Issue with Chart.JS Plugin and SQL Data Retrieval

Hello :sunny:
I have downloaded the Chart.JS plugin.

I am currently trying to set up a simple bar chart to display the volume for the current week, aggregated per day.

I am using the SQL plugin to retrieve data from my database. The column I´m trying to summerize is decimal in SQL and number on the plugin.

The results on my graph do not match the actual data recorded. As you can see from the image, it returns data in the past on dates where there is no data yet.

Can someone point me in the right direction on what I might be doing wrong?
