Question

我想绘制两个因变量，电子温度和电子密度与高度的关系，如图中所示。

Temperature = [1215.91011364417 1850.01332752710    396.195674732049    2.33318763425785    367.128785760659    1.12519845278610    1041.54280237670    308.561781429331    1403.27246459229    914.721893718804    1131.60868755734    1.12519845278610    614.410587642758    1.46315184861483    1639.85277962398    1.12519845278610    1298.88722417057    1031.22681754873    1436.00999906341    1668.58036010507]

所有三个变量都是1x20。

任何帮助将不胜感激。感谢

此代码显示包含您提供的数据的图。我创建了两组轴，每组包含一个数据。第二组轴在顶部具有x轴，并且是透明的。

hold all

% first axis, first plot

ax{2}.XScale = 'log';

% Overlap both axis
ax{1}.Position = ax{2}.Position;

% Clean it up a little bit
ax{1}.XLim = [ 0 3000];
ax{2}.XLim = [1e10 5.3e10]; % You might want to change units here?

在matlab中在二维图上绘制两个因变量对独立变量？
