# SerialPlotter protocol
One message can consist of multiply parts.
One part can consist of one label, one label and a value or only a value.
| | |
| --- | --- |
| End of message symbol | \n |
| Part separator symbols | ' '(space), '\t'(tab), ','(comma) |
| Label-value separator symbol | : |
# Valid messages are
## Labels and value messages:
| | | | | | |
|-------------------|----|-------------------|-----|-------------------|----|
| Label : Value | | | | | \n |
| Label 1 : Value 1 | \t | Label 2 : Value 2 | | | \n |
| Label 1 : Value 1 | \t | Label 2 : Value 2 | ... | Label n : Value n | \n |
## Label only messages
| | | | | | |
|-----------|----|-----------|-----|----------|----|
| Label: | | | | | \n |
| Label 1 : | \t | Label 2 : | | | \n |
| Label 1 : | \t | Label 2 | ... | Label n: | \n |
There is a special case, the CSV header style.
| | | | | | |
|-------|----|---------|-----|---------|----|
|Label 1| \t | Label 2 | ... | Label n | \n |
But in this format, labels consisting of only numbers are not recognised as labels.
It is safer to just use the normal label only message.
## Value only messages Value
This is not recommended if you using a board with USB to UART converter.
Because when the label is sent, before you had the SerialPlotter opened, then the label/labels get/gets never set.
| | | | | | |
|---------|----|---------|-----|---------|----|
| Value 1 | \t | Value 2 | | | \n |
| Value 1 | \t | Value 2 | ... | Value n | \n |
# Examples
## Single Trace without label
This example plots on line on serial plotter without setting a label
```ino
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue1 = analogRead(A0);
Serial.println(sensorValue1);
delay(100);
}
```
The output looks like this
```
10\n
11\n
12\n
13\n
14\n
```
## Single Trace with label
This example sends the label once in the setup routine. Afterwards only the value is send.
```ino
void setup() {
Serial.begin(9600);
Serial.println("Label 1:");
}
void loop() {
int sensorValue1 = analogRead(A0);
Serial.println(sensorValue1);
delay(100);
}
```
The output looks like this
```
Label 1:\n
10\n
11\n
12\n
13\n
14\n
```
## Single Trace with label send every time
This example sends the label every time together with the value.
```ino
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue1 = analogRead(A0);
Serial.print("Label 1:"); Serial.println(sensorValue1);
delay(100);
}
```
The output looks like this
```
Label 1:10\n
Label 1:11\n
Label 1:12\n
Label 1:13\n
Label 1:14\n
```
## Two Traces with label send every time
This example sends two values together with the labels.
```ino
void setup() {
Serial.begin(9600);
}
float avg = 0;
void loop() {
int sensorValue1 = analogRead(A0);
// send lable and value seperated by ':'
Serial.print("Value:"); Serial.print(sensorValue1);
avg = (avg * 4 + analogRead(A0)) / 5.0;
// send part devider '\t'
Serial.print("\t");
// send the second lable and value
Serial.print("AVG5:"); Serial.println(avg);
delay(100);
}
```
The output looks like this
```
Value:377 AVG5:431.01
Value:338 AVG5:408.81
Value:392 AVG5:395.85
Value:583 AVG5:427.28
Value:221 AVG5:383.42
Value:195 AVG5:343.74
Value:202 AVG5:314.19
Value:209 AVG5:292.15
```
