I want to change the value of the “reference” tag off a gauge in my ESP32 code.
The gauge:
var humidityData = [
{
domain: { x: [0, 1], y: [0, 1] },
value: 0,
title: { text: "Feuchtigkeit" },
type: "indicator",
mode: "gauge+number+delta",
delta: { reference: 69 },
gauge: {
axis: { range: [40, 103] },
steps: [
{ range: [10, 65], color: "red" },
{ range: [65, 68], color: "yellow" },
{ range: [68, 75], color: "lightgreen" },
{ range: [75, 78], color: "yellow" },
{ range: [78, 103], color: "red" },
],
},
},
];The code that should update the reference:
function updateGauge(temperature, humidity, humidity_soll) {
var temperature_update = {
value: temperature,
};
var humidity_update = {
value: humidity,
reference: humidity_soll,
};
Plotly.update(temperatureGaugeDiv, temperature_update);
Plotly.update(humidityGaugeDiv, humidity_update);
}But the reference is still the initial one. It is not updated by the handler with the new value from the json i handed over correctly.
Changing the “simple” value tag ist not problem. But the “reference” tag is not updated.
Any suggestions for me?
Its my first implementation of plotly.io so far.
So sorry for the noob question…
Kind regards
