Line Graph has dots?

I am using Power BI Desktop and am trying to create a line chart with varying interval durations. The interval durations are the way they are for a reason. 

However, the line chart is not connecting the dots as I want it to. I am guessing it is because they are different interval durations along the x axis. Is there a way to get around this without having to change my data source? Like I said, the interval durations are the way they are for a reason.

Here is a OneDrive link to the data source if you can use OneDrive.

Just upload that to a new .pbix file and create the graph using the following settings:

The graph produced is shown below:

As you can see, the graph above has a line graph with dots on it because of varying interval durations.

I would like to be able to have a line graph with lines using the data from the graph with varying interval durations. Like I asked, is there a way to do this without having to change my data source?
