如何将密度图旋转任意角度,再加上Frame边框

Question

我想要画这样的一个图

我的数据已经计算好了https://mmaqa.com/qa/?qa=blob&qa_blobid=5017679672254126564

我自己试了一下,只能做到这样

SetDirectory[NotebookDirectory[]];
da = Import["wavenorm-v2.dat"];
{x, y, z} = Transpose[da];
pos = Transpose[{x, y}];
p1 = Graphics[{Table[{Blend[{Darker@Blue, White, Red}, z[[i]]*20], 
      PointSize[0.05], EdgeForm[{Thick, Black}], Point[pos[[i]]]}, {i,
       1, Length[pos]}]}];
p1 = Rotate[p1, 45 Degree]

Answer 1

da = Import["D:/wavenorm-v2.dat"];
{x, y, z} = 
 Transpose[Select[da, Length[#] == 3 &]]; (* da中有空行，需要过滤一下 *)
pos = Transpose[{x, y}];
p1 = Graphics[{Table[{Blend[{Darker@Blue, White, Red}, z[[i]]*20], 
      PointSize[0.03], EdgeForm[{Thick, Black}], Point[pos[[i]]]}, {i,
       1, Length[pos]}]}];
p1 = Rotate[p1, 45 Degree]

感谢, 但是我还想再加上这个颜色的BarLegned,自己没搞定,请教一下怎么加上它,谢谢

试试这样呢

da = Import["D:/wavenorm-v2.dat"];
{x, y, z} = Transpose[Select[da, Length[#] == 3 &]];(*da中有空行，需要过滤一下*)


pos = Transpose[{x, y}];

zColor = Sort[Table[z[[i]]*20, {i, 1, Length[pos]}]];
bl = BarLegend[{Blend[{Darker@Blue, White, Red}, #*20] & /@ zColor,
    MinMax[zColor]}];

p1 = Graphics[{Table[{Blend[{Darker@Blue, White, Red}, z[[i]]*20],
     PointSize[0.02], EdgeForm[{Thick, Black}],
     Point[RotationMatrix[45 Degree] . pos[[i]]]}, {i, 1,
     Length[pos]}],
   Inset[bl, {25, 15}, Center, 5]}]

解决了，我在美化修改一下，谢谢
