Hans,

Sorted. It wasnt the quotes, it was the fact that I had not rounded it down!! (as per the Airlink doc ) :bash:

Non 100% because of all the stop starts while fault finding!! :groan:

On the Airlink graph view page is there any way of configuring it.
1) The reference lines are too prominent for me so I would like to alter the density
2) Any way of setting a standard output to limit the number of lines . (I know you can cancel them when displayed but would like to choose what is the standard display.

Item 1) more important than 2)!! ;)

See the AirLink parameter section. So your point 2 is solved I assume ;)

I will make the thickness configurable. I'll send you a beta soon so you can use it.
It will be published in the next release to be available for all

See above. Btw: you already disabled the NowCast line, you can disable all in a similar way.

[Edit:] Please note that the referencelines are on Z-plane 0 so all plotlines run before them. Also note that these are pretty complex charts because it is the same code used for In/Out and 2.5/10 , so I will not make it super flexible.

Hans,
Thanks..
See the AirLink parameter section.
Not quite what I wanted so I'll live with it. Want to keep all of table but want to reduce lines on graph to just one or two, without
having to de select at bottom of graph. I appreciate that it (charts) is a complex matter so no problem.
I will make the thickness configurable. I'll send you a beta soon so you can use it.
Thanks...

Hans,
Just for your information:
After doing some "Googling " I added the following correction equations to my python script for the PMS5003 Particle sensor to compensate for humidty.


//Correction algorithm thanks to help of Zbyszek Kiliański (Krakow Zdroj)
pm2p5 = pm2p5/(1.0+0.48756*pow((humidity/100.0), 8.60068));

pm10 = pm10/(1.0+0.81559*pow((humidity/100.0), 5.83411));


Probably not really required since the units are low end but made me feel good ! :D

Mike,

I have been experimenting a lot with T/H corrections. Second order equations and more complex like yours. As long as it is done on the sensor level (so before sending the the value to CMX) you can do what you want.

To give it some truth you will have to calibrate such equation against devices used by your national institute concerned with particulate matter measurement. Here in the Netherlands some have done that in a citizen science project.

Understanding and having it ready indeed feels good :D

Edit: and I forgot to say that there ia a Polish sensor which corrects by heating the air before it enters the sensor
