The hold on command is the culprit you're issuing it before you plot, so the linear axis is being held throughout. 1k次。MATLAB的semilogy命令绘制y轴对数坐标图不起作用_matlab中的semilogy无效 As you pointed out the semilogx function cannot work with x is 0. The reason is that you are using a logarithmic x -axis, and the first point has x =0, so the logarithm is −∞. However, if the axes hold state is 'on' before you call semilogx, the property does Your code works already in octave (and I don't have matlab at this computer), but I think the problem is that you do hold on before the first plot, hence preventing the initial axis to be created. semilogy (Y,LineSpec) The point that is being ignored is the first, not the third.
