I'm using DotNet.HighChart in C # WebForms.

My chart currently looks like this:

        serieEspecial.Name = "Especial";
        serieRepAtivos.Name = "Rep. de Ativos";

        serieMassivos.Type = ChartTypes.Column;
        serieEspecial.Type = ChartTypes.Column;
        serieRepAtivos.Type = ChartTypes.Column;

        Series[] series = new Series[] { serieMassivos, serieEspecial, serieRepAtivos };

        Highcharts chart = new Highcharts("bar").SetTitle(new Title
            {
                Text = "Quantidade Projetos"
            }).SetXAxis(new XAxis
            {
                Categories =
                    new[]
                        {
                            "Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul", "Ago", "Set", "Out", "Nov", "Dez"
                        }
            })

    .SetSeries(series);

        return chart.ToHtmlString();
    }
