XPlot in a C# .NET Console App (not a jupyter notebook)

[CBrauer]

Hey, Great work on XPlot.

Any plans to support XPlot in a C# Console App (not a jupyter notebook)? I get a plot window, with the following code, but no data is drawn.

    using System;
    using System.Collections.Generic;
    using System.Diagnostics;
    using System.IO;
    using System.Linq;
    using Microsoft.ML;
    using Microsoft.ML.AutoML;
    using Microsoft.ML.Data;
    using Microsoft.ML.Featurizers;
    using Tensorflow;
    using XPlot.Plotly;

    namespace BottleRocketClassify {
        internal static class Program {
            public static class ModelBuilder {
                public static void Run() {
                    var mlContext = new MLContext(seed: 1);

                    var trainDataView = mlContext.Data.LoadFromTextFile<ModelInput>(
                        path: @"../../../data/train.csv",
                        hasHeader: true,
                        separatorChar: ',');

                    int numberOfRows = 1000;
                    var boxRatio = 
                        trainDataView.GetColumn<float>("BoxRatio").Take(numberOfRows).ToArray();

                    var data = boxRatio.Cast<float>();
                    var chart = new PlotlyChart();
                    Chart.Bar(data);
                    Chart.Show(chart);
                }
            }
        }
    }

Hi CBrauer, use of XPlot within C# console apps should certainly be supported. Rather than calling Chart.Show on your newly constructed PlotlyChart, please try the following instead:

Chart.Bar(data).Show();

As a minimal test, the following could be used:

using System.Linq;
using XPlot.Plotly;

namespace XPlotTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var data = Enumerable.Range(0,100).Select(v => v+.0);
            Chart.Bar(data).Show();
        }
    }
}

This is to replace Program.cs generated using:

dotnet new console -n XPlotTest
cd XPlotTest
dotnet add package XPlot.Plotly
dotnet add package FSharp.Core

All seems fine on my machine (TM)!

as a note i had to also install newtonsoft json, but other than that this worked perfectly!

Hey @malisimo , thx for the answer! Could you maybe provide a C# syntax example on how to draw a line chart, containing two data series?

var data = list1.Zip(list2, (a,b) => Tuple.Create(a,b)); Chart.Line<int,int>(data).Show();

This syntax only shows one line...
