Adding a value indicator below a graph BLE

[TorstenKlf]

There is an example on the phyphoxBLE GitHub that demonstrates how to mix view elements (and create multiple views): https://github.com/phyphox/phyphox-ardui...riment.ino

I know this example... and I finally got it working:
____________________________________________________________
#include <phyphoxBle.h>

int AnalogPin=27;
float Messwert;
float Magnetfeld;
float Offset;

void setup() {
    PhyphoxBLE:tart("Magnetfeldsensor_01");                //Start the BLE server

//Experiment
    PhyphoxBleExperiment experiment;

    experiment.setTitle("Magnetfeld");
    experiment.setCategory("Arduino Experiments");
    experiment.setDescription("Plot the magnetic field of a Hall sensor over time.");

    //View
    PhyphoxBleExperiment::View view;

    //Value
    PhyphoxBleExperiment::Value Value1;     
    Value1.setLabel("B = ");                           
    Value1.setUnit("mT");                   
    Value1.setChannel(1);

    //Graph
    PhyphoxBleExperiment::Graph graph;
    graph.setLabel("B over time");
    graph.setUnitX("s");
    graph.setUnitY("mT");
    graph.setLabelX("time");
    graph.setLabelY("B");


    view.addElement(graph);                //Attach graph to view
    view.addElement(Value1);
    experiment.addView(view);              //Attach view to experiment
    PhyphoxBLE::addExperiment(experiment);  //Attach experiment to server

    //Offsetkorrektur 
  Offset=0;
  for(int i=0;i<7;i++){
    Offset+=analogRead(AnalogPin);
    delay(10);
  }
  Offset=Offset/7;

}

void loop() {
Messwert=analogRead(AnalogPin);
Magnetfeld=(Messwert-Offset)*(-0.0492);
PhyphoxBLE::write(Magnetfeld);
delay(50);
}   
 
____________________________________________________
But the strange thing is that if I change details in the programm as e. g. some smoothing in the loop:

.......
 void loop() {
  for(int i=0;i<37;i++){
    Messwert+=analogRead(AnalogPin);
    delay(10);
  }
  Messwert=Messwert/37;
Magnetfeld=(Messwert-Offset)*(-0.0492);
PhyphoxBLE::write(Magnetfeld);
delay(50);
}   

the compilation stops and gives me the following mistake I don't understand.
