Deseja diferenciar os dados de uma única série e mostrá-los no gráfico em highcharts / highstock
Estou trabalhando no asp.net MVC 5 Referindo-me à minha pergunta, eu quero tirar a diferença entre cada dois pontos como este2-1 3-2 4-3 5-4 e assim por diante e depois colocá-los nos dados da minha série no gráfico
Abaixo está o código do meu controlador
//Getting data from DB to view in charts
SqlCommand Device_Id_command = new SqlCommand("Select Device_ID, Energy_kWh,Power_kW,Voltage_Phase_1,Data_Datetime,Voltage_Phase_2,Voltage_Phase_3,Current_Phase_1,Current_Phase_2,Current_Phase_3 from [ADS_Device_Data] where Device_Serial_Number=@serial_number AND Data_Datetime between'" + time.ToString(format) + "'AND'" + time2.ToString(format) + "'", con);
Device_Id_command.Parameters.AddWithValue("@serial_number", serial_number);
con.Open();
SqlDataReader reader = Device_Id_command.ExecuteReader();
//SqlDataReader reader_events = event_command.ExecuteReader();
while (reader.Read())
{
energy_kwh.Add(Convert.ToDouble(reader["Energy_kWh"]));
power_kw.Add(Convert.ToDouble(reader["Power_kW"]));
voltage_1.Add(Convert.ToDouble(reader["Voltage_Phase_1"]));
voltage_2.Add(Convert.ToDouble(reader["Voltage_Phase_2"]));
voltage_3.Add(Convert.ToDouble(reader["Voltage_Phase_3"]));
current_1.Add(Convert.ToDouble(reader["Current_Phase_1"]));
current_2.Add(Convert.ToDouble(reader["Current_Phase_2"]));
current_3.Add(Convert.ToDouble(reader["Current_Phase_3"]));
Meter_datetime.Add(sample_con.ConvertToUnixTimestamp(Convert.ToDateTime(reader["Data_Datetime"])));
device_id = Convert.ToInt32(reader["Device_ID"]);
}
con.Close();
Depois disso, coloquei todos os dados provenientes do leitor emViewData
ViewData["energy_kwh"] = energy_kwh;
ViewData["Meter_datetime"] = Meter_datetime;
ViewData["power_kw"] = power_kw;
ViewData["voltage_1"] = voltage_1;
ViewData["voltage_2"] = voltage_2;
ViewData["voltage_3"] = voltage_3;
ViewData["current_1"] = current_1;
ViewData["curr,ent_2"] = current_2;
ViewData["current_3"] = current_3;
Na minha navalha eu fiz o seguinte
// **************** Data arranging coming from controller *************
var myArrayX_kwh = [];
var myArrayY_kwh = [];
var myArrayY_power = [];
var myArrayY_voltage_1 = [];
var myArrayY_voltage_2 = [];
var myArrayY_voltage_3 = [];
var myArrayY_current_1 = [];
var myArrayY_current_2 = [];
var myArrayY_current_3 = [];
//var myArrayY_getData = [];
var arry_kwh = [];
var arry_power = [];
var arry_voltage_1 = [];
var arry_voltage_2 = [];
var arry_voltage_3 = [];
var arry_current_1 = [];
var arry_current_2 = [];
var arry_current_3 = [];
Depois disso eu adicionei 2 loops que empurram os valores dex ey eixo
@foreach (var st in ViewData["Meter_datetime"] as List<double?>)
{
@:myArrayX_kwh.push(@st);
}
@foreach (var st in ViewData["energy_kwh"] as List<double?>)
{
@:myArrayY_kwh.push(@st);
}
@foreach (var st in ViewData["power_kw"] as List<double?>)
{
@:myArrayY_power.push(@st);
}
@foreach (var st in ViewData["voltage_1"] as List<double?>)
{
@:myArrayY_voltage_1.push(@st);
}
@foreach (var st in ViewData["voltage_2"] as List<double?>)
{
@:myArrayY_voltage_2.push(@st);
}
@foreach (var st in ViewData["voltage_3"] as List<double?>)
{
@:myArrayY_voltage_3.push(@st);
}
@foreach (var st in ViewData["current_1"] as List<double?>)
{
@:myArrayY_current_1.push(@st);
}
@foreach (var st in ViewData["current_2"] as List<double?>)
{
@:myArrayY_current_2.push(@st);
}
@foreach (var st in ViewData["current_3"] as List<double?>)
{
@:myArrayY_current_3.push(@st);
}
for (var i = 0; i < myArrayX_kwh.length; i++) {
arry_kwh.push({ x: myArrayX_kwh[i], y: myArrayY_kwh[i], });
arry_power.push({ x: myArrayX_kwh[i], y: myArrayY_power[i], });
arry_voltage_1.push({ x: myArrayX_kwh[i], y: myArrayY_voltage_1[i], });
arry_voltage_2.push({ x: myArrayX_kwh[i], y: myArrayY_voltage_2[i], });
arry_voltage_3.push({ x: myArrayX_kwh[i], y: myArrayY_voltage_3[i], });
arry_current_1.push({ x: myArrayX_kwh[i], y: myArrayY_current_1[i], });
arry_current_2.push({ x: myArrayX_kwh[i], y: myArrayY_current_2[i], });
arry_current_3.push({ x: myArrayX_kwh[i], y: myArrayY_current_3[i], });
//getData.push({y: myArrayY_getData[i] });
}
Depois disso, eu inicializei meu gráfico
var chart1 = new Highcharts.Chart({

}
}
},
series:
[
{
name: 'Energy kWh',
color: 'green',
data: arry_kwh,
}
],
});
Nota Estou visualizando 4 gráficos diferentes na minha visualização única
Eu só quero fazer diferença paraarry_kwh somente não para todos os gráficos
Atualizar
Eu adicionei esse pedaço de código depois que eu coloquei esse valor da matriz em uma série separada
var arry_kwh_diff = [];
for (var j = 0; j < arry_kwh.length - 1; j++)
{
arry_kwh_diff[j] = { x: arry_kwh.x, y: arry_kwh[j + 1].y - arry_kwh[j].y };
}
arry_kwh_diff[j] = { x: arry_kwh.x, y: arry_kwh.y };
Adicionando a matriz no código do meu gráfico
series:
[
{
name: 'Energy kWh',
color: 'green',
data: arry_kwh,
},
{
type: 'spline',
name: 'Difference',
data: arry_kwh_diff
}
],
Está me mostrando a imagem abaixo
Não está me mostrando valores corretos também não existe spline
Depois de mudar
var arry_kwh_diff = [];
for (var j = 0; j < arry_kwh.length - 1; j++)
{
arry_kwh_diff.push({ x: arry_kwh[j].x, y: arry_kwh[j + 1].y - arry_kwh[j].y });
}
arry_kwh_diff[j] = { x: arry_kwh[j].x, y: arry_kwh[j].y };
Agora está me mostrando uma visão vazia
Qualquer ajuda seria muito apreciada
