Are there some search engines where I could search for graphs by specifying the axis I am looking for? E.g. axis 1: year; axis 2: price to store 1 TB on a hard drive.

  • Search for the raw data (timeseries, tables, values) in studies/statistics oneself and prepare the graph oneself or
  • do a simple Google image search like graph hdd storage price.
