I am currently running a longevity test with four units which are responding to an application of gas periodically (although the intervals between the gas applications are not consistent!). I have plotted the data into the graph below:
Does anyone know of a way in which I can filter the peak readings so I can show a trend line and proceed with further analysis? Most of the data points are nearing the minimum readings of each unit, therefore any line of fit for the data set appear right at the bottom of the graph:
I am able to do this manually, however as this needs to be repeated throughout the test it can get quite tedious. Thanks in advance!
