InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
As for computer tools, it depends on the tools available to you. Having Autocad on my computer, that's what I would use. It locks lines and intervals in place with mathematical precision. Free versions like LibreCAD are available. Powerpoint would also do a good job, but it would take more care to keep things aligned regularly.
