Is there a way to dynamically resize width and heights of individual charts within a composed view?

[jw5]

I pack a variety of charts into a single page. Occasionally, I would like the ability to increase the size of one of the charts to improve readability or for screen capture.

I found that I could set a global width parameter to control the width of a single chart. Open the Chart in the Vega Editor

But I was unable to find:

• Anyway to use the interactive width other than at the outermost layer.
• Anyway to used named versions of width.
• Selectively apply param width to only named views.
• Find a definitive specification of "width":

Here is sample of the problem: Open the Chart in the Vega Editor

It appears that

• the width of chart_0 gets initialized with the initial param width value, but then never changes.
• The full view is affected by changes to width.
• If the charts differ in height spec at all, everything breaks :-(

I tried dozens of combinations adding width specifications like fit, fit-x, container, ... with no success.

What I wanted, but found through trial and error was unsupported, was a way to use expressions in my per chart width and height specifications with automatic layout after updates. This would give me a simple way to use an interactive scaling slider: 0.5--5X.

Thanks,
Jim

I should have added that if I could just interactively control the outer width and height and everything grew/shrunk to accommodate it that would be an acceptable solution.
