bode magnitude producing different plots for the same transfer function

2 views (last 30 days)
I have transfer function and have manually extracted the magnitude and plotted it. When I used the bodemag function however, the plot looks very different. Im confused as to which one is correct and why they are coming out differently, as I havent applied any unit conversions. For my manual extraction, I have used the following and its produced the plot underneath.
[mag phase] = bode(tf);
Mag = transpose(squeeze(mag));
However, when I use the bodemag(tf) function, I get this:
I dont understand why these reuslts are so different or which one is correct and am looking for some claririfcation.

The upper plot is plotted with a linear magnitude and the lower one is plotted with the magnitude in decibels.

Also, the upper plot x-axis is linear and the lower is log scale. And they don't cover the same max and min values.

Noted. I didn’t catch the frequency axis difference. I was concentrating on the magnitude axis.
