Graphs
Several graphs provide a visual representation of the surveys tracked in the database.
The charts are generated using the Google Charts API based on test dates stored in the database. All tests are counted, including equipment calibrations. Since the amount of equipment calibration related tests is relatively small compared to the total amount of equipment, the effect of including equipment calibrations is negligible.
The Survey Count Graphs page shows a set of column charts of the equipment tests tracked by the application.
The first graph shows the total number of tests in each year for all the tests tracked in the application.
The following bar charts show the number of tests per month for each year of tests tracked in the application.
The Daily Survey Count Calendar uses the Google Calendar Chart to illustrate the number of surveys tracked on a daily basis throughout the year. The shading in each cell represents the number of surveys performed on that day, with darker shades indicating a higher number of surveys.
The Survey Category chart uses the Google Pie Chart to illustrate the number of surveys performed by survey type (Routine Compliance, Major service check, Acceptance, etc).
