Level-Time chart

Back to the overview

A Level-Time Chart loads the configured measuring channels first. Subsequently the user can limit or move the display of the loaded time range.

Selection of the time range for retrieving from database

By default, only data are retrieved for the current year.
With the button  ,the dialog for selection of years can be displayed. These will be loaded from the database to the client, subsequently. With storing, the settings can be accepted. Please note the load times. The more years will be loaded, so the load times will take longer.

Selection of time range of the display

The to displayed time range can be limited or extended on different ways.

Set fix time range (day, week, month, …)

With the toolbar and the buttons        the time range of the current display can be set. Thereby means 1 – day, 7 – week, 31 – month, 4 – quarter and 12 – year. With the arrow buttons      you can skip about the select range back, forward or to beginning or end.

Click with pressed left mouse button in the chart area to move the range for or backward. Alternatively you can use the “Brushbar” (5) under the time axle to select or move a time range with mouse.
