How can I plot t versus log x(3) and log x(4) instead of plot(t,xa(:,3))and plot(t,xa(:,4)) contained in the code? can I write plot(t,log (xa(:,3))) and plot((t,log (xa(:,4)))? Thanks in advance.댓글 수: 0 댓글을 달려면 로그인하십...
semilogy(x, y):仅y轴使用对数刻度,x轴保持线性刻度。 例如,使用loglog函数绘制上述数据的对数坐标图: matlab loglog(x, y); xlabel('X'); ylabel('Y'); title('Log-Log Scale Plot'); grid on; 以上就是在MATLAB中绘制对数坐标图的基本方法和步骤。

set(gca,'yscale','log') set(h1,'Color','k') 1. 2. 3. 4. 特别值得一提的是,如果横坐标用的是z表示,而纵坐标用y表示,即为y=z(而不是x),那么要将横坐标改为对数坐标时依然用“xscale”不能用“zscale”(因为MATLAB默认x表示横坐标) ...

you max try the 'painters' renderer, it connects the points in the order they are listed. If your values are not sorted, it will bounce up and down the line plotting the points. When you switch your xscale, it highlights the subtle incontinuities in plotting the line this way.
