我的网站上有一个Google折线图,其中显示了学生在整个学年的学习成绩。我启用了鼠标滚轮缩放。
explorer: {
axis: 'horizontal',
maxZoomIn: 0.25,
maxZoomOut: 4
},
现在,我想为用户提供禁用按钮滚动的可能性。是否可以删除“浏览器”部分或仅禁用滚动浏览变量?
答案 0 :(得分:0)
当然,让我们开始将资源管理器选项移至单独的变量...
var options = {
pointSize: 4
};
var explorer = {
axis: 'horizontal',
maxZoomIn: 0.25,
maxZoomOut: 4
};
然后我们可以像这样启用资源管理器...
options.explorer = explorer;
要禁用...
options.explorer = null;
请紧记,无论何时更改选项,都需要重新绘制图表...
请参阅以下工作片段...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['x', 'y'],
[0, 0],
[1, 1],
[2, 2],
[3, 3],
[4, 4]
]);
var options = {
pointSize: 4
};
var explorer = {
axis: 'horizontal',
maxZoomIn: 0.25,
maxZoomOut: 4
};
$('#explorer-option').on('click', function () {
if ($('#explorer-label').html() === 'Enable') {
options.explorer = explorer;
drawChart();
$('#explorer-label').html('Disable');
$('#explorer-icon').removeClass('ui-icon-circle-check');
$('#explorer-icon').addClass('ui-icon-circle-close');
} else {
options.explorer = null;
drawChart();
$('#explorer-label').html('Enable');
$('#explorer-icon').removeClass('ui-icon-circle-close');
$('#explorer-icon').addClass('ui-icon-circle-check');
}
});
var container = document.getElementById('chart_div');
drawChart();
function drawChart() {
var chart = new google.visualization.LineChart(container);
chart.draw(data, options);
}
});
