    The result:

    The date on the X-axis is continuous, however, the value of the corresponding Y-axis is empty.

    In order to eliminate the gap between data, you can modify

    double thedate = date.ToOADate();

    with

    string thedate = date.ToShortDateString();

    However, the result will look like this,
