sense has a responsive layout which means the chart will adjust its layout based on its size and the device the user is using to view it. You can put 12-14 charts on a single sheet but as you are seeing it's hard to display content cleanly and clearly at that size.
IF you have to display that made per sheet suggest you show users they can right click on the chart they are interesting in looking at and expending it to full size. This will give them the type of visibility they will want in a chart, Either that or as you've done spread over a number of sheets.
iI've an example of what's been suggested here
Uses an extension called as variables. For this to work your charts would need to be the same but the content changable.
ANother option you have if you have the skills is to create your own site and embed the charts Into it in a mash up. That will bypass the sheet restriction
Thanks Andy and other members.
So If i summarize it, I cannot increase the height of the work area, if i have to fit all components in 1 sheet then I have two options,
1) Use very small graphs and ask the user to increase it to full screen when analyzing
2) Use filters in my code so that user can toggle at run time to see.
