LoadDataValue is a method that can be used to insert historic data to a point (more details on the ClearSCADA Database Schema).
Below there is an example on how to connect to a local server and use this method:

private void button9_Click(object sender, EventArgs e)
{
DBObject TestPoint;
Aggregate HistAgg;

Object[] args;
DateTime dt;
args = new Object[4];

using (Connection conn = new Connection("TestApp"))
{
// Connect to local server
SecureString passwd = new SecureString();
string strPassword = "adminexample";
foreach (char c in strPassword)
passwd.AppendChar(c);
passwd.MakeReadOnly();
conn.Connect("localhost");
conn.LogOn("AdminExample", passwd);

// Get the point
TestPoint = conn.GetObject("~Points.A1");
// If Historic is enabled for the point, insert historic data
if (TestPoint.Aggregates.TryGetValue("Historic", out HistAgg) == true)
{
args[0] = 0;
args[1] = 192;
dt = new DateTime(2019, 4, 3, 7, 21, 52);
args[2] = new System.DateTimeOffset(dt);
args[3] = 88;
HistAgg.InvokeMethod("LoadDataValue", args);
}
conn.LogOff();
conn.Disconnect();
}
}
