The chart builder view displays in Workbench, in all Workbench (Wb)Web profiles, and with NiagaraAX-3.2 and later, the Default Hx, and Basic Hx profiles, as well.
The following description discusses the Chart Builder view in terms of the Wb Web and the desktop Workbench display profiles.
Stations using NiagaraAX-3.2, can display the Chart Builder view in the browser using the Default and Basic Hx (non-Java applet)
profile views. Views displayed using Hx look different but behave very similarly to the Workbench view. All field descriptions
apply to both views.
The Chart Builder Workbench view (also Wb Web profile view) is shown in Figure 135, the Chart Builder Hx view is shown in Figure 137. Using this view, you can select the histories (or in AX-3.5 and later History Nav Shortcuts), title, and configure the charts that you want to generate.
The display of the Chart Builder view is divided into three primary areas:
-
Display configuration fields
-
Time Range
Select a time parameter option from the list, including an option that allows you to set a specific time range using the Edit Time Range dialog box.
-
Title
Type a title for your chart in this text field.
-
Grid Lines
Select
ShoworHideto show or hide grid lines on the history chart. -
Rollup
Rollup (or Rollup Interval) is an interval of time that is used to determine what (and how) data is presented in your chart. Each point displayed, using the rollup, represents a designated time interval before the specified plot time. A rollup value of 1 hour will present data at a granularity level of every one hour, while a rollup value of 15 minutes will show data for every 15 minutes of logged data. Rollup options are:
-
Average
This option plots the average value for the selected rollup period.
-
Min
This option plots the minimum value for the selected rollup period.
-
Max
This option plots the maximum value for the selected rollup period.
-
Sum
This option plots the total of the values in the selected rollup period.

Histories pane
This is the lower left area of the Chart Builder view. It displays all histories that are available in your local station or any station histories that you import by means of the Niagara network or other network driver (for example, BacnetNetwork). Histories are grouped under the station by station name. Double-click (Wb Web profile) or click (Hx Web profile) on a history name to copy it to the Current Charts pane.
The histories that are displayed in this pane are the same histories that are displayed under the history space node in the
Workbench nav sidebar.
-
Current Charts pane
This pane displays the histories that are selected to be plotted. For each history, you may select the type of chart to generate, using the chart type option list, as displayed in Figure 138.
NiagaraAX-3.2 has more chart type options than earlier versions.
Adjacent to the histories in this pane are icon-type controls that allow you to reorder histories in the pane or remove histories from the pane.
-
Control buttons
The following control buttons are located at the bottom of the Chart Builder view:
-
button
Click this button to build the chart using the histories that are in the selected Current Histories pane.
-
button
Click this button to remove all histories from the Current Histories pane.
-
Figure 139 shows an example of chart that displays two histories.
When charting multiple histories that include different timezones, the Chart Builder uses a “zoneless” time range configuration so that it can plot each history with reference to its own timezone. This means that the resulting charts are aligned by local time. For example, if you select a time range of 8:00 AM through 5:00 PM for two histories—one in EST and another in CST—then the values at 8:00 AM align so that the 8:00 AM values may be visually compared.
