How can I plot a graph for these opamp results?

[NYAME EPHRAIM]

i have build and simulated the op amp circuit, i have recorded the voltage gain at different frequencies, now i need to plot a graph for the two results in same graph paper, i have not plotted a graph before for the related task so i need to understand from the basics,
i need some one to patiently help thanks.

Welcome to the PF.

What graphing program are you going to use to plot the results? Excel? Or does your simulator have built-in plotting capability? What simulator program are you using?

Welcome to the PF.

If you do use Excel, you can do a log - log plot that uses base 2 or base 10 for the axes. You do not have to use the same base for each axis. If you use minor gridlines, you can get something close to your image. Folks here can help you with this.

This is basic, textbook material, better taught through tutorials than through forum explanations. See, eg.,
https://serc.carleton.edu/mathyouneed/graphing/plotting.html
which starts right at the beginning and takes you through the process. It should answer all of your questions.

You can also plot graphs in spreadsheets (like EXCEL) and using various on-line tools, some of them free, others not. However, if you want a hand-drawn graph on an actual piece of paper, the link above should be enough to get you started.

I could be wrong, but I think

should not be interpreted as "I have not plotted a basic graph before". I don't see log log plots at your link.

@NYAME EPHRAIM wants to make an op amp data log - log plot that shows a constant gain over a certain frequency range, followed by a sharp break to a constnt roll off (on a log log plot), like in Figure 1.1 from

http://denethor.wlu.ca/pc300/opamps/opamp.pdf

His data nicely approximates the ideal case in Figure 1.1.

I have taught op amp labs to second-year engineering and physics students, and, at this stage, I expect that: 1) they understand basic graphing; 2) their reports should look professional; 3) they might need help producing a log log plot with software.

Thank Sir
please i need to be clear about some,
if you see my results data, i have results for 10k ohms resistor, and 100k ohms resistor,
how can i input this in the same graph paper or i need to do it separate ?

The graph paper you illustrate can easily carry two curves. Plot gain vs. frequency for the 100 kΩ case, then on the same axes plot in a different coloured ink your results for the 10 kΩ investigation.

The 2 copies of the table in your first post are identical, right? I'm guessing it was an accidental duplicate Upload.

If you are plotting in Excel, you would make 3 columns of data. 1st column is your frequency, 2nd column is your Vo/Vi for 100k, and 3rd column is Vo/Vi for 10k. Then select those 3 columns of data, and click the button to make a Scatter Plot. Select the smoothing graph version to make the plot. Then click each axis one at a time, and do "Format Axis" to change to log scale and choose your line spacing.
