Welcome to the community! I was able to visualize your table by making the datetime field as a discrete dimension. Let me know if the attached workbook works for you.

Thanks very much for the response. This is what I was looking for. What is the distinction between the "discrete dimension" functionality you suggested and the default behavior I was experiencing?
Discrete and Continuous Fields
Fields are also either continuous or discrete, and this is indicated in Tableau by color. Green indicates a continuous field; blue indicates a discrete field. Colors appear on the icons next to fields in the Data window, or on the pills that represent fields that are used in the view.
Most often, dimensions are discrete fields, and measures are continuous. Therefore, when you drag a discrete field to a view, it adds category headings. A continuous field adds a scale. This distinction exists in Tableau so that you can convert dimensions to continuous fields or measures to discrete. For example, the views below both show profit as a function of order amount. In the view on the left the order amount is shown as discrete headers, one for each value. On the right, you can see that order amount is shown along a continuous axis.
To convert a discrete field to continuous, complete the following task.
- In the Dimensions pane, right click the field and convert a its data type to Number.
- Right-click it again and select Convert to Continuous.
