您好，我在下面尝试动态实现条形图。但是它没有给出任何错误。图数据未显示。 X轴标签和y标签从Api动态显示。 result_list是名为
的模型类的列表private ArrayList<MyTaskModel> outcome_list;
“没有可用的图表数据”这是我通过以下代码得到的输出。
if (name.equals("cf_1015")) {
outcome = String.valueOf(values);
}
}
}
PreferenceManagerMyTask.getInstance(requireContext()).setMultipleDataOutcome(scheduleDate,outcome);
}
MyTaskModel outcomeModel = new MyTaskModel(scheduleDate,outcome);
outcome_list.add(outcomeModel);
// Log.d("outcomeModel",outcome);
if(outcome.equals("Order Closed")){
OrderClosed= outcomeModel.getOutcome();
Log.d("Order Closed", OrderClosed);
Count_OrderClosed = Collections.frequency(outcome_list, "Order Closed");
Log.d("Count Order Closed", String.valueOf(Count_OrderClosed));
}else if(outcome.equals("Follow-up")){
Followup= outcomeModel.getOutcome();
Log.d("Followup", Followup);
Count_Followup = Collections.frequency(outcome_list, "Follow-up");
Log.d("Count_Followup", String.valueOf(Count_Followup));
}else if(outcome.equals("Interested")){
Interested= outcomeModel.getOutcome();
Log.d("Interested", Interested);
Count_Interested1 = Collections.frequency(outcome_list, "Interested");
Log.d("Count_Interested1", String.valueOf(Count_Interested1));
