    A sample burndown chart for a completed iteration. It will show the remaining effort and tasks for each of the 21 work days of the 1-month iteration. A burndown chart or burn-down chart is a graphical representation of work left to do versus time. [1] The outstanding work (or backlog) is often on the vertical axis, with time along the horizontal.

    en.wikipedia.org/wiki/Sample_preparation

    In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .
