Historical Chart Example
The following historical chart shows raw pressure sensor data (Well 05 Station) overlaid with a moving average (MA) of the last 5 values to show the trend.
The pressure plot was also overlaid with reference pressure thresholds (35 and 85) to see how often they are exceeded.
Finally, an additional y-axis was appended below with the rate of change of pressure (ROC) over the past 3 intervals. The ROC offers an additional type of indicator if something goes wrong.
