Use dual cursors on line charts

Using dual cursors on a line chart allows you to calculate the data between two frames. Historian Client Web will do calculations of the data based on the position of the cursors. It calculates the start/end cursors, then calculates the maximum, minimum, average, and delta value based on the position of the cursors.

To begin, select the Add Cursor icon in the top left corner of the line chart. You can then select two spots on the line chart to place the cursors.

Note: You will not be able to view any data in the Cursor panel until two cursors have been placed on the chart.

Select Cursor from the top right of the screen to open the Cursor panel.

Expand a data tag to view the start/end values, maximum, minimum, average, and delta information.

You are not able to save your dual cursor position. When you switch the Y-Axis type between Single and Multi, the cursors will remain in place. However, if you switch to another content page the cursor positions will not be saved.
