der Browser läuft auf dem gleichen System wie iob.
Also die web.0 läuft, während dem flexcharts gar nicht gestartet werden kann (keine Konfiguration, kein start-Knopf). ich sehe nur:

Was heisst aktiv? Wie kann ich flexcharts aktivieren?
ich sehe folgende Meldungen:

Es heisst ja, der Pfad sei falsch.
Bei mir gibt es folgendes Verzeichnis:
C:\ioBroker\node_modules\iobroker.flexcharts
aber dort ist sowohl lib als auch www drin. Aber unter lib ist kein www.

allerdings gibt es unter www die Datei 404.html, die ist aber vom1.10.2024?!
Vielleicht ist da beim filepath das Problem. Da sind slashes und backslashes gemixt. (Habe Windows)
Hier noch das Verzeichnis von ...iobroker.flexcharts\www:

und da noch den Inhalt von echarts.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>ECharts</title>
<!-- Include the ECharts file you just downloaded -->
<script src="echarts.js"></script>
</head>
<body>
<!-- Prepare a DOM with a defined width and height for ECharts -->
<div id="main" ></div>
<script>
var jsopts = { solution: 42 };
var myChart = echarts.init(document.getElementById('main'),null,{
width: window.innerWidth-10,
height: window.innerHeight-20,
});
window.addEventListener('resize', function() {
myChart.resize({
width: window.innerWidth-10,
height: window.innerHeight-20,
});
});
myChart.setOption(jsopts);
</script>
</body>
</html>
