plot(x, y1, "r--o") hold on plot(x, y2, "b--o") legend("sin(x)","cos(x)") 1. 2. 3. 4. 5. 6. 7. 我们还可以在绘图注释中使用变量的值,方法是将字符串与变量串联起来: data = rand(5,10); sample = ["A","B","C","D","E"]; bar(data(3,:)) title("Sample " ...
set(gca,'DataAspectRatio',[2 1 1])%数组中三个值分别代表x、y、z轴的比例,如果想等比例显示,设为[1 1 1]即可,效果等价于axis equal 分析总结。 setgcadataaspectratio211数组中三个值分别代表xyz轴的比例如果想等比例显示设为111即可效果等价于axisequal结果...
How I can create contour plot like figure above with data below 테마복사 x=[53 59 62 68] y=[9.9 9.5 9.8 10.2] z=[1 3 5 10] xv = linspace(min(39), max(62), numel(4)); yv = linspace(min(29), max(52), numel(4)); [Xm,Ym] = ndgrid(xv, yv); Zm = griddata(...
t = linspace(0,10,500); y = sin(t); hf = figure; plot(t,y) XYZdata = Fun_GetFigDat...
XYZdata = Fun_GetFigData(hf); 结果:返回值 XYZdata = [Xdata Ydata],第一列为X轴坐标数据,第二列为Y轴坐标数据。 3.2 提取单坐标轴双曲线二维图原始数据(横坐标相同) 登录后复制t= linspace(0,10,500);y1 = sin(t);y2 = cos(t);hf = figure;plot(t,y1,t,y2) ...
(default for 3-D plots) % 'NorthWestOutside' outside top left % 'SouthEastOutside' outside bottom right % 'SouthWestOutside' outside bottom left % 'Best' least conflict with data in plot 与绘图中的数据冲突最小 % 'BestOutside' least unused space outside plot %% 背景颜色 set(gcf,'...
读取完数据之后需要对数据进行处理，具体的处理方式是：提取以0.002为采样周期的数据，分类存储起来。
MATLAB不但擅长於矩阵相关的数值运算,也适合用在各种科学目视表示(Scientific visualization)。本节将介绍MATLAB基本xy平面及xyz空间的各项绘图命令,包含一维曲线及二维曲面的绘制、列印及存档。 基本XY平面绘图命令 Plot 是绘制一维曲线的基本函数,但在使用此函数之前,我们需先定义曲线上每一点的x及y座标。下例可画出一...
how do I plot 3D xyz data from excel? Like with my data, I would like to take the data points, 302 of them, to be exact, from an excel spreadsheet, and then graph them to see a 3D plot. I am going to be using this plot to get the velocity, as this would be ...
