You got me on this one.. I think this is something to do with having 2 ranges that the control due to rubbish coding on my behalf can not make fit...
Can you post some code that generates this?
Thanks

Hi,
You are using a second axis, which means sasqChart is trying to find an axis which fits both the first and the second series. Unfortunatly this bit of code is rather shoddy and gives up if it can not find a good scale after a few hundered iterations.
I have been trying to fix this code for 2 years, but have never been able to get a dataset that causes the issue apart from my initial set some years back.
Can you tell me the range of numbers you are using on both axis please?
Thanks
Steve |
