Buildings.Utilities.Plotters.Examples.ControlsVerification_CoolingCoilValve
Validation model for the cooling coil control subsequence with recorded data trends
Information
This model validates the cooling coil signal subsequence implemented in Building 33 on the main LBNL campus. Data used for the validation are measured input and output trends with 5s time steps, starting at 2018-06-07 00:00:00 PDT. The trends were exported from the ALC EIKON webserver.

Buildings.Utilities.Plotters.Examples.Scatter
Simple scatter plots
Information
This example demonstrates the use of a scatter plotter
that plots (sin(t), cos(t), which will be a circle
with radius 1,
and (sin(t), cos2(t), which will be an arc
above the x-axis.
The plots will be in the file specified
in the plot configuration plotConfiguration.

Buildings.Utilities.Plotters.Examples.SingleZoneVAVSupply_u
Scatter plots for control signal of a single zone VAV controller from ASHRAE Guideline 36
Information
This example demonstrates how to create a scatter plot that shows
for a single zone VAV control logic
the heating and cooling set point temperatures, and the fan speed,
all as a function of the heating and cooling control signal.
The sequence that will be used to plot the sequence diagram is
Buildings.Controls.OBC.ASHRAE.G36_PR1.AHUs.SingleZone.VAV.SetPoints.Supply
and shown below.
The plot will be generated in the file plots.html.
