Help with Graphing with filtered dataset with null values in Ignition Reporting

I’m wondering about how I can configure this graph in Ignition reporting to display my data values properly. I have a filtered data set indicated in the top segment of both images where it does not record data in that time period from 86 to 76 F. The bottom segment of both images is the raw data set. I had my script stop recording data after 86 F and start again at 76 F, and this is further displayed in the second image. I want to change the graph so it displays two lines, one before I stopped recording data, and one after as opposed to having one downward sloping line that isn’t actually indicative of the data. How can I do this?
