scaleFactor for exporting

[davidpham87]

Hello,

Is there a way to specify the scaleFactor from Vega-Embed for exporting the visualization to png?

Best regards,
David

I just added this for 0.7.0, which will be released shortly.

It will be in hc/default-opts:

(def default-opts
  {:vgl {:export {:png true, :svg true}
         :scaleFactor :SCALEFACTOR  ; <----- defaults to 1
         :editor true
         :source false
         :renderer :RENDERER ; either "canvas" or "svg" - see defaults
         :mode :MODE}        ; either "vega-lite" or "vega" - see defaults
   :tab {:order :row
         :eltsper 2
         :size "auto"}})
