How to decrease google letters

Question

Hello, I would like to know how to customize the letters of Google Charts, I have a generated chart, however the names are big, so they do not appear all, someone knows a way to decrease the letters or else, put the fallen words?

Follows the code

     var options = {

            chart: {
                title: 'Relatorio Geral',
                subtitle: 'Quantidade de Operarios por função',
            },

            chartArea: { width: '100%', height: '50%' },
            annotations: {
                textStyle: {
                    fontName: 'Times-Roman',
                    fontSize: 18,
                    bold: true,
                    italic: true,
                    // The color of the text.
                    color: '#871b47',
                    // The color of the text outline.
                    auraColor: '#d799ae',
                    // The transparency of the text.
                    opacity: 0.8
                }
            }
    };

Answer 1

According to the documentation you can use textstyle. https://developers.google.com/chart/interactive/docs/gallery/scatterchart#Configuration_Options

var options = {
  annotations: {
    textStyle: {
      fontName: 'Times-Roman',
      fontSize: 18,
      bold: true,
      italic: true,
      // The color of the text.
      color: '#871b47',
      // The color of the text outline.
      auraColor: '#d799ae',
      // The transparency of the text.
      opacity: 0.8
    }
  }
};

For vertical text:

              hAxis: {
                   title: "",
                   slantedText: true,  /* Enable slantedText for horizontal axis */
                   slantedTextAngle: 90 /* Define slant Angle */
                   
              }
