Graph Data

[Daniel716]

Why do you need to wait 20 min for the graph data to reset?

I am trying it now... I do know when you turn off graphing its says data is cleared but its not!

One of the DA guys said to wait 20 min then turn it back on?

has anyont done this?

I tried resetting data, but it's not going away. I'll just wait for the next update.

Have you noticed this one? For some reason my temp graph lost its resolution (pH graph is looking good, but old data still there, too).
Here's before update:

After with v1.0.2 update (NOTE: I've switch between one day and one week graphs....still, either 70-100 or 0-100 is your choice on y-axis):

Yeah, when I flashed upgraded, for whatever reason I could not compress my graph, reason there was "zero" recorded so it was already compressed.. I did disable/enable but nothing, then I disabled, next morning enabled and wammo works fine. Obviously that was more than 20 minutes, but yeah it will reset itself. My guess is that it needs a data point or two worth of time to realize it's not graphing anymore.

sfsuphysics -

Good to hear the reset worked out for you. I'm sorry the 20min reset wasn't long enough (that was the theoretical), we will look into improving the logging system.


Note to everyone-

Updating to the new versions for the SL1 and the PC4 shouldn't affect the graphing. This is handled on the Head Unit. The values to the left of the graph represent the highest and lowest points of data that were collected for your probe. If anyone gets a data point that is significantly higher or lower than the rest of the data, the graph will appear smaller (like a line).

Currently, there are two options to resolve this:
a) Stop logging the probe for an extended period of time and then re enable it. The time to wait is over 20 mins, and could be longer.
b) Wait for the outlying data to resolve itself. This could take up to a week as new data would write over it.

I hope this helps explain what people are seeing. As always we are here to help.

Ok bad news, reset reverted?, can't compress again. I recently plugged some new stuff in (a whole new PC4) so don't know what's the deal with that, maybe the addition of a new module threw a zero reading in there for a microsecond and got recorded.

I set up my RKE on my QT for a few hours before setting it up on my DT. The temps in my QT were around 82, while the temps in my DT are now around 80. I was graphing for a short while on the QT, and like others - have been unable to reset the data. I had the graphing disabled for a half hour, and I have yet to see the old data dissapear. No new data has appears on my graph, even when "zoomed" out. Just a blank gap.

I really like the RKE, but this graphing behavior is quite, um - lame. Shouldn't the head unit flush the data when graphing is disabled (like it says it has). Will this be fixed in the upcoming revs?

Also, will there be a capability for crawling the graph in order to see the values at each sample point? The units of the graph are difficult to decipher.


Thanks.

Temp and pH graphs still flat lining information even after disabling graph logging for almost a day before starting it up again. I didn't really expect anything to change with the PC4 1.0.3 updates, though.

So, the options are: wait for either 1) head unit firmware or 2) RKE compatible "myReef" application 3) another week for data graph to resolve itself (doubtful, since it worked for a few days last time and then flat lined)

Until then, I'll have to manually record data if I want to tweak my system's response to the summer months.

We are looking into solutions for the graph situation. Note that in an upcoming update to the head unit, you will be able to scroll through previous data.

Just an update: After two hours, my graph started to show the current data. I still cannot figure out what the exact values represented by the graph are, but it sounds great to hear that the graphing tool will be scrolling.

BTW: I would love to have an arrow cursor or vertical line that the user can pan left<->right along the graph to display the time/data pair for the cursor location. Also, full screen graphs would make better use of the limited screen resolution and thus offer more precision.

I'm seeing some of the graphing errors as well, even when disabling for over 24 hours the error comes back. Like others, my problem is mainly with the resolution. Could it have anything to do with wild temperature and pH swings that some are seeing? I see the temperature and pH sometimes make wild jumps that only last for a second or so. For instance, this morning, my unit was in an alarm state that I had set for temperature. The unit said that the alarm that set it off was 142 F! Maybe these wild, individual points, are causing the graph resolution to open way up, but since the points are so small they don't really show on the graph.
