I've recently been working on plotting data with error bars in Mathematica and I ended up building a package to extend included ErrorBarPlots package's functionality.
As compressed file formats are not allowed as attachments (despite being listed on Wolfram Language Documentation as the how to post post states), you can find a functional and documented version of this package and quick demo here. I'd be glad to get your opinion and feedback, so I encourage you to try it in case you are interested.
There is more info in zipped documents (check the readme and the demo), but the key points are:
Hope you find it interesting!
I plan to create either a website or a Github repository soon, I'll post any information here when it's ready.
On the other hand, I have just tried the package in M10 and though it works, graphical appearance should be revisited (the package uses M9 themes for default plotting at the moment and that is not as attractive). I'll be working on that also soon.
Very nice, thanks for sharing, Guillermo! Do you have a webpage for this project where you maintain versioning and updates? Also is this compatible with M10?
thank you for your contribution and sharing! As you can see right under the title of your post, we added it to Mathematica Add-Ons group where all types of additions to standard system are collected and discussed.
