一
二维绘图基本语法
2D Drawing Basic Syntax
plot(X,Y) 创建Y中数据对X中对应值的二维线图。要绘制由线段连接的一组坐标，请将X和 Y指定为相同长度的向量。要在同一组坐标轴上绘制多组坐标，请将X或Y中的至少一个指定为矩阵。plot(X,Y,LineSpec) 使用指定的线型、标记和颜色创建绘图。plot(X1,Y1,...,Xn,Yn) 在同一组坐标轴上绘制多对x和y坐标。plot(X1,Y1,LineSpec1,...,Xn,Yn,LineSpecn) 可为每个x-y对组指定特定的线型、标记和颜色。可以对某些x-y对组指定 LineSpec，而对其他对组省略它。plot(X1,Y1,'o',X2,Y2)对第一个 x-y 对组指定标记，但没有对第二个对组指定标记。legend为每个绘制的数据序列创建一个带有描述性标签的图例。subplot(m,n,p) 将当前图窗划分为m×n网格，并在p指定的位置创建坐标区。gtext(str)在使用鼠标选择的位置插入文本str。当鼠标指针悬停在图窗窗口上时，指针变为十字准线。将鼠标指针移至所需位置并点击图窗或按任意键gtext(str,Name,Value) 使用一个或多个名称值对组参数指定文本属性。plot(X,Y) creates a 2-D line plot of the data in Y versus the corresponding values in X . To draw a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.plot(X,Y,LineSpec) creates a plot with the specified linetype, markers, and colors.plot(X1,Y1,...,Xn,Yn) plots pairs of x and y coordinates on the same set of axes.plot(X1,Y1,LineSpec1,...,Xn,Yn,LineSpecn) assigns specific line styles, markers, and colors to each x-y pair. You can specify LineSpec for some x-y pairs and omit it for others.plot(X1,Y1,'o',X2,Y2) assigns a marker to the first x-y pair, but does not assign a marker to the second pair.legend creates a legend with descriptive labels for each plotted data series. subplot(m,n,p) divides the current figure into an m-by-n grid and creates the axes at the locations specified by p.gtext(str) Inserts the text str at the location you selected with the mouse. When you hover the mouse pointer over the figure window, the pointer changes to a crosshair. Move the mouse pointer to the desired location and click the figure or press any keygtext(str,Name,Value) specifies a text attribute using one or more name-value pair arguments.
