axis函数更适合综合调整多个参数。axis([010 -1.51.5])这种单行命令可同时限定横纵轴范围，调整坐标比例时用axisequal避免图形扭曲。在处理三维图时axisvis3d是必要选项，可以确保三维视角变换时保持比例稳定，这种参数化的设置方法在处理建筑图纸时尤为重要。动态调整则要结合hold命令的使用模式。实时系统采集数据时，...
Set Axis Limits Copy Code Copy Command Plot the sine function. Get x = linspace(0,2*pi); y = sin(x); plot(x,y,'-o') Change the axis limits so that the x-axis ranges from 0 to 2π and the y-axis ranges from -1.5 to 1.5. Get axis([0 2*pi -1.5 1.5]) Add Padding ...
Plot the Input variable on the x-axis and the Output variable on the y-axis. Return the Line object as p, and turn the axes grid on. Notice that the axis labels match the variable names. Get p = semilogx(tbl,"Input","Output"); grid on To modify aspects of the line, set the ...
调整线条样式可用plot(x,y,’r–’)。字母r代表红色，双短横线设定虚线样式。尝试不同组合：’b:’显示蓝色点线，’g-.o’生成绿色点划线并带圆形标记。线宽参数通过’LineWidth’设置，如plot(x,y,’LineWidth’,3)加粗三倍。配置坐标轴需调用axis函数。axis([012 -1.51.5])限定横纵坐标范围。xlabel(’...

画图操作重点在绘图参数设定，通过命令行产生正弦波，"t=0:0.1:10;plot(t,sin(t))"后会自动展示波形窗口。坐标系调整用坐标范围语句axis，窗口分为多个展示区时需用subplot提前分割。想导出图形保存有两种途径：使用主界面导出设置，或者打印命令直接另存为图片。常见问题对应四类解法：报错提示中含有缺失变量需要...
stem(Y) plots the data sequence, Y, as stems that extend from a baseline along the x-axis. The data values are indicated by circles terminating each stem. If Y is a vector, then the x-axis scale ranges from 1 to length(Y). If Y is a matrix, then stem plots all elements in a...
