Lab Report How do you plot error bars on LoggerPro?

[Smita]

I've managed to plot my graphs, but I'm mystified about how get the error bars there.

Thank you for your help!

you should probably convert it to excel;

at least we have to export ours from easyLog

or try youtube,

Go to Data > New Data set, this should add 2 new columns to your data (it's on the left for me)

After doing that, double click on which column you want to add error bars for, go to options, and tick the box that says "error bar calculations" and click on "use column:" and choose which of the new columns you want to use. Then add the uncertainties to that column, do the same for the other column if you want to. This method is for if you want to add different ucnertainties for each value. If you want the same uncertainty for all values, just go to the options for the column you want to edit, tick the box saying "error bar calculations", choose "Error constant +/-" and put the value you want for the uncertainty.

Sorry if my wording is confusing. Hope it helps!

Ah, perfect. It worked, thanks so much!! My error bars are slightly bigger than I expected, but alteast I have error bars. Thank you!

@Meat: that is actually a very good explanation of how to do it.

@Smita: if the error bars are big then investigate what the reason is and comment on it in the Conclusion/Evaluation/Improvement-parts of your lab report!

Good luck!
