Having charts/table stay in place when using input controls

I am creating some dashboards with tables and charts using WebI. I have used relative positioning on some other dashboards, but for this one particular one, I have been asked if I can keep the set size of the charts and tables so they don't automatically adjust when you use input controls that bring up different data. I know you can turn off the autofit width and height for the cells, but this still doesn't keep the chart the same size.

As an example, I have a chart that displays the top ten of a count. The customer always want ten lines to appear within the chart, even if there is no data to populate based on how much is selected within the input controls. Basically like a frame that never moves.

Can this be done within WebI?
