Control: Datalog Chart
 |
|
Description
The Datalog Chart control is used to plot data from selected Datalogs by pulling values from the database.
The time range of data to plot can be modified during operation but care should be taken for large data sets as plotting thousands of data points can take a very long time.
The auto update feature allows automatic refresh of data and care should be taken to not set this frequency lower than the time it takes to draw the data (for example update frequency is 1 second and time range is 24 hours).
Creation
Open the destination window to add the Control.
From the Toolbox, select the Control icon, move the pointer into the window and drag out the initial position and size for the control.
Access
If the Property Editor is not displayed, click on Ribbon > Home > Property Editor
Click on the Control. The Properties for the control will appear in the Property Editor panel and allow changes to be made.
