Discussion Overview

The discussion revolves around creating a scatter plot that includes standard deviation as error bars, specifically focusing on both vertical and horizontal error bars in the context of numerical data visualization.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks guidance on how to represent standard deviation on a scatter plot, specifically wanting to show points with error bars as (x,[y ± σ]).
  • The same participant later clarifies the need for both vertical and horizontal error bars.
  • Another participant inquires about the tools being used for this task.
  • The original poster eventually reports success in using MatLab, specifically mentioning the use of the 'errorbar' function and a user-created function called 'herrorbar' for horizontal error bars.

Areas of Agreement / Disagreement

The discussion appears to be resolved for the original poster, who found a solution using MatLab, but no consensus on methods or tools has been established among other participants.

Hi, first of all, sorry if my English is not perfect I'm from Quebec City and English is not my first language.

I'm trying to make a scatter plot with average of numerical data. But now I also want to put the standard deviation on the scatter.

Exemple, I have a point (x,[y ± σ]) and I want to have a point on my coordinate (x,y) and a line that goes to x - σ to x + σ. Thank you

Sorry I forgot to say, I need vertical and horizontal error bars
 
What tool do you want to use to produce this?
 
Sorry I finally got it, I was working on MatLab and I used the function errorbar and a function made by a user called herrorbar for my horizontal
