How I can get space between the bars of my chart?

Question

https://i.stack.imgur.com/TzY6q.png

I'm building this chart in a windows forms application using c# and I didn't find a way to separate the bars of the chart. As you can see in the images they are "glued". Anyone can help me with that? What I'm doing wrong? Please see the link to check my actual chart.

Thank you

my code:

    private void InitChart()
    {
        if (AvaliacaoFisica != null)
        {
            // Data arrays.
            string[] seriesArray = { "Ombros", "Peito", "Brç Dir", "Brç Esq", "Cintura", "Abs", "Anca", "Coxa Drt", "Coxa Esq" };//"Altura", "Peso", "Idade",
            double[] pointsArray = { 
                                     double.Parse(AvaliacaoFisica.PerOmbros.ToString(), System.Globalization.CultureInfo.InvariantCulture), double.Parse(AvaliacaoFisica.PerPeito.ToString(), System.Globalization.CultureInfo.InvariantCulture),  double.Parse(AvaliacaoFisica.PerBracoDir.ToString(), System.Globalization.CultureInfo.InvariantCulture),

                                   };//double.Parse(AvaliacaoFisica.Altura.ToString(), System.Globalization.CultureInfo.InvariantCulture) * 100, double.Parse(AvaliacaoFisica.Peso.ToString(), System.Globalization.CultureInfo.InvariantCulture), dcsDB.GetInt(AvaliacaoFisica.Idade),

            // Set palette.
            this.chart1.Palette = ChartColorPalette.Fire;   //Colors group for chart
