How can you force Google Charts vAxes render?

wish of those help you can use the chartArea config code to ensure there is enough room on either side of the chart.
by default, the chart will follow the size of the container,
code :
chartArea: {
  top: 32,         // leave room on top for legend
  left: 60,        // for axis index 0
  right: 60,       // for axis index 1
  bottom: 32,      // for x-axis
  height: '100%',  // stretch height
  width: '100%',   // stretch width
},
height: '100%',    // ensure fills height of container
width: '100%',     // fills width of container
google.charts.load('current', {
  packages: ['corechart']
}).then(function () {
  var data = new google.visualization.DataTable({"cols":[{"label":"Date","type":"string"},{"label":"To Audit","type":"number"},{"label":"Open","type":"number"},{"label":"Closed","type":"number"}],"rows":[{"c":[{"v":"05/07/2018"},{"v":437},{"v":0},{"v":8}]},{"c":[{"v":"12/07/2018"},{"v":419},{"v":0},{"v":21}]},{"c":[{"v":"19/07/2018"},{"v":401},{"v":56},{"v":36}]},{"c":[{"v":"26/07/2018"},{"v":385},{"v":0},{"v":20}]},{"c":[{"v":"02/08/2018"},{"v":369},{"v":0},{"v":12}]},{"c":[{"v":"09/08/2018"},{"v":357},{"v":0},{"v":25}]},{"c":[{"v":"16/08/2018"},{"v":348},{"v":0},{"v":18}]},{"c":[{"v":"23/08/2018"},{"v":336},{"v":0},{"v":14}]},{"c":[{"v":"30/08/2018"},{"v":316},{"v":0},{"v":13}]}]});

  var options = {
    chartArea: {
      top: 32,         // leave room on top for legend
      left: 60,        // for axis index 0
      right: 60,       // for axis index 1
      bottom: 32,      // for x-axis
      height: '100%',  // stretch height
      width: '100%',   // stretch width
    },
    height: '100%',    // ensure fills height of container
    width: '100%',     // fills width of container

    hAxis: {showTextEvery: 5},
    vAxes: {
      0: {
        textPosition: 'out',
        viewWindowMode:'pretty',
        viewWindow: {min: 0},
        gridlines: {color: 'transparent'},
      },
      1: {
        textPosition: 'out',
        viewWindow: {min: 0},
        gridlines: {color: 'transparent'}
      },
    },
    seriesType: 'bars',
    series: {
      0: {targetAxisIndex:0, type: 'line'},
      1: {targetAxisIndex:1},
      2: {targetAxisIndex:1},
    }
  };

  var chart = new google.visualization.ComboChart(document.getElementById('chart_div1'));
  chart.draw(data, options);
  window.addEventListener('resize', function () {
    chart.draw(data, options);
  });
});

Google Charts - Failing to render a Row


By : HAL
Date : March 29 2020, 07:55 AM
Hope this helps The AreaChart appears not to draw anything if a data point doesn't have any values in the data points next to it. With nulls (or the edge of the graph) on both sides of any data point, the area would be of width 0. I'd say this is a bug with the chart API (it should really draw an area of width 1 in this case), which you may want to file here.
In the meantime, you may want to use a different chart type. Would a scatter plot be appropriate? It would have the advantage of not showing a potentially misleading line between data points. For example, in the current plot the plotted line may not match the real shape of the data, since your data is sparse. Say there was a spike and then a drop in the blue data between 2001 and 2003- the area chart type appears to tell a different story (a straight slope), while a scatter plot would not tell any false stories between the data you do have.

Moving vAxes - Google Chart

I wish this help you sure, it's possible, the chart is drawn using svg,
once the chart's 'ready' event fires,
code :
google.charts.load('current', {
  packages: ['corechart']
}).then(function () {
  var data = google.visualization.arrayToDataTable([
    ['x', 'y0', 'y1', 'y2', 'y3'],
    ['A', 15, 30, 65, 100],
    ['B', 12, 32, 67, 101],
    ['C', 14, 32, 67, 101],
    ['D', 18, 33, 68, 110],
    ['E', 17, 33, 68, 110],
    ['F', 17, 45, 70, 112],
    ['G', 18, 46, 71, 113],
    ['H', 22, 47, 72, 110],
    ['I', 24, 47, 72, 112],
    ['J', 20, 47, 72, 105],
    ['K', 17, 45, 70, 105],
    ['L', 17, 33, 68, 104],
    ['M', 16, 33, 68, 105],
    ['N', 15, 32, 67, 103]
  ]);

  var container = document.getElementById('chart_div');
  var chart = new google.visualization.LineChart(container);

  google.visualization.events.addListener(chart, 'ready', function () {
    var chartLayout = chart.getChartLayoutInterface();
    var chartBounds = chartLayout.getChartAreaBoundingBox();
    var labelBounds;
    var labelGap;
    var labelIndex = -1;
    var labelWidth;
    var xCoord;

    var labels = container.getElementsByTagName('text');
    Array.prototype.forEach.call(labels, function(label) {
      // move axis labels
      if ((label.getAttribute('text-anchor') === 'start') && (label.getAttribute('fill') === '#ff0000')) {
        labelIndex++;
        labelBounds = chartLayout.getBoundingBox('vAxis#1#label#' + labelIndex);
        labelWidth = labelBounds.width;
        labelGap = chartBounds.left - parseFloat(label.getAttribute('x'));
        xCoord = chartBounds.left + chartBounds.width + labelGap - labelWidth;
        label.setAttribute('x', xCoord);
      }

      // move axis title
      if ((label.getAttribute('text-anchor') === 'middle') && (label.textContent === 'var1')) {
        labelBounds = chartLayout.getBoundingBox('vAxis#1#title');
        labelWidth = labelBounds.width;
        labelGap = chartBounds.left - parseFloat(label.getAttribute('x'));
        xCoord = chartBounds.left + chartBounds.width + labelGap + labelWidth;
        var rotate = 'rotate(-90 ' + xCoord + ' ' + label.getAttribute('y') + ')';
        label.setAttribute('x', xCoord);
        label.setAttribute('transform', rotate);
      }
    });
  });

  chart.draw(data, {
    chartArea: {
      right: 136
    },
    series: {
      0: {targetAxisIndex: 0},
      1: {targetAxisIndex: 1},
      2: {targetAxisIndex: 2},
      3: {targetAxisIndex: 3}
    },

Google Charts haxis label render


By : user1859447
Date : March 29 2020, 07:55 AM
To fix this issue to show specific axis labels, use config option --> hAxis.ticks
ticks takes an array of values, each value will be shown as a label.
code :
hAxis: {
  ticks: [new Date(2018, 0, 1), new Date(2018, 1, 1), new Date(2018, 2, 1), ...]
}
hAxis: {
  ticks: [{v: new Date(2018, 0, 1), f: '01/01/2018'}, {v: new Date(2018, 1, 1), f: '02/01/2018'}, ...]
}
google.charts.load('current', {
  callback: function () {
    drawChart();
    window.addEventListener('resize', drawChart, false);
  },
  packages:['corechart']
});

function drawChart() {
  var datePattern = 'MM/dd/yyyy';
  var formatDate = new google.visualization.DateFormat({
    pattern: datePattern
  });

  var dataTable = new google.visualization.DataTable();
  dataTable.addColumn('date', 'X');
  dataTable.addColumn('number', 'Value');

  var oneDay = (1000 * 60 * 60 * 24);
  var startDate = new Date(2018, 0, 1);
  var endDate = new Date(2018, 9, 0);
  var ticksAxisH = [];
  for (var i = startDate.getTime(); i <= endDate.getTime(); i = i + oneDay) {
    // set x value
    var rowDate = new Date(i);
    var xValue = {
      v: rowDate,
      f: formatDate.formatValue(rowDate)
    };

    // add tick at beginning of each month
    if (rowDate.getDate() === 1) {
      ticksAxisH.push(xValue);
    }

    // set y value (y = 2x + 8)
    var yValue = (2 * ((i - startDate.getTime()) / oneDay) + 8);

    // add data row
    dataTable.addRow([
      xValue,
      yValue
    ]);
  }

  var container = document.getElementById('chart_div');
  var chart = new google.visualization.LineChart(container);
  chart.draw(dataTable, {
    chartArea: {
      height: '100%',
      width: '100%',
      top: 32,
      left: 48,
      right: 18,
      bottom: 32
    },
    hAxis: {
      ticks: ticksAxisH
    },
    height: 288,
    legend: {
      position: 'top'
    },
    width: '100%'
  });
}
