berkeman said: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?

George Jones said:op amp data log - log plot that shows a constant gain over a certain frequency range,
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.NYAME EPHRAIM said: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 2 copies of the table in your first post are identical, right? I'm guessing it was an accidental duplicate Upload.NYAME EPHRAIM said:how can i input this in the same graph paper or i need to do it separate ?
When plotting a graph for opamp results, it is important to consider the range of values for both the input and output variables. The input variable is typically measured in volts, while the output variable is measured in either volts or decibels (dB). Choose an appropriate scale for each variable that allows the plotted data to be easily interpreted and does not cut off any important data points. It is also helpful to label each axis with the corresponding units.
The type of graph to use for opamp results largely depends on the type of data being plotted and the purpose of the graph. For continuous data, a line graph is typically used, while for discrete data, a bar graph may be more appropriate. If comparing multiple opamp results, a stacked bar graph or grouped bar graph can be useful. It is also important to consider the audience and choose a graph that is easy to understand for them.
The graph title should accurately describe the data being plotted, and the axes should be labeled with the variable name and unit. If multiple lines or bars are being plotted, a legend should be included to identify which data corresponds to which line or bar. It is also helpful to include any relevant information about the experiment or data collection process in the graph's title or caption.
Yes, there is a variety of software available that can be used to plot opamp graphs, such as Microsoft Excel, MATLAB, or Python. These software programs provide tools to easily create and customize graphs, as well as perform statistical analysis on the data. It is important to familiarize yourself with the software and its features to effectively create a clear and accurate graph.
To make your opamp graph visually appealing and easy to interpret, it is important to use clear and concise labeling, choose appropriate colors and fonts, and avoid cluttering the graph with unnecessary elements. You can also use additional features such as gridlines or trend lines to aid in interpreting the data. It is also helpful to follow basic design principles, such as balancing the use of white space and utilizing a consistent design throughout the graph.
