Android: Highcharts werden nicht auftauchen? ⇐ Android

[Anonymous]

Ich versuche, ein Zeilendiagramm mehrerer Serien in Highcharts Android mit X-Achse mit Monaten (z. B. 'Jan', 'Feb') und den Werten auf y-Achse (AVG_IEX, PXIL VALUTS usw.) zu implementieren. Ich habe andere Diagramme mit ähnlichem Ansatz implementiert, aber dieses Diagramm wird nicht angezeigt. Ich habe versucht, statische Daten zu verwenden, auf denen die Tabelle zeigt, wann Code außerhalb des StringRequest -Umfangs geschrieben wird. Das Log -Ergebnis zeigt jedoch: < /p>

'Monpr'A3.58, 4,6, 7,95, 9,52, 6,81, 6,88, 5,5, 5,43, 5,87, 3,96, 4,8, 5,58]. /> Im Folgenden finden Sie den Code: < /p>
HIChartView monprchart = findViewById(R.id.monprchart);
HIOptions options = new HIOptions();

HIChart chart = new HIChart();
chart.setType("line"); // Use 'line' for step line chart
options.setChart(chart);

HITitle title = new HITitle();
title.setText("Volume (MW)");
HICSSObject style = new HICSSObject();
style.setFontSize("15px");
title.setStyle(style);
options.setTitle(title);

StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_MONPRCHART,
new Response.Listener() {
@Override
public void onResponse(String response) {

try {
JSONObject jsonObject = new JSONObject(response);
String success = jsonObject.getString("status");
final JSONArray jsonArray1 = jsonObject.getJSONArray("price_mmr");
// Log.v("Data_", String.valueOf(jsonArray1));
if (success.equals("true")) {

List block_time = new ArrayList();
List avg_iex_price = new ArrayList();
List avg_pxil_price = new ArrayList();
List avg_traders_price = new ArrayList();
List avg_ui_price = new ArrayList();

for (int i = 0; i < jsonArray1.length(); i++) {
JSONObject object1 = jsonArray1.getJSONObject(i);

block_time.add(object1.getString("block_time"));
avg_iex_price.add(parseNumber(object1.optString("avg_iex_price", "0")));
avg_pxil_price.add(parseNumber(object1.optString("avg_pxil_price", "0")));
avg_traders_price.add(parseNumber(object1.optString("avg_traders_price", "0")));
avg_ui_price.add(parseNumber(object1.optString("avg_ui_price", "0")));
}

// 3. X-Axis (e.g., categories or time)
HIXAxis xAxis = new HIXAxis();
xAxis.setCategories(new ArrayList(block_time)); // Example
options.setXAxis(new ArrayList(Collections.singletonList(xAxis)));

Log.d("MONPR",avg_iex_price.toString());

HIYAxis yAxis = new HIYAxis();
HITitle yTitle = new HITitle();
yTitle.setText("");
yAxis.setTitle(yTitle);
options.setYAxis(new ArrayList(Collections.singletonList(yAxis)));

// 5. Create multiple step line series
List seriesList = new ArrayList();

HILine series1 = new HILine();
series1.setName("Avg. IEX");
series1.setData(new ArrayList(avg_iex_price));
// series1.setStep("left");
series1.setColor(HIColor.initWithHexValue("007bff"));
seriesList.add(series1);

HILine series2 = new HILine();
series2.setName("Avg. PXIL");
series2.setData(new ArrayList(avg_pxil_price));
// series2.setStep("left");
series2.setColor(HIColor.initWithHexValue("28a745"));
seriesList.add(series2);

options.setSeries(new ArrayList(seriesList));

monprchart.setOptions(options);//monprchart chart id
monprchart.reload();
}
} catch (Exception e) {
e.printStackTrace();
}

}
}
