Hi. I want to plot in one logarithmic graph 3 different lines and a set of points. I have the part of the code down below to be more specific about my problem. As you can see, the x axis is logarithmic but the y axis is not. I dont understand what is wrong about my code. If you have any answers, please help me.

Thank you!

在 MATLAB Online 中打开

x = linspace(2,6,50); % use linspace

@Christos the variable y may not be needed, as you are evaluating y values using 3 different equations.

Use of linspace is better in this context, since you intend to use loglog function to plot your data.

the y axe is indeed in log scale , but the y range is not very wide , so you may have seen it as a linear scale , but is not

otherwise your "lines" would not appear as straight lines

The y axis is logarithmic. It's just not very obvious due to the limited range of your y data. Note the difference in the spacing between 240 and 260 vs. the spacing between 400 and 420, for example.
