How can I include soil vapour data (ppm) on the Borehole log so that it appears as line chart?

I am working on borehole logs for environmental-related work. I have seen logs done by other consulting firms where the soil vapour data will be displayed as a line chart (similar to say atterberg limits for geotechnical boreholes). My question is how do I set up my logs to be able to do this? I have included a photograph of a borehole log I found through a google search to illustrate exactly what i mean by line charts in the log.
