+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
+
+```
