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
Click to add variables to the Graph.
# Select Site where the data is stored in
# 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.
# Initial Depth is optional. It will add an Anchor to the graph.
# Reference Point (Bottom/Top) is used to tell 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.
# Optional is the set the Depth and X Scale
# Optional is 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 then 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 Referance 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 should be in ascending order.
Now it is possible to move variables up or down if required.
To finish the setup next select the presentation tab to finish the setup.
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 and calculate the distance between them and compare the distance on the baseline.
