How to Review the Data on the Graph

Section 1: Displaying a Time Range

When visiting a Device’s page, the Device Overview page will provide a graph of data over time. 

  1. The selected time range of data is displayed on the graph, which can be adjusted by clicking into the Date Picker and selecting a different time range
  2. The variables will be displayed on the y-axis, and in this example temperature is displayed on the left y-axis and if there is another variable measured e.g., Relative Humidity we would see that on the right y-axis
  3. Time is displayed on the x-axis of the graph 
  4. Hovering over a data point on the graph will provide the channels name, the data point, and the time stamp is displayed below
Section 2: Down Sampling

As the time rang of data increases, the data displayed on the graph will be down-sampled. 

  1. A large range of data was selected in the example provided which is a 7-dar range of data that is displayed 
  2. We can see that the resolution has been down-sampled to a 15-minute resolution 
  3. Hovering over the data still displays exact data points that were collected 
  4. The graph lines may appear slightly blur due to the down sampling, but you have the ability to zoom (please continue reading below)
Section 3: Understanding Down Sampling

Zooming into the graph

  1. using your cursor, click into the graph and highlight the area that you would like to zoom into

After zooming in, you will see three graph lines for each variable depicting the average, high and low during the interval resolution displayed. In this example it is a a 15-minute resolution but as the data gets larger it can be a larger resolution such as a 1hour, 24hours, etc. resolution   

  1. The middle point that is shaded darkest is the average data point collected during the 15-minute sample period with the point above being the highest value collected and the lower point being the lowest value colleted 
Section 4: Resetting the Zoom
