Layout.height is undefined when field is not dirty


I am using ‘react chart plotly editor’ for my webapp, but I got the problem what ‘layout.height’ is not always filled… it is filled when the textfield ‘Fixed Height’ is dirty (when you click on the textfield…)… Is it possible to get the ‘layout.height’ anyway (so: also even the textfield is not dirty), because my app responses strange because layout.height is undefined… in other words: is it possible to get all the params of the plotly chart at any time?

I hope to hear from anyone…
