In Deneb vega-lite for Power BI, I have ran into an issue where my data for a certain segment of data is not labeled as the beginning of the month (04/01) is not shown, due to the nature of this specific data.

I use Deneb Heatmap. When i dont use data labels it shows with correct sort, but when it comes to demonstrating data labels (in my code it is “days”) it is sorting alphabetically. I could not solve the issue. Please if anyone knows how to sort correctly, i’ll be happy
