Your series data shows the first timestamp for the date January 22nd. However, due to the min
parameter using Date.UTC(year, month, previousDay), it is actually referring to the date of January 23rd. This results in the graph omitting the first record from January 22nd because of the axis minimum value, and the same issue may occur with the max
parameter.
To address this, you can either remove the min
and max
parameters, or adjust them based on your series data to ensure no data is omitted. I hope this explanation helps clarify the situation.
