Error Bars, Please!

[mcogilvie]

I know this may seem arcane, or opening up to feature creep, but if I could just have error bars, I would be so terribly happy.... and so would a lot of scientists and engineers who just want something simple.

[Cortig]

I couldn’t agree more (and just sent a feature request by e-mail in this regard). We do need error bars. StDev or SEM (though if I have a column to enter it, it doesn’t really matter to you whether they are StDev or SEM), and top , bottom, or top & bottom error bars…

Pllleeeeaaassssseeeeee!!!!!!

Error bars should be priority one on development.

Error bars would be great! Especially assymetric ones! I'd would be great to be able to specify, how much the error bar should go up (e.g., +1) and how much it should go down (e.g., -1.6). I'm using statistical techniques that can create assymetrical confidence intervals, so that's why I'm craving for this. Thanks!

[Cortig]

I completely agree, I also sometimes have assymetric error bars actually,

[sculwell]

+1 to this!

It's actually pretty easy, just requiring a bit of repetitive line creation in the current version of OmniGraphSketcher. Read more on our blog post:

Thanks a lot for the link to the tutorial Robin.
It's a bit tedious for large datasets obviously, but at least it's an option :-)

I just discovered your application on the Mac App store and it would be absolutely perfect for the post grad course I'm doing ...if only I could add horizontal error bars too. Any chance?

[dave_m]

Horizontal bars are possible with a little bit of "cheating". Use Arrange > Swap axes to pivot your data, then add vertical error bars, then rotate back. I hope this helps! Let us know if you have questions or get stuck.
