Peak time in a shop for each day

Dear all,
I’m using the last version of grafana … I’m trying to build a heatmap (or similar) to display the peak of customer in a shop for each hours / day in a week. MySQL return the data as below … I can’t manage to display the heatmap. I simply want the hours on “x”, the day on “y” et the nbre of this as value (for the color).

Something like that would be perfect … (if needed I can change my sql query)

Thanks for your help
