SUMMARY

The discussion centers on creating scatter plots with error bars in MATLAB, specifically using the 'errorbar' function for vertical error bars and a user-defined function 'herrorbar' for horizontal error bars. The user aims to represent data points as (x, [y ± σ]), where σ denotes the standard deviation. This approach allows for a clear visualization of uncertainty in the data representation.

PREREQUISITES
  • Familiarity with MATLAB programming environment
  • Understanding of scatter plot visualization techniques
  • Knowledge of statistical concepts, specifically standard deviation
  • Experience with error bar representation in data visualization
NEXT STEPS
  • Explore MATLAB's 'errorbar' function documentation for advanced usage
  • Research user-defined functions in MATLAB for custom error bar implementations
  • Learn about statistical data visualization techniques in MATLAB
  • Investigate best practices for representing uncertainty in data plots
USEFUL FOR

Data analysts, statisticians, and researchers who need to visualize data with uncertainty in MATLAB, particularly those working with scatter plots and error bars.

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
