Parent topic: Analyzing Data
To start analyzing historical periodic data, load a feature in the Trend viewer. You can then load the corresponding data set in a waveform, spectrum, or other sensor data viewer. In other words, the Trend viewer serves as a master viewer for the workspace because you load and browse feature trends to see sensor data.
Complete the following steps to load a trend and view the sensor data that comprise the trend:
|Tip To load data from multiple features in the Trend viewer, <Ctrl>-click to select multiple features or <Shift>-click to select a range of features.|
|Note If a viewer remains empty, it might not support the sensor whose features you loaded. Refer to Unsupported Sensors for Sensor Data Viewers.|
The following workspace shows the result of selecting a feature from the asset tree. Notice the trend plot includes a point for each acquisition over a period of several days. The waveform and Spectrum viewers display the sensor data acquired at the position of the cursor within the Trend viewer.
Some sensor data viewers display data only when the Trend viewer contains features from certain sensors. Consider the following examples:
In this situation, sensor data viewers remain empty until you load features from supported sensors in the Trend viewer. Refer to Available Viewers and Options for Configuring Them for sensor support considerations for each viewer.
Although you have access to all data stored on the NI InsightCM Server, the following factors can affect your ability to load the data:
To view the trend and sensor data acquired during only a specific stream-enabled operating state, load a stream recording instead of loading a feature.
