Plot two lines. Specify the legend labels during the plotting commands by setting the DisplayName property to the desired text. Then, add a legend. 画两条线。 通过将DisplayName属性设置为所需文本,在绘图命令期间指定图例标签。 然后,添加一个图例(legend)。 % Plot two lines. % Specify the legend...
Plot Multiple Lines Define x as 100 linearly spaced values between −2π and 2π. Define y1 and y2 as sine and cosine values of x. Create a line plot of both sets of data. x = linspace(-2*pi,2*pi); y1 = sin(x); y2 = cos(x); figure plot(x,y1,x,y2) Create Line Plo...
Tiled graphs can be displayed using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 2-by-1 tiled map layout. Call the nexttile function to create the axes objects ax1 and ax2. Plot random data in each axes. Add a legend to the upper plot by specifying ax...
网格线(Grid Lines):使用 grid on 或grid off 命令可以显示或隐藏网格线。 轴范围(Axis Limits):使用 xlim 和ylim 函数可以设置坐标轴的范围。例如,xlim([0, 10]) 和ylim([0, 1])。 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...
plots several lines obtained from the columns of X, Y and Z. Various line types, plot symbols and colors may be obtained with plot3(X,Y,Z,s) where s is a 1, 2 or 3 character string made from the characters listed under the PLOT command. plot3(x1,y1,z1,s1,x2,y2,z2,...
polarplot(theta1,rho1,LineSpec1,...,thetaN,rhoN,LineSpecN)指定每个线条的线型、标记符号和颜色。 polarplot(rho) 按等间距角度(介于0和2π之间)绘制rho中的半径值。 polarplot(rho,LineSpec)设置线条的线型、标记符号和颜色。 polarplot(theta,rho) draws lines in polar coordinates, where theta represents...

2 然后将数据拖入到matlab中,在workspace中生成一个n×3的数组。3 然后可以先看看数据XY的情况,由于是一系列的点,这里我们使用点来表示plot(bb(:,1),bb(:,2),'b.');这里用做例子,所以点位排列非常有规律。4 接着可以开始坐XY的范围,并对XY进行插值,根据点位的多少,不要插值太稀或太密...
plot(axes_handle,…) h = plot(…) hlines = plot(‘v6’,…) 描述: plot(Y)如果Y是m×n的数组,以1:m为X横坐标,Y中的每一列元素为Y坐标,绘制n条曲线;如果Y是n×1或者1×n的向量,则以1:n为横坐标,Y为坐标表绘制1条曲线;如果Y是复数,则plot(Y)等效于plot(real(Y), imag(Y));其它使用情...
of the lines. For example, plot(X,Y,'LineWidth',2,'Color',[.6 0 0]) will create a plot with a dark red line width of 2 points. Example x = -pi:pi/10:pi; y = tan(sin(x)) - sin(tan(x)); plot(x,y,'--rs','LineWidth',2,... ...
