XY ErrorBar Plot

Hello,

I'd like to plot some scientific data in a XY-Point chart. Each Point should have an error-bar in the y direction.

First of all it is a bit inconveniet that one needs two series (Point and Error) to draw the measured data and the corresponding (measurement) error.

But unfortunatly I ran into the problem, when adding an second error series to the same chart. The Error bars are no longer on the correct x-value position but are left and right beneath the x-value (see image below).

I suppose this is because the Error-Series inherited the Bar-Series.
I haven't found any error Series or work-arround to solve this problem. Have you any suggestions?

Thank you,
Marcus

Hi Marcus,

When there are two Error series, there is something a X displacement for the Error series in order to be drawn one next to the other for a same X value. I've added to the wish list the possibility to force the X position independently of the number of Error series in the chart (TF02014232).

Dear Yeray,
Thanks for the reply.
Maybe you could also add to the wish list an combined Points- and Error- Series. This would be much easier than keeping two independant series syncronized and uptodate.

Hi Marcus,

Yes, it could be an interesting new feature for a further release (TF02014234).

Hello Marcus,

This is just to let you know we've just implemented the ErrorPoint and ErrorPoint3D series. They will be available with the next maintenance release and they look as follows:
