Adding a value indicator below a graph BLE

[TorstenKlf]

Hello,
it must be very simple. For my ESP32 Hall-Sensor I want to show the measured valut underneath the graph. Can anybody help, pease?

#include <phyphoxBle.h>

int AnalogPin=27;
float Messwert;
float Magnetfeld;

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;

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

//  graph.setChannel(1,2);

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