MATLAB 绘制折线图

大家好，又见面了，我是你们的朋友全栈君。

想要绘制出如上图所示折线图，首先，先展示代码：

x=0:10:50;
a=[0, 1.80,7.60,17.40,31.20,49.00]
plot(x,a,'s-g','MarkerSize',2,'MarkerFaceColor','g','MarkerEdgeColor','g','LineWidth',2);
grid
b=[0,1.10,4.20,9.30,16.40,25.50];
hold on
plot(x,b,'s-y','MarkerSize',2,'MarkerFaceColor','y','MarkerEdgeColor','y','LineWidth',2);
c=[0,1.10,4.20,9.30,16.40,25.50];
hold on
plot(x,c,'+-b','MarkerSize',1.5,'MarkerFaceColor','b','MarkerEdgeColor','b','LineWidth',1.5);
d=[0,0.20,0.40,0.60,0.80,1.00]
hold on
plot(x,d,'s-k','MarkerSize',2,'MarkerFaceColor','k','MarkerEdgeColor','k','LineWidth',2);
e=[0,0.10,0.20,0.30,0.40,0.50]
hold on
plot(x,e,'s-r','MarkerSize',2,'MarkerFaceColor','r','MarkerEdgeColor','r','LineWidth',2)
xlabel('Number of participant','fontsize',22,'FontWeight','bold','FontName','Times New Roman') 
ylabel('Number of transmission   x10^3','fontsize',21,'FontWeight','bold','FontName','Times New Roman')
h=legend('LGHW13','HSXL16','CM17','HSL17','Ours',loc = 0)
set(h,'Fontsize',16,'FontWeight','bold','FontName','Times New Roman');
set(gca,'FontSize',20,'LineWid',2);%设置坐标轴字体打下以及网格粗细

1. 设置x轴的数值：0到50 ，间隔为10
2. a相当于第一个函数y值，b第二个函数y值，依次类推。
3. grid 是绘制后面的格子，grid on 有格子，grid off 没有格子
4. plot 是开始绘制，前两个参数是x 和y, 第三个参数是曲线的样式颜色，第四个是说曲线上的方块圆等的大小，下一个是说标志点的内填充颜色，下一个是边缘填充颜色。
   
5. xlabel 是设置x坐标轴标题的，包括文字的内容，大小，样式等等。
6. ylabel 是设置y坐标轴标题的，
7. 设置legend图例 ，其中的loc表示图例的位置，这个需要自己试试。

'best'         : 0, (only implemented for axes legends)(自适应方式)
'upper right'  : 1,
'upper left'   : 2,
'lower left'   : 3,
'lower right'  : 4,
'right'        : 5,
'center left'  : 6,
'center right' : 7,
'lower center' : 8,
'upper center' : 9,
'center'       : 10,

8. 图例中一行set是对图例中文字的说明。
9. 最后一行是设置坐标轴上刻度字体大小，LineWid 是设置网格的粗细。

附上论文中两图代码，以供回忆
