In the Chart properties set the X-axis type to float. Then when you execute the code wire an empty array to the HistoryData property.

I can't seem to figure out what you mean. I have no formal training with labview. It's taken me a long time to write the simple program I've attached. Any further guidance would be greatly appreciated!

Its pretty normal for a newbie taking time to write code. Right click the Waveform chart>Create> Property node>History Data, you will get a property node, keep that at the start of the code and create a constant. You can also go to the VI properties and>Execution and select "Clear Indicators when called".

 

I would recommend you to go through LabVIEW basic materials which will give you an understanding about the basics concepts/components of LabVIEW.
