数据点标记(Data Points Marker):使用 plot(x, y, 'o') 可以将数据点标记为圆圈,使用 plot(x, y, '+') 可以将数据点标记为加号等。这些是常用的 plot 函数参数设置,通过结合使用这些参数,您可以创建各种外观和风格的图表。要了解更多关于 MATLAB 中绘图函数的信息,请参阅 MATLAB 的官方文档。相关...
以plot为例,假设你的Excel文件中有两列数据,你可以先将这两列数据导入到Matlab中,然后使用plot函数来生成二维图形。例如,假设你的Excel文件名为data.xlsx,A列是x轴数据,B列是y轴数据,你可以这样操作:1. 使用importdata函数导入Excel文件:data = importdata('data.xlsx');2. 提取A列和B列 ...
Each colored trace represents the spectrum of the activity of one data channel. The leftmost scalp map shows the scalp distribution of power at 6 Hz, which in these data is concentrated on the frontal midline. The other scalp maps indicate the distribution of power at 10 Hz and 22 Hz. ...
在matlab中查看Plot的数值点，即x、y坐标值的具体步骤如下：1、在图形界面窗口中，点击工具栏上的【Data Cursor】工具，然后再在需要查看坐标值的数据点上单击左键即可。2、选择【tools】菜单栏下面的【Data Cursor】选项，具体情况如图。3、最终效果如下图，在选中的数值点右上方，会显示出x、y坐标...
