MATLABdude said:If you only have one series of points (x, y, error) then you can use the default errorbar function, as per the examples on the help page below:

If you have multiple series to plot, you'll probably have to use the hold function (remember to turn it off if you need to replace the plot):

As for your other question about getting started in MATLAB GUI, I replied a while ago to another poster facing a similar predicament in a different thread (and some of the advice there may be helpful for you, as well):

Don't let it daunt you, and remember that the Mathworks has incredibly complete documentation and tutorials. When MATLABdude is a MATLABdud (which actually happens quite a bit), there's always the Mathworks documentation site (and other posters who didn't actually sign up with a username containing the name of a copyrighted program that they're not affiliated with).
Yes, you can use the errorbar() and plot() functions together to create a figure with both error bars and a line graph.
To customize the error bars, you can use the "fmt" parameter in the errorbar() function. To customize the line graph, you can use the "fmt" parameter in the plot() function.
Yes, you can add a legend to the figure by using the legend() function. You can specify the labels for the legend by using the "label" parameter in the errorbar() and plot() functions.
Yes, you can save the figure as an image file by using the savefig() function. You can specify the file format by using the "format" parameter, such as "png" or "jpg".
If your data has multiple sets of error bars, you can use the errorbar() function multiple times with different data and customizations to add all the error bars to the figure.
