Origin Pro 8.6G, WinXP

I noticed a strange behaviour in one of my graphs, where one error bar is wrong:



The one line that is visible of the error bar is bigger, than the error bar should be. And it is influenced by the setting for the width of the markers for the error bar, that should only affect the (in this case) vertical lines of the error bars.

As soon as I change the scale of the bottom axis the error back is back to normal:



Jone of the five columns has a wrong error bar. The last but one has an error bar that is of similar size, but is completely visible.

Known problem? Intended behaviour? Bug?

Thanks in advance!

Kind regards,
Johannes

I sent the file to tech support, and got an answer (some time ago, was kinda busy...).

They suggested to scale up the error bars, as the error values are too small to be displayed.

I replied that this is no solution IMHO. The error bars of the other bars are displayed correctly, and their values are also very small compared to the mean value. If the error is that small, it should not be displayed. But a wrong error bar? If this is not intended behaviour then this is a bug.

Pimping my data (even with a small remark on the graph about scaling error bars) just because Origin has a bug in displaying error bars? Hell no.

Regards,
Johannes
