Displacement graphs can be created and configured in VDV.
To configure displacement graphs to Setup -> Displacement Graph.
Click + in the top right corner to create a new Displacement Graph.
Give the Displacement graph a name and add the type (Depth, Distance, Elevation and Convergence graphs).
Add the reference point (top or bottom).
Choose Depth Unit (Meters or Feet).
Angles (Displacement, Angles, Sin(Ang)).
Click to add variables to the Graph.
Select the Site where the data is stored.
Select the Baseline reading.
Click Select Variables to add Variables to the graph.
Use the controls on the right-hand side to set the location of each Variable.
The Initial Depth is optional and will add an Anchor to the graph.
The reference Point (Bottom/Top) tells VDV where to start to calculate the Cumulative movement.
- Bottom=Largest Number.
- Top=Smallest number.
Choose Graph type.
Displacement Cumulative = VDV Calculates Cumulative Displacement and subtracts the baseline reading.
Displacement Incremental = Incremental Displacement where the baseline is subtracted.
Deviation Cumulative = VDV Calculates Cumulative Displacement but does not subtract the baseline reading.
Deviation Incremental = VDV Displays the data as it is without any calculations.
- It is optional to set the Depth and X Scale.
- It is optional to change how many plots are shown on the graph. Default is to show the latest 10 plots.
It is possible to add multiple alarm limits, choose custom colors and line width.
Adding layers is done through the Layers Tab by selecting the Add button.
Give the layer a name and the appropriate configuration in width, select the pattern and color scheme and click Save.
The Limit Profile gives the user a chance to draw up a comparison line on the graph that can be visually compared to the data.
It is also possible to view SAA convergence data on the displacement graph.
Under the Configuration tab, select Convergence as the Type of displacement graph and select the Reference point as Top.
Select site and baseline, just like when creating vertical or horizontal displacement graphs.
When selecting variables for Convergence, it is required to select both dX and Z. The number of dX and Z must match and be in ascending order.
Now it is possible to move variables up or down if required.
To finish the setup, select the presentation tab.
Select the presentation type as Deviation Cumulative to finish the setup.
To view Displacement graphs, go to Displacement Graph in the left-hand menu in VDV.
Select what graph you want to view in the list.
When viewing Convergence graphs, the baseline is always visible.
Click any two points to calculate the distance between them and compare the distance to the baseline.
