If you are overlaying one gauge chart with another and using background transparency to make the bottom one visible, note that background transparency is not retained when charts are exported as images from QlikView. You can test this without involving NPrinting (RMB on the object and choose Export). So I would say this is not possible.
HTH - Daniel.
As Daniel said transparency is not supported. What i did in my development was:
I have created a Pie/Donut Chart with 2 Dimensions and fidly expressions. Two dimensions wereartifitial Calculated dimensions so i could write conditional statements and link them with very fidly expressions. The trick was to make expressions independent and ignore dimension levels. This was not an easy part and i remember spending whole day playing with it and trying get it working, but eventualy i did
Attached chart is obviously not end result but it can give you an idea what you can do and how you can achieve similar thing using PieChart as a single object If you really need to have wrapped together gauges.
Apologies for such a late reply - i had to think twice or even more times to actualy get to where i was.
So first thing first. The solution i have implemented was not based on Pie Chart but on Radar chart.
Here are the steps to do:
- create grid used as a main dimension in your radar chart (usually 100 unique values is enough, in my example i have 500
- create 2 measures (to create 2 lines)
- play with the colors
My example is based fully on variables and x field with values from 1-500.
See attached solution - it is basic but does the job.
