Does anyone know if the data output/ readings can be overlaid on top of each other? I need to see how the: TVOC(Ind30), TVOC(Ind40), CO2(ppm), PM2.5(pg/m^3), PM 0.3 count, PM1(pg/m^3), PM10(pg/m^3). Can be added to a single time line to see how they relate.
I am recording serious air pollution in a residential neighborhood and need to see how their emission types line up on the time line. I will be comparing to other local normal air data to provide contrast to their emissions.
I am a novice at programing, but am taking taking classes, and am guessing their might be away to lay the different data onto one time line?
Can anyone help out?
Can this be done on the Analytics Dashboard?
If so, I apologize for my newbie post!
Currently it can’t be done on our dashboard but you could export the data to Excel and then draw the chart there relatively easily.
Thank you for reading and responding to my question. I am not adept at Excel, yet, but I will try to figure it out. First, I will figure out how to export the data.
How to overlay? You mentioned programming. Many of my colleagues like using the analytical package ‘R’. I found python to be a bit more accessible for my project. In python check out the ‘Pandas’ library for working with columnar or tabular data frames. There are many data visualization packages to graph your data. For my time series project I used ‘matplotlib’ because it was the first one I tried. I used ‘plotly’ for another time series project. It worked well and seemed to be suited to use with web resources. Find something you are comfortable with and stick with it. Most of the data visualization packages in python have versions to work in R, or there is another equivalent.
Regarding finding correlation? You will be wise to brush up on your statistics skills. Again R has some excellent data analysis packages and there are probably equivalents in python. I’m not well skilled in stats, so good luck on your analysis journey.

Hi Derek, I really appreciate this feedback and guidance. Thank you.
I would love to have this feature as well! Its hard to see correlations sometimes. A quick fix could be to select multiple filters at the same time in the Analytics board. Maybe also a specific timeframe?

Yes, the option to select a time frame and choose which data is overlaid.
@Nilch-i-Ei-Iina @PaymentHippie @derek I think we can build a feature like this. What I envision is two drop-downs with the parameter (PM, CO/, VOCs etc) for primary and secondary axis and the rest like the current analytics page. What do you think?

That’s pretty good. The current time period/duration options could still be applied to the overlaid graph also?
Can you explain what you mean by ‘primary and secondary axis’?
The scale might be different. Eg RH 0-100 but CO2 500-4000. So having two axis would make it easier to compare.
oh, that’s right, the scales are all different… I have not figured out a solution to that issue yet.
I am documenting a local pollution issue for a lawsuit, so I have to make the data easy to read for the court, it has to show the frequency and duration of the emissions. I wanted to do an overlay, because they vary their emission type, but it still shows the frequency of emissions. Because it takes time for the air to clear and the pollution is chronic, it has been hard to get a baseline of what the normal clean air looks like. I have been able to register what clean air looks like once or twice in several weeks. I am trying to get some detailed local baseline readings from an area not exposed to acute pollution as a comparison.
The Analytics page has been helpful, but I could only snag screenshots from it.
