I'm experiencing something really strange when using the chart with multiple series plugin.
The data originates from a couple of moisture sensors which will give a range of 0 to 1023 when connected to two Analogue inputs on the Arduino Uno. The thingspeak server accepts the full range on the first sensor (field3), but rejects the data for the second sensor (field4) if it exceeds 500. Is this a bug at the thingspeak end?
field1=20&2=45&3=1023&4=501 is rejected by the server but:
field1=20&2=45&3=1023&4=500 is accepted by the server
any number above 500 for &4 returns an error.
Has anybody experienced this?

Hi,

Is there an error when sending data, or when trying to plot it on the plugin? What is the error, and what channel ID is this for?

Here is a section of what is happening when sensor2 value is 500 (field4)

tcp connection succeeded
Sensor1 Value: 1023
Sensor2 Value: 500
Humidity = 51.70% Temperature = 22.20C
GET /update?api_key=YY3BB2A7F4MDOYZG&field1=22.2&2=51.7&3=1023&4=500
Returned from server number of data entries:[64]
*** tcp connection closed ***
**********************************************************
Change the sensor2 value to 501 and this happens:
tcp connection succeeded
Sensor1 Value: 1023
Sensor2 Value: 501
Humidity = 52.00% Temperature = 22.20C
GET /update?api_key=YY3BB2A7F4MDOYZG&field1=22.2&2=52.0&3=1023&4=501

*** tcp close error ***

The server is not returning the entry number.
