[Question] chart size / zoom

Describe your question

Is there a way to change the size in pixels of the chart? Or make it expand to fill the viewport? I also tried to zoom in with a ThemeRiver chart but it wasn't possible. Some charts have a way to select certain portions to zoom in but this one doesn't?

It makes something like a year's worth of data for 40 items (2hr interval) impractical...
