I see it working as follows:
The default behavior is the same as
your option 2 (height/width of the chart matches the height/width of the
window). If the user wants their chart to have specific dimensions,
they can enter the width and height into fields in the options panel.
Bear in mind that a user may want to collapse the options panel on the left for more screen space.

If you want to ensure that proportions are maintained (which may not be a bad idea), then 1 is most certainly the way to go.
2 doesn't seem to make much sense, why not just have a single box that lets you just resize it like any other window in any modern OS?
3 appears to be the cause of the change request, so obviously that's not an option unless a majority of people really want to keep it the way it is?
