Side by Side Bar Chart - Using Deneb - Using a common Y axis

[dkernen2]

I have created an HCONCAT in Deneb of two bar charts, but I need them to utilize the same Y axis.  The bar charts should use measures.  I'd like to be able to have the same axis so that it could be sorted, and both charts would sort the same.  It's possible that some of the categories could have null values for one of the measures, which is why it's important that they share the same axis.  I've tried to bring the y encoding out of the layers/facets but I've not found the solution.  

I have created a small sample dataset.  https://kauffman.box.com/s/4dble8w64y9nfeakpirsyjnrs1ogehe7  Does anyone have any tips to make this possible?  Thank you in advance!

Hi @giammariam I've tried to change the height to be variable, so that the bars fill the allotted space, but they remain a fixed height.  I've tried to put a height declaration in "spec" as well as the "height" overall, but I cannot seem to get anything to work.  Where can I make the height so that I either it is dynamic with however side the user uses in the GUI OR set it to a fixed size and then use a formula so that the bar height relates to the number of categories?  Do you have any ideas?  You appear to be superhuman in your VegaLite!

Hey @dkernen2, thank you for the .pbix, all the detailed info, and the tag. Let me know if this is what you're after: 

Changes: 

• Added resolve to make the y-axis and y-scale shared
• Set the second chart's y-axis axis to null
• (optional) increased the spacing between the charts from 20 (default) to 40
