I have a report where in the the report will be consisting of 32 different html5 line charts so it would require almost 450cm space so that none of the chart details missed. Do i have an option of increasing height of the report to 450cm??
You could let the page height unchanged, place each chart on a different page, and set the Ignore Pagination report flag to true. This will generate a single page document at runtime.
But you also have to take into account that some document viewers cannot display pages of 450 cm height.
