Handling of dates with no value when creating a date bar chart in Charts

Some data have skipped dates, as in the following data.

TrainingSession(date: formatter.date(from: "2024-05-12 07:37:30 +0000")!, maxRM: 10.0, totalVolume: 0.0),
TrainingSession(date: formatter.date(from: "2024-06-01 15:00:00 +0000")!, maxRM: 10.5, totalVolume: 105.0),
TrainingSession(date: formatter.date(from: "2024-06-03 15:00:00 +0000")!, maxRM: 10.0, totalVolume: 100.0)

In this case, the graph shows nothing for the corresponding date as shown in the image. s it possible to create a continuous graph by displaying only the data with values and not the dates with no values?
