How i make bars inside in multiple layer in Vegalite chart

I am trying to create a bar chart having multiple bar with dual y axis in time series data. Issue is that when we try to create mutilpe bar and use xoffset the bar ran out of the canvas of chart. Editor link

I want both bar must be cover inside canvas irrespective of data count

Try setting a rangeMax.
