Access the Trend Chart of Tag Values

About this task

This topic describes how to access the values of a tag in a trend chart. The difference in the timestamp of consecutive values depends on the time resolution of the tag. For example, if the time resolution is seconds, the timestamp of consecutive values of the tag will be one second apart.

You can plot the trend chart for up to 10 tags at a time.
