Google LineChart How to set default Point style in options?

[Georgess]

Instead of setting style for each point in data I want to set style only once in var options.

For example pointStyle: {shape-type: square,  stroke-width: 4, fill-color: 'transparent', stroke-color: 'red' }

How it can be done?

var options = {

          legend: 'none',
          hAxis: { minValue: 0, maxValue: 9 },
          curveType: 'function',
          pointSize: 7,
          dataOpacity: 0.8,
       
          pointStyle: {shape-type: square,  stroke-width: 4, fill-color: 'transparent', stroke-color: 'red' }
      
        };

function drawChart() {
      var data = google.visualization.arrayToDataTable
            ([['X', 'Y', {'type': 'string', 'role': 'style'}],
              [1, 3, null],
              [2, 2.5, null],
              [3, 3, null],
              [4, 4,  'point { size: 8; shape-type: circle; fill-color: orange;}'],

              [5, 4, 'point  {shape-type: square; size: 10; stroke-width: 2; fill-color: transparent; stroke-color: red;}'],

              [6, 3, 'point  { size: 18; shape-type: star; fill-color: #a52714; }'],
              [7, 2.5, null],
              [8, 3, null]
        ]);

Good idea, but we don't support a single default pointStyle option for all series.  You'll have to instead set the separate options for pointSize, pointShape, dataOpacity, colors, and lineWidth. Or for a particular series, you can use several slightly different options, e.g. 

 var options = {

    series: {

      0: { color: 'black', pointSize: 7, lineWidth: 4 }

    }

  }
