basic graphing question

Jul 10, 2023 01:36 AM (382 views)

Hello! I'm new to JMP and struggling a bit. I have some data graphed ( voltage vs current density) and I'm trying to over lay the ideal diode equation. I can't figure out how to plot the formula over my data. Also I think I'm using the formula function right to take the log of the I data?

Hi and welcome to JMP! Looking at the data you provided, I think the only thing keeping you from making the graph is that your "log(I)" formula column is listed as Nominal. If you click the red icon to the left of the column name and select "Continuous," then the graph should work as you're expecting.

Also, assuming you're looking to calculate the log base 10 of the absolute value of the "I(A)" column, then you're using the formula function correctly.
