Question

Set to show only the 100 and -100 grids ticks: [-100, 100], but the horizontal 0 (zero) grid appears. How to hide?
<table class="columns">
<tr>
<th>Linear Scale</th>
</tr>
<tr>
<td><div id="linear_div"></div></td>
</tr>
</table>
<script>
google.charts.load('current', {'packages':['corechart', 'line']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Population');
data.addRows([
[new Date(1400, 1, 1), -44],
[new Date(1500, 1, 1), 33],
[new Date(1600, 1, 1), 88],
[new Date(1700, 1, 1), 100],
[new Date(1750, 1, 1), 200],

var linearOptions = {
title: 'World Population Since 1400 A.D. in Linear Scale',
legend: 'none',
width: 450,
height: 500,
hAxis: {

},
vAxis: {

Answer 1

use following option to hide 0 (baseline)
baselineColor: 'transparent'
see following working snippet...
google.charts.load('current', {'packages':['corechart', 'line']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Population');
data.addRows([
[new Date(1400, 1, 1), -44],
[new Date(1500, 1, 1), 33],
[new Date(1600, 1, 1), 88],
[new Date(1700, 1, 1), 100],
[new Date(1750, 1, 1), 200]
]);
var linearOptions = {
baselineColor: 'transparent',
title: 'World Population Since 1400 A.D. in Linear Scale',
legend: 'none',
width: 450,
height: 500,
hAxis: {
title: 'Date'
},
vAxis: {
title: 'Population (millions)',
ticks: [-100, 100]
}
};
var linearChart = new google.visualization.LineChart(document.getElementById('linear_div'));
linearChart.draw(data, linearOptions);
}
