Hi I am looking for a way to plot my old measured data alongside my target/upper/lower lines on the same chart. The target occasionally changes which is why I am not just using a Axis reference line.
Simplified, my data table has the below columns:
| Measured Value | Date & time of measurement | Target (at time of measurement) | Upper limit (at time of measurement) | Lower Limit (at time of measurement) |
I have made a paint rendition of roughly what i hope my output will look like when plotted:
