先把代码贴上
1 clear all; 2 %%确定横坐标的范围 3 x=[8 20 36 24 12]; 4 t=0:0.1:3; 5 t1=randn(1,1000); 6 x1=[-2+3i,+4j,1-7j]; 7 real=[-2 3 1]; 8 imag=[3 4 -7]; 9 %%绘制二维图形 10 subplot(3,4,1); 11 pie(x,[0 0 0 0 0]); 12 title(\'饼状图\'); 13 subplot(3,4,2); 14 bar(x,\'group\'); 15 title(\'垂直条形图\'); 16 subplot(3,4,3); 17 bar(x,\'stack\'); 18 title(\'累加值为纵坐标的垂直条形图\'); 19 subplot(3,4,4); 20 barh(x,\'group\'); 21 title(\'水平条形图\'); 22 subplot(3,4,5); 23 barh(x,\'stack\'); 24 title(\'累加值为纵坐标的水平条形图\'); 25 subplot(3,4,6); 26 stairs(t); 27 title(\'以序号为横坐标的梯形图\'); 28 subplot(3,4,7); 29 stairs(t,sin(t)); 30 title(\'以X为横坐标的梯形图\'); 31 subplot(3,4,8); 32 hist(t1,(-4:0.1:4)); 33 title(\'概率分布图\'); 34 subplot(3,4,9); 35 compass(x1); 36 title(\'以实部为矢量\'); 37 subplot(3,4,10); 38 compass(x1,2*x1); 39 title(\'以复数坐标系的原点为起点\'); 40 subplot(3,4,11); 41 feather(real); 42 title(\'以实部为矢量\'); 43 subplot(3,4,12); 44 feather(real,imag); 45 title(\'以复数坐标系的原点为起点\');
结果:
