Johnson Steel owns and operates a factory that has a major piece of equipment that manufactures steel products that must meet certain tensile strength tolerances, which indicate at which force the steel product will break. Like most equipment, it is subject to the effects of wear and tear, which result in the tensile strength not being consistent over time. As a result, a quality control process has been put into place where the actual tensile strength of steel samples is taken and recorded into a spreadsheet. A chart has been created to give a visual representation of the tensile strength compared to upper and lower limits that are calculated.

The task in this project is to create a box in the top left of the chart that a user can click, enter the tensile amount from the last quality control sample, have a message clearly appear to indicate if the amount is above or below the limited established, and have the chart updated with the new amount. In addition, another box should be created in the upper right of the chart that would allow the user to remove the most recent sample amount taken, in case there was an error that needed correcting.
