We currently have a number of tags that we are only generating the historical data for from the previous day. The graph is then trending the data up until a certain time. The problem I am having is that from the last timestamp point where data is being trended, the graph continues to trend a flat line which is then reconfigured once the data comes in the next day. Is there a way of having the graph stop trending completely from the last timestamp until the following day when the new set of data is imputed?

If you are using the Easy Chart check to see what Line Style you are using for that particular tag. Right click on the component and select Customizers > Easy Chart Customizer. Edit your pen and you will see the style. If you set the style to Line w/ Gaps the graph will detect a large gap and will not connect the lines. Let me know.
