Buildings.Utilities.Plotters

Package with blocks to create plots

Information

Package with blocks that allow generating time series and scatter plots, and writing these plots to one or several html files. The plots can be deactivated based on an input signal and a time delay, for example, to plot data only while the HVAC system operates for at least 30 minutes.

See Buildings.Utilities.Plotters.UsersGuide for instructions.

Extends from Modelica.Icons.Package (Icon for standard packages).

Buildings.Utilities.Plotters.Configuration

Configuration for plotters

Buildings.Utilities.Plotters.Configuration

Information

This block can be used to globally configure the parameters for the blocks from the package Buildings.Utilities.Plotters. Use this block for example to set the same plot file name and sampling time.

To use this block, simply drag it at the top-most level, or higher, where your plotters are.

Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).

Parameters

Labels
TimeUnit	timeUnit	Types.TimeUnit.hours	Time unit for plot
Activation
GlobalActivation	activation	Buildings.Utilities.Plotters...	Set to true to enable an input that allows activating and deactivating the plotting
Time	activationDelay	0	Time that needs to elapse to enable plotting after activate becomes true [s]

Connectors

Type	Name	Description

Buildings.Utilities.Plotters.Scatter

Block that plots one or multiple scatter plots

Buildings.Utilities.Plotters.Scatter

Information

Block that plots n time series that are connected at the input port y against the independent data that are connected at the input port x.

To use this block, set the parameter n to the number of time series y that you like to plot against x. Then, connect the signals for the independent data to x and the signals for the dependent data to y.

There can be multiple instances of this block. If they share the same value for fileName, then they will add their plot to the same output file. For convenience, we recommend to drag an instance of Buildings.Utilities.Plotters.Configuration at the top-level of your model. This instance can then be used to globally set the fileName and the samplePeriod for all plotters.

Extends from Buildings.Utilities.Plotters.BaseClasses.PartialPlotter (Partial block for plotters).
