Charts embedding SDK

I then have a question about the embedding SDK. Firstly I got it right to filter 20 or so charts simultaneously by adding just one filter. Now I was wondering will it be possible to filter a chart on 2 fields (cross filter) using the SDK.And also to filter on 2 or more values within the same field. And then one frustration i seem to be having is with the sizing of the chart in the SDK. If I dont specify a height in px or vh it renders but you cant see it(basically a very tiny box) , and then if you adjust the size to much the value and the heading dont seem to be reacting in sync , sometime the heading is very far from the chart data or if i make it to big the data will fill the box completely and the heading will get lost.
