XY Plot

The XY Plot content option is a scatter chart that lets you see correlations between a single tag (X-Axis) to group of tags (Y-Axis). For example, see the relationship between temperature and pressure.

When selecting tags, only analog tags are available and the last tag selected is used as the X-axis.

Although the chart doesn’t show time, the data points are taken from the same point in time so that you can see correlations. When there is a stored value at a given point in time, the stored value is used. However, when there isn’t a stored value for a given point in time, the value is calculated using the linear or stairstep interpolation method.

To access the XY Plot option, select the Visualization content type when creating new content. Then customize the presentation of your data from the Content Settings pane. For example, change which tag to use as the X-axis, autoscale either axis, and show lines between data points.
