A chart toolbar is configured via the Toolbar properties. The following table describes the buttons on the chart toolbar in the order they appear in run mode:

In run mode you might want to reconfigure a chart to receive its facility assignment from another control on the same screen. For example, a Tag Chooser can be added and configured to send facilities to an associated chart.

• In design mode configure a chart series to show data for a selected UDC, for example, Casing Pressure. Configure the chart to receive its facility and/or SiteService from the screen or another control on the screen, for example, a Tag Chooser.
• In run mode you can select a different facility in the Tag Chooser, which will send data for the same UDC for the new facility to the chart and dynamically update the chart accordingly, for example, Casing Pressure for facility A, facility B, or facility C, and so on.

To pause live updates in run mode:

• Click (Canvas Native view) / (CygNet TWC web view) on the toolbar to pause live updating for this chart.

To restart live updates in run mode:

• Click (Canvas Native view) / (CygNet TWC web view) on the toolbar to restart live updating for this chart.

See To configure live updates and date ranges for more information.

To change the date and time range settings for the current chart in run mode:

• Click (Canvas Native view) / (CygNet TWC web view) on the toolbar to open the Configure Time Range dialog box, where you can configure these properties.
  
• See To configure live updates and date ranges for more information.

To quickly view a predefined window of time on a chart, configure the toolbar's quick range buttons on the chart's Properties pane.

When clicked, each button will reset the time range presented in the chart based on the button's configuration. For a button configured for 8 hours, the chart’s time range will be set so that it begins 8 hours from now with the left edge of the chart representing now. For a chart configured to be in live update mode, the chart will update to show this 8-hour window. The quick range only persists for the current runtime session.

You can quickly cycle through various windows of data using quick range buttons. In the following chart, three quick range buttons give different views: a full chart (30 days of data), a 12-hour window, a 1-day window, and a 1-week (7 days) window.

The chart allows dragging, panning and zooming in the chart plot area to examine a dense area of data points that cannot be seen clearly at the normal chart scale. See the Drag mode, Pan mode, and Zoom mode for configuration properties. Dragging, panning, and zooming change the view — the current location and magnification of the screen. Every time you drag, zoom, or pan, you establish a new view.

Drag over an area in a chart

• If dragging is enabled for Pan and or Zoom, click within the chart and drag the mouse over the area you want to examine.
• The chart will redraw to the selected area and the scroll bars will adjust accordingly.
• Click (Reset to unzoomed state) on the toolbar to return a chart to its original state.

Pan in a chart

• If panning is enabled on either or both axes, a scroll bar will display next to the horizontal axis and/or the vertical axis.
• Click the white handles on the scroll bars to drag the horizontal axis and/or the vertical axis to the desired scale. Note that panning is disabled if the axis is at its maximum scale.
• Left-click in the plot area to drag the chart horizontally and/or vertically to view data points more clearly.
• Click (Reset to unzoomed state) on the toolbar to return a chart to its unzoomed state.

Zoom into a chart

• If zooming is enabled on either or both axes, a scroll bar will display next to the horizontal axis and/or the vertical axis.
• Left-click in the plot area and continue holding down the mouse button while you draw a zoom area. Release the mouse button when you have drawn the desired zoom area to view data points more clearly. You can zoom multiple times over the same area. The scroll bars will adjust the horizontal axis and/or the vertical axis scale accordingly.
• You can also use the white handles on the scroll bars to adjust the horizontal axis and/or the vertical axis to the desired scale in the zoom area.
• Click (Reset to unzoomed state) on the toolbar to return a chart to its unzoomed state. Note that you cannot incrementally zoom out.

By setting the Hover mode property in design mode you can highlight a series by hovering over it, and all others series in the chart will be faded.

Series editing is integrated into the legend; as you hover over the legend you can temporarily remove a series from the chart. Any series can be hidden on the chart during run mode.

• Click on the Check Box to the left of the series legend to hide the series. The series will be hidden on the chart.
• Click again on the Check Box to show the series.

As you hover over the legend you can remove a series from the chart completely. Any series can be removed from the chart during run mode.

• Click on the x to the right of the series legend.
• Click Remove to confirm the series removal. The series will be removed from the chart. If it is the last series on the chart, the axes will be removed as well.
• To see all series again, you will need to close and reopen the screen containing the chart.
