Scroll only one series ?

Hi !

Lets say you have two series and both use the bottom axis. Is it possible to scroll only one series?

Example:
Both series have x values from 0 to 100. After scrolling series1 is still at position 0..100 and series2 is at position 10..110 for example.

I know that there is an axis scroll, but this would scroll all series because they all use the bottom axis.

Any idea ?

Hi Dominik,

If both series share same axis that doesn't make much sense to me as in some way you'd be changing dragged series values. To drag an entire series you can do something like what I suggested here.

Hi Narcis,

Code: Select all

that doesn't make much sense to me

Let me explain how you can use this feature ...

If you have a radio controlled airplane with a data logger for altitude, then you can see the climbing speed (how fast you increase your altitude). If you have two measurements you will have not exact fitting series. So you can change the x position of the whole series to get the climbing parts on top of each other.

Hopefully you understand what I mean

I do had some tasks where such feature could be useful, e.g for manual synchronizing two or more time series of simultaneous measurements, made by two different instruments having their own clocks (usually I shifted XValues for one of the examined series).
Imho, the simplest way to solve the problem in Dominik's definition could be use of invisible custom X-axis for one of the series.
However, it could be misleading for users, so I would suggest use of custom X-axis on the alternative side of Chart rectangle.
PS. Dominik, sorry if I didn't fully got your problem.

Hello,

What about using left and bottom axes for one series and top and right axes for the other. Setting all axes to automatic (default setting) might help you achieve what you request. Could you please try if this fits your needs?

Thanks in advance.

Hi !

Well the two series was only an example ...

I real there are a lot of more series. The minimum of series is about 5 or 6 !!

And I think it is not a good idea to use more then one bottom axis.
Is there no easy way to scroll only one series from a pool of series which all use the same horizontal axis ?

Hi Dominik,

The only way I can think of is modifying series values to fit the other series. Could you please send us a simple example project we can run "as-is" and I'll try to show you how to achieve what you request?

Thanks in advance.
