Hmm… I think its’t not works in previous version. Ok, I’ll check it some time
It looks like you have a very small values in your streams, like 0 and 0.0002 and due to formatting of labels they are shown as 0.
My device sends data with 0.01 step. But Float can be different, of course.
You know the truth as server owner.
I don’t see values larger than 0.003 in your charts data for the first stream
and only 0 and 0.0002 for the second one
I’m working on a fix to this issue
I have exported data to CSV. Here is not null values. Where you see values < 0.01?

3M: I see only '0’s
How can I add resolution? There are 0.05, 0.04 values from csv?
Not sure what do you mean. CSV should have the same values as the superchart has.
Change ‘decimals’ in stream screen to #.#### and look how it will be shown
nothing changes
Yep, I’ve missed that decimals param affect only values in tapnhold, the next build will have formatting of y values till 5 decimals.
There are 0.05, 0.04 values from csv?
Actual values - yep, but values calculated for given timeframe will be сalculcate as average, that’s why if there were 0 and several 0.01 - it could be less than 0.01
wouldn’t it be better to introduce engineering notation for such a small values?? It is kinda “unprofessional” to display labels like 0,00002. Where just a “clean” 2.0E-5 means the same.
Blynk has perfect design, unsupported for usually science software. 
@Dmitriy, @dontsov You are laughing guys, heh? But it’s not me, who tries to display virtually “zero” on chart!

tell them all… !
I’ve prepared a build with a better formatting of Y labels: https://www.dropbox.com/s/hpobett5o1nex4p/blynk-armeabi-v7a-fixes.apk?dl=0 - could you install it and check?
