If you have already selected which pages you want to print for this chart, use this option to scale the elements to a size where they just cover all the selected pages. Note that this function does not move the elements to the selected pages.

Enter the width and height (in number of pages) of the area which you want the elements to fit into. The size of the pages is determined by settings in "Edit | Page setup".

Enter the scaling factor. For example, 50% will make the elements half their current size, 200% will make them twice their current size. Minimum scaling is 1% but if you need a smaller percentage you can use the Scale to fit command more than once on the same elements.

If the overall shape of your chart (or selected elements) is not the same as the shape of the selected pages, the chart will become squashed either horizontally or vertically when you scale it. To prevent this, set the "Keep aspect ratio" option. This will maintain the shape of the elements and the overall shape of the chart.
