An additional button Load Last Used is available in the graph browser window for vertical cursor, by clicking this button, the graphs which are linked last time will be loaded and be ready to be linked.
If the graphs are already linked, when the cursor is moved on one graph, data coordinates from all data plots and from each of the linked graphs will be displayed. Furthermore, when a tag is added to/deleted from the graph with the cursor, corresponding tag is added to/deleted from each of the linked graphs.
After the graphs have been linked together, an icon will be added on top-right of all graphs to indicate which graphs have been linked together. Right-click this button, a context menu to control the cursor line will be brought up and you can:
- Go to Cursor Line Window:
