Axiom Scripting Methods

Is there an example on how to properly use IDataprovider methods like GetRawData? The scripting documentation has some examples but not any showcasing this.

    Here's an example of using DataProvider.GetRawData :

    using AxiomCore2.Client;
    using AxiomCore2.ControlProperties;
    using AxiomCore2.Controls;
    using AxiomCore2.Data;
    using AxiomCore2.Events;
    using AxiomCore2.Legacy;
    using AxiomCore2.Log;
    using AxiomCore2.Managers;
    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Collections;
    using System.Drawing;
    
    namespace AxiomScript
    {
        public partial class ScreenScript : IDisposable
        {
            // axiom references
            public ControlApplication Application { get; } = ControlApplication.Instance;
            public ControlFactoryManager ControlFactory { get; } = ControlFactoryManager.Instance;
            public IDataProvider DataProvider { get; } = DataProviderManager.CreateInstance();
            public ILog Log { get; } = ClientLog.UserScript;
            public NavigationManager Navigation { get; } = NavigationManager.Instance;
            public ControlScreen Screen => _screen;
    
            // EventTimer setup from documentation example https://axiomscripting.canarylabs.com/22.3/html/8675300e-3c1c-42c5-8590-9e4d4e9d7627.htm
            private EventTimer _timer = null;
            private int _initialTime = Convert.ToInt32(TimeSpan.FromSeconds(1).TotalMilliseconds);
            private int _interval = Convert.ToInt32(TimeSpan.FromSeconds(5).TotalMilliseconds);
    
            public void OnScreenVisible()
            {
                // check if Label1 exists, and create it if it doesn't already
                if(!Screen.ScreenControls.ContainsKey("Label1")){
                    var label1 = ControlFactory.CreateControl(ControlKind.Label, "Label1");
                    Screen.Children.Add(label1);
                }
                if (_timer == null)
                {
                    // initialize timer
                    _timer = new EventTimer(
                        callback: TimerCallback,
                        dueTime: _initialTime,
                        period: _interval);
                }
                else
                {
                    // reset timer
                    _timer.Change(
                        dueTime: _initialTime,
                        period: _interval);
                }
            }
    
            public void OnScreenInvisible()
            {
                if (_timer != null)
                {
                    // pause timer
                    _timer.Change(
                        dueTime: EventTimer.Infinite,
                        period: EventTimer.Infinite);
                }
            }
    
            public void Dispose()
            {
            }
    
            private void TimerCallback(EventTimer timer, object userData)
            {
                // update Label1 with CPU Usage tag data
                if(Screen.ScreenControls.ContainsKey("Label1")){
    
                    var label1 = (ControlLabel)Screen.ScreenControls["Label1"];
    
                    // use DataProvider to get raw data from a specific time period
                    var result = DataProvider.GetRawData("localhost.{Diagnostics}.Sys.CPU Usage Total",DateTime.Now.AddSeconds(-1),DateTime.Now,1,false);
    
                    Log.Info($"Got {result.Values.Count().ToString()} tag value(s)");
    
                    // loop through each TVQ in result
                    foreach(var tvq in result.Values){
                        Log.Info(tvq.ToString());
                    }
    
                    // in this example we are only using the first TVQ in the result
                    var firstTvq = result.Values.FirstOrDefault();
                    if(firstTvq != null){
                        var stringValue = firstTvq.Value.ToString();
                        label1.Text = stringValue;
                    }
                }
            }
        }
    }
