Analysing the data • Use the button “Functions” to get to the instruments that enable finding and exporting data • • • Developed to view the most important data of ONE single publication in the database Provides a list of ALL the results of measurement data of ALL publications in one project Provides a list of ALL the results of the timeline data of ALL publications in one project Lay-outs equiped to search AND export data to excel: • Provides a lay-out to search the data on measurement results within one project on ONE single parameters that reports on measurements. • Provides a lay-out to search the data on timeline results within one project on ONE single parameters that reports on measurements. • Provides a lay-out to conduct a more complex search. Search results are reported in a next lay-out of which measurement results can be exported • Provides a lay-out to conduct a more complex search. Search results are reported in a next lay-out of which timeline results can be exported
