'GenericChart' does not contain a definition for 'WithTitle'

[giiyms]

I keep getting the error while using Plotly.NET.CSharp.

Error: (46,5): error CS1061: 'GenericChart' does not contain a definition for 'WithTitle' and no accessible extension method 'WithTitle' accepting a first argument of type 'GenericChart' could be found (are you missing a using directive or an assembly reference?)

It works when I call the Extension directly Plotly.NET.GenericChartExtensions.WithTitle(chart, "foobar") but chart.WithTitle("foobar") does not work.

I think its unsure whether to use F# or C# GenericChart. Any workarounds?

using Ext = Plotly.NET.GenericChartExtensions;
using StyleParam = Plotly.NET.StyleParam;
using Color = Plotly.NET.Color;
using Marker = Plotly.NET.TraceObjects.Marker;
using MarkerSymbol = Plotly.NET.StyleParam.MarkerSymbol;
using Mode = Plotly.NET.StyleParam.Mode;
using Colorscale = Plotly.NET.StyleParam.Colorscale;
using ColorKeyword = Plotly.NET.ColorKeyword;
using Title = Plotly.NET.Title;


var pcaLeadingTrailingChart = Chart.Scatter<double, double, string>(
    x: new[] { pc1Values[leadingIdx], pc1Values[trailingIdx] },
    y: new[] { pc2Values[leadingIdx], pc2Values[trailingIdx] },
    mode: Mode.Markers,
    MarkerColor: Color.fromColors(new[] { Color.fromKeyword(ColorKeyword.Red), Color.fromKeyword(ColorKeyword.Blue) }),
    Marker: Marker.init(
        Size: 10,
        Symbol: MarkerSymbol.Circle
    ),
    Name: "Leading/Trailing PCA"
);

Plotly.NET.GenericChartExtensions.WithTitle(pcaLeadingTrailingChart, "Leading/Trailing PCA");


// I think it is meant to work like this but it does not
var pcaLeadingTrailingChart = Chart.Scatter<double, double, string>(
    x: new[] { pc1Values[leadingIdx], pc1Values[trailingIdx] },
    y: new[] { pc2Values[leadingIdx], pc2Values[trailingIdx] },
    mode: Mode.Markers,
    MarkerColor: Color.fromColors(new[] { Color.fromKeyword(ColorKeyword.Red), Color.fromKeyword(ColorKeyword.Blue) }),
    Marker: Marker.init(
        Size: 10,
        Symbol: MarkerSymbol.Circle
    ),
    Name: "Leading/Trailing PCA"
).WithTitle("Leading/Trailing PCA");

Here is a simple VsCode Polyglot ipynb example

#!csharp

#i "nuget:https://api.nuget.org/v3/index.json"
// #r "nuget: Plotly.NET"
#r "nuget: Plotly.NET.Interactive"
#r "nuget: Plotly.NET.CSharp"

// Import the necessary namespaces
using Plotly.NET.CSharp;
using System;
using System.Linq;


// Create sample data
var x = Enumerable.Range(0, 10).Select(i => i).ToArray();
var y = x.Select(i => Math.Sin(i * 0.5)).ToArray();

// Create a line chart
var lineChart = Chart.Line<int, double, string>(x, y).WithTitle("Test");

The call is ambiguous between the following methods or properties: 'Plotly.NET.CSharp.GenericChartExtensions.WithTraceInfo(Plotly.NET.GenericChart, Plotly.NET.CSharp.Optional<string>, Plotly.NET.CSharp.Optional<Plotly.NET.StyleParam.Visible>, Plotly.NET.CSharp.Optional<bool>, Plotly.NET.CSharp.Optional<int>, Plotly.NET.CSharp.Optional<string>, Plotly.NET.CSharp.Optional<Plotly.NET.Title>)' and 'Plotly.NET.GenericChartExtensions.WithTraceInfo(Plotly.NET.GenericChart, Microsoft.FSharp.Core.FSharpOption<string>, Microsoft.FSharp.Core.FSharpOption<Plotly.NET.StyleParam.Visible>, Microsoft.FSharp.Core.FSharpOption<bool>, Microsoft.FSharp.Core.FSharpOption<int>, Microsoft.FSharp.Core.FSharpOption<string>, Microsoft.FSharp.Core.FSharpOption<Plotly.NET.Title>)'

How do you stop this also?

I think this might be due to using both Plotly.NET.CSharp and base plotly.net extensions at the same time. In future versions i want to be completely rid of the extension methods in the core lib, but it is not there yet. I guess for your use case you must decide to call one of the library methods with fully qualified namespace prefixes, and only open the other.
