.35,0.35,3.14,3.84,2.79,3.84,3.14];
d=[15.83,8.46,11.69,10.18,11.05,10.79,6.72,10.59,9.89,10.23,10.33,9.32,10.02,8.14,10.88,8.07,6.61];
P=[-129.89,-129.76,-128.61,-128.32,-127.83,-127.75,-127.64,-127.40,-127.32,-127.22,-126.49,-125.19,-123.50,-120.44,-115.72,-111.30,-101.68];
Pmax=min(P);
pmin = max（p）;
delta_c = (Pmax - Pmin) / 63;
cmap_dB = Pmin + (0:63) * delta_c;
地图=喷气(元素个数(cmap_dB));% specify map length
[〜，idx] = min（abs（p -cmap_db。'））;
h = polarscatter(angle, d, 75, map(idx,:),'filled');
