gcf: get current figure。 就是得到当前显示的图像,对应figure(1), figure(2)等 gca: get current axes. 得到当前显示图像中的小图像,对应subplot set set指令可直接设置某个对象的属性值,第一个元素为对象,第二四六等元素为属性名称,第三七九等元素为对应属性名称的属性值 设置图片大小位置 set(gcf,'unit'...
【 MATLAB 】gca 介绍(当前轴或图表) 查看原文 数据可视化之Matplotlib(2) plt.gca()获得,分别表示GetCurrentFigure和GetCurrentAxes。在pyplot模块中,许多函数都是对当前的Figure或Axes对象进行处理,比如说:plt.plot()实际上会通过plt.gca()获得当前的Axes对象ax,然后再调用ax.plot()方法实现真正的绘图。 举例1:...
Working with Multiple Figures Simultaneously Create two figures, and then create a line plot. The figures appear as tabs in a figure container. By default, the plot command targets the current figure. f1 = figure; f2 = figure; plot([1 2 3],[2 4 6]); Set the current figure to f1,...
clc;clear;close all; x=0:0.1:pi; y=sin(x)); h1 = figure(1); % 创建画布,画布编号为1 set(h1,'pos',[350 250 850 340]); plot(x,y,,'r-','linewidth',2,'Marker','s','MarkerFaceColor','w','MarkerEdgeColor','g','MarkerSize',10); xlabel('Time [% of stance duration]','Fo...
ax= gcareturns the current axes or chart for the current figure, which is typically the last one created or clicked with the mouse. ax= gca返回当前图形的当前轴或图表,通常是用鼠标创建或单击的最后一个轴。 Graphics functions, such astitle, target the current axes or chart. Useaxto access an...
gcf 返回当前Figure 对象的句柄值 gca 返回当前axes 对象的句柄值 gco 返回当前鼠标单击的句柄值,该对象可以是除root 对象外的任意图形对象,并且Matlab 会把当前图形对象的句柄值存放在Figure 的CurrentObject属性中。 1. 2. 3. 2.matlab下的图形对象
MATLAB 中gcf、gca 以及gco 的区别 1.三者的功能定义: 1 2 3 gcf 返回当前Figure 对象的句柄值 gca 返回当前axes 对象的句柄值 gco 返回当前鼠标单击的句柄值,该对象可以是除root 对象外的任意图形对象,并且Matlab 会把当前图形对象的句柄值存放在Figure 的CurrentObject属性中。
