My log has been filling up with this error:
Warning: Too many datapoints to plot (142076) - Chart 1 not created
The number in the log increments for each log entry. My intention is to sample the values at 15 second intervals and keep 120 days of samples so i can analyze data later. I then have a chart set up (hopefully properly) to display the last 24 hours. So if it's sampling every 15 seconds, that should be 5760 datapoints. I'm not really sure how many is too many to plot. Is it some fixed number, or related to the chart setup?
I assume Chart 1 is the first one in the list. (Feature request: use the chart name instead of it's index in the error messages) I just noticed that on the device page, it's showing that this chart hasn't updated since Sept 12th. So that must be the one. It uses my "HVAC" database. It tracks 5 devices and has the following settings:
[DBTable1]
Name=HVAC
PurgeDays=120
Timer=1
Data1=$dvr:362
Data1Label=Calculated Average Indoor Temp
Data1Multiplier=1|
Data1MaxValue=110
Data1MinValue=0
Data2=$dvr:373
Data2Label=Dining Room Temp
Data2Multiplier=1|
Data2MaxValue=110
Data2MinValue=0
Data3=$dvr:376
Data3Label=Family Room Temperature
Data3Multiplier=1|
Data3MaxValue=110
Data3MinValue=0
Data4=$dvr:364
Data4Multiplier=1|
Data4Label=Cool Setpoint
Data4MaxValue=110
Data4MinValue=0
Data5=$dvr:363
Data5Label=Heat Setpoint
Data5Multiplier=1|
Data5MaxValue=110
Data5MinValue=0
The Chart setup looks like this: I'll be honest that some of these settings confuse me and I don't have a good grasp on how all of the settings are supposed to work.

As a side note, the x axis labels have never worked correctly. Every point shows 00:00 across the bottom.
