Hello,
In order to display your data point-by-point, you will want to modify your graph/chart properties on the front panel of your VI. First, [right-click] on the graph display within the front panel, select [Properties], and select the [Plots] tab. Now, you will want to select the �pt-by-pt� icon and select a suitable data point display format (see attached image, I chose hollow points to display data).
Now, your plot will be represented pt-by-pt, and you will be able to easily differentiate between discrete data points.
I hope this helps! Please let me know if you need further assistance.
Best Regards,
