Multiple line chart / sparklines with auto Y-axis

Hello friends,

I want to build multiple line charts based on some field (lets say Customer). Separate trend chart for each Customer.

I've tried Small Multiple Line Chart and a couple of other visuals - but all lacked the features I need.

I have found Inforaphic Designer which is cool, but I cannot find just one setting:

I am looking for a setting that will auto-scale the Y-axis for each multiple (currently all the charts start with 0)

I have found and un-checked "Uniform Y-Axis" and it solved the Maximum limit for Y-axis.

But I couldn't find anything for Min limit. I need it to be different - automatic for every multiple, not 0 for all….

Please help

Thanks!

Michael
