Chart commands

Options in the Chart view Command Bar allow you to fine tune data presentation.

Note: Most options in the Command Bar provide fine tuning for viewing purposes only. Changes made with those options are of a temporary nature and are not included when the chart is saved or exported. For example, if you turn on time zoom and Delta using buttons in the command bar and then export the chart, the chart file displays with the original default settings for those options. Exceptions to this are changes made with the Time Range, Sampling, and Status Coloring options, which are included on export or save.

To export the chart and retain all of the changes that you have made, you need to do the following:

Export the modified chart to a Station File.
Create a Px view for this chart and load the exported Station File to this Px view. The chart will display with the modifications included.

Figure 2. Narrow chart width changes the chart display (Niagara 4.6 and later)

Any time the chart width is less than 800 pixels the following changes in the chart occur. This prevents the chart from appearing overcrowded which helps maintain legibility. Once the chart window is resized to greater than 800 pixels, the changes revert.

Chart title and data series legend become hidden.
Several of the commands icons move from the chart Command Bar into the Settings window.
In the Settings window, a right-click menu is available on data series in the Series window. The right-click menu allows you to hide or show specific data or even completely remove data from a chart.

Command Bar	Default	Description
Add Series	opens separate Nav tree	Adds components to the chart. Select one or more components via the File Chooser. Use `Ctrl` `+` `Click` to select multiple individual components or select a folder that contains multiple components.
Save Chart	opens save window	Available only when you open an existing .chart file and make changes. Saves the file (chart or csv format) to the station File space (Files/charts/chartName.chart or Files/csv/chartName.csv ).
Export Current View or Object	opens exporting window	Available in a new chart and when you open an existing chart file. Select Exporter opens a window to choose the exported file type. Options are Chart (default), CSV, and, in a browser connection, Print is also available. Ord Type selects the type of ORD: Absolute or Relative (default). Note: In Niagara, there is added support for relative ORDs to better accommodate Px page reuse. Base Ord specifies a base ORD from which to relate all of the ORDs in the series for that chart. This option applies only to chart exports with the Relative Ord Type. Select Destination provides two options: Download or Station File. Download exports to your Windows file system. Station File exports the file to the station File space (Files/charts/chartName.chart) or (Files/csv/chartName.csv) File Name View On Export
