About the All Tags category

If you want to compare tags that are measured by different units of measure, you can select a special category called All Tags from the Search Results area. All Tags is a special category that combines all numeric tags with different units of measure.

Note: Other products, including AVEVA Historian, use the term "analog" instead of "numeric". If your data is sourced from an AVEVA Historian, your associated analog tags will display here.

This category includes every numeric tag that results from your search query.

For example, the chart below is created from the All Tags category. This chart shows various weather-related tags that are each measured with a different unit of measure. In this case, you can see cloudiness and humidity (as percentage), atmospheric pressure (as hPa units), wind speed (as mph), and temperature (as degrees Fahrenheit) all on one chart.

For this chart:

• Each tag and its corresponding Y-axis are color coded.

• The tagname and corresponding color display at the bottom of the chart.

• The maximum value (rounded up) for each tag and corresponding color display at the top of the chart. The minimum value (rounded down) for each tag is displayed directly below the tag's maximum, near the X-axis.

• The X-axis (horizontal) shows a timeline while the Y-axis (vertical) shows tag values.

• Values for all tags display when you hover over the chart. Move the cursor back and forth to see values for specific points in time.
