In the top right area of the tab axis you could define the min/max/interval values of your scale whereby min/max is usually something like:
The interval might be set manually if the span between min/max could be estimated and didn't change much by different selections. If not you need to set something like this: round((max - min) / NoOfInterval).
Beside this removing the time-part from the dimension and/or using a different and shorter formatting of the dimension-values will increase the space for the lines and with this the readability of the information.
Yeah I'm aware of the static min max values. What I need is a dynamic min scalling so that all groups(2nd Dim) will be shown. I sorted those by size, the largest is at the bottom going all the way up to the smallest. I'm not however able to generate a function that gives me the min value of the largest group.
Setting those value static will not work as there are huge differences(10^5).
PS: The testdata has no time. However the real data will.
Thanks for your help. The culprit of my problem was one value in my test data which resulted in seemingly wrong results. Your solution is correct "MIN(AGGR(MAX(value), time_dim))". Sorry for the inconvinience.
