在matlab中绘制数据并更改轴值

Question

我正在尝试对一个由81个单元格进行343的excel文件的三维图形，第一列需要是X，第一行需要是Y，剩下的矩阵需要是Z.I从excel成功导入数据，我创建了第一列的矩阵，称为能量（343,1）（x轴），同时创建一个称为时间延迟（y轴）的行矩阵（1,81）和一个（ 343,81）矩阵，第一列和第一行为零，称为吸光度变化（Z轴）。我已经得到了我需要的正确的3d图，但是我需要图中显示的轴是能量和时间延迟的轴，而不是吸光度变化矩阵的指数。我正在下面的代码的相关部分以及图表的图片：

EnergyString = dataArray{:, 1};
EnergyString(1,1) = {'0'};
Energy = str2double(EnergyString);
%Energy = [ Energy, zeros(343, 80) ];

TimeDelay = [ z1(1,1), z2(1,1), z3(1,1), z4(1,1), z5(1,1), z6(1,1), z7(1,1), z8(1,1), z9(1,1), z10(1,1), z11(1,1), z12(1,1), z13(1,1), z14(1,1), z15(1,1), z16(1,1), z17(1,1), z18(1,1), z19(1,1), z20(1,1), z21(1,1), z22(1,1), z23(1,1), z24(1,1), z25(1,1), z26(1,1), z27(1,1), z28(1,1), z29(1,1), z30(1,1), z31(1,1), z32(1,1), z33(1,1), z34(1,1), z35(1,1), z36(1,1), z37(1,1), z38(1,1), z39(1,1), z40(1,1), z41(1,1), z42(1,1), z42(1,1), z43(1,1), z44(1,1), z45(1,1), z46(1,1), z47(1,1), z48(1,1), z49(1,1), z50(1,1), z51(1,1), z52(1,1), z53(1,1), z54(1,1), z55(1,1), z56(1,1), z57(1,1), z58(1,1), z59(1,1), z60(1,1), z61(1,1), z62(1,1), z63(1,1), z64(1,1), z65(1,1), z66(1,1), z67(1,1), z68(1,1), z69(1,1), z70(1,1), z71(1,1), z72(1,1), z73(1,1), z74(1,1), z75(1,1), z76(1,1), z77(1,1), z78(1,1), z79(1,1), z80(1,1) ];
%TimeDelay = [ TimeDelay; zeros(342, 81)];

mesh(AbsorbanceChange)

title('WS2-Perovskite-image')
xlabel('Energy') % x-axis label
ylabel('Time-delay') % y-axis label
zlabel('Absorbance Change')

Answer 1

当我在MATLAB中输入help mesh时，我看到了这个：

mesh(x,y,Z) and mesh(x,y,Z,C), with two vector arguments replacing
the first two matrix arguments, must have length(x) = n and
length(y) = m where [m,n] = size(Z).  In this case, the vertices
of the mesh lines are the triples (x(j), y(i), Z(i,j)).
Note that x corresponds to the columns of Z and y corresponds to
the rows.

因此，你可以做到

mesh(Energy, TimeDelay, AbsorbanceChange);

我不知道你是如何read the data from file的，但是有一种比在代码中单独指定每个单元格更好的方法。
