    Syntax
    Example
    Create a histogram for every field of type Double
    // For more information on the chart CIM specification:
    // https://github.com/Esri/cim-spec/blob/main/docs/v3/CIMCharts.md

    var lyrDefHistogram = lyrHistogram.GetDefinition();
    
    // Get list names for fields of type Double
    var doubleFields = lyrHistogram.GetFieldDescriptions().Where(f => f.Type == FieldType.Double).Select(f => f.Name);
    
    // Create list that will contain all histograms
    var histograms = new List<CIMChart>();
    
    // Create histogram for each Double field
    foreach (var field in doubleFields)
