Order of rendering

[samselikoff]

I have an interesting problem. I have a BarChart, and I'm mixing in a Legend. Ideally, I'd like:

• the legend to render, and report back its width (which depends on the labels on the data it gets from the bar chart),
• update an asideWidth property on the bar chart, then
• render the bar chart

Right now the bar chart renders first. Is there any way I can render the mixin first? Alternatively, how could I calculate the width of the layer before it is rendered, and share that information with the bar chart?
