Prevent plot generating a line from end to end?

I am trying to plot a set of data with HVPlots that is basically 2 distinct sets of data, which have overlapping but not similar X-axis values. For example, one set of data might have x values that the other set does not. My problem is that one data set will generate a giant line from the lowest available data value to the largest available data value, which is not desirable.
Is there a way to prevent this giant line from forming? The data comes from a Pandas data frame. Thank you in advance.
Here is the CSV data, sorry for large text blob.

Solution
That line coming across is joining two different charts. The data contains 2 "Sensors" which have (technically) overlapping x axis values.
what you need to do is filter out the data by Sensor, and plot them individually.
data[data.Sensor.eq('Hyperion')] this will give you data filtered only for the "Hyperion" sensor.
you can do the same for all unique sensors, and then plot them as individual trances on the same x and y axis to get a multi lined chart.
