Good day!
My code doesn't display the chart.
I am trying to plot my json data into a google material line chart to output a chart like these:
here's my javascript code:
google.charts.load('current', {'packages': ['line', 'corechart', 'bar','controls', 'table']});
google.charts.setOnLoadCallback(drawChartCountry);
function drawChartCountry() {
var jsonData1 = $.ajax({
url: "analytics/country-sales.php",
dataType: "json",
async: false
}).responseText;
var data1 = new google.visualization.DataTable(jsonData1);
var options = {
title: 'Top 20 Countries with the highest sales',
pointSize: 5
};
var formatter_amount1 = new google.visualization.NumberFormat({prefix: 'HKD ', negativeColor: 'red', negativeParens: true});
// formatter_amount1.format(data1, 1);
var chart = new google.visualization.LineChart(document.getElementById('chart_div_country'));
chart.draw(data1, options);
}
and here's my json data
{"cols":[[[{"label":"Date","type":"string"},{"label":"TAIWAN","type":"string"},{"label":"HONG KONG","type":"string"},{"label":"JAPAN","type":"string"},{"label":"INDONESIA","type":"string"},{"label":"THAILAND","type":"string"},{"label":"UNITED STATES","type":"string"},{"label":"PHILIPPINES","type":"string"},{"label":"UNITED KINGDOM","type":"string"},{"label":"MALAYSIA","type":"string"},{"label":"AUSTRALIA","type":"string"},{"label":"SINGAPORE","type":"string"},{"label":"SPAIN","type":"string"},{"label":"SWEDEN","type":"string"},{"label":"GERMANY","type":"string"},{"label":"VIET NAM","type":"string"},{"label":"SOUTH KOREA","type":"string"},{"label":"NORWAY","type":"string"},{"label":"FRANCE","type":"string"},{"label":"CANADA","type":"string"},{"label":"NETHERLANDS","type":"string"}]]],"rows":[{"c":[{"v":"Date(2014,1,1)"},{"v":48876},{"v":3970},{"v":2505},{"v":1824},{"v":982},{"v":676},{"v":491},{"v":387},{"v":238},{"v":173},{"v":162},{"v":108},{"v":101},{"v":98},{"v":96},{"v":91},{"v":88},{"v":84},{"v":82},{"v":72}]}]}
here's the html code (removed some elements not related to this topic)
<head>

</div>
</div>
</body>
Can anyone help me please. Thank you.
any answer is highly appreciated.
first, the "cols" are wrapped in too many arrays
[[[]]] vs. []
{"cols":[[[{"label":"Date","type":"string"},...,{}]]],
should be...
{"cols":[{"label":"Date","type":"string"},...,{}],
next, the column type for the line series should be 'number'
and recommend 'date' for the first column
this...
"cols": [
{"label":"Date","type":"date"},
{"label":"TAIWAN","type":"number"},
{"label":"HONG KONG","type":"number"},
not this...
"cols": [
{"label":"Date","type":"string"},
{"label":"TAIWAN","type":"string"},
{"label":"HONG KONG","type":"string"},
also, if you want a Material line chart,
just need the 'line' package and...
google.charts.Line
the Core chart version is...
google.visualization.LineChart
and highly recommend not using async: false, use .done and .fail callbacks instead
see following working snippet, move code from .fail to .done to test locally...
google.charts.load("current", {
callback: drawChartCountry,
packages: ["line", "corechart"]
});
function drawChartCountry() {
$.ajax({
url: "analytics/country-sales.php",
dataType: "json"
}).done(function (jsonData) {
}).fail(function (jqXHR, textStatus) {
var jsonData = {

I am trying to change the color of "well" on mouseover but unable to do it. I have been trying with the following codes:
<script type="text/javascript">
function ChangeColor(well, highLight)
{
if (highLight)
{
well.style.backgroundColor = '#dcfac9';
}
}
</script>
PHP:
echo " <div class=\"well\" onmouseover=\"ChangeColor(this, true);\"\n";
echo " onmouseout=\"ChangeColor(this, false);\"> \n";
echo "something";
echo " </div>\n";
The above code is changing color nicely on mouseover but it is crossing the area of the "well". Please help to fix it.
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"/>
<div class="well">
<p>
This is a well content
</p>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<script>
$(".well").mouseenter(
function(){
$(this).css('background-color','red');
});
$(".well").mouseleave(
function(){
$(this).css('background-color','#f5f5f5');
});
</script>
Doing this through JavaScript seems like overkill. This can easily be done simply through the use of CSS:
.well:default
{
background-color: #ccc;
}
.well:hover
{
background-color: #000;
}
var getDefaultBg = $(".well").css("background");
$(".well").mouseover(function() {
$(this).css("background", "#000");
}). mouseout(function() {
$(this).css("background", getDefaultBg);
});
simply use this for your requirement.
That was the script I wanted:
<script>
$(document).ready(function(){
$(".well").mouseenter(function(){
$(this).css("background-color", "#efefef");
});
$(".well").mouseleave(function(){
$(this).css("background-color", "#f5f5f5");
});
});
</script>
I am having an issue with Google Charts. I have created the exact format it shows in the example inside a PHP vaiable

I have made this script that get's the month and the year from calendar.php and I would like when I click the link previous month to get the previous month but also when month number reach 1 make the year - 1. How can I do something like that?
<html>
<head></head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>
<script>
$(function() {
get_data();
});
function get_data(a, b) {
$.get('calendar.php', {
month: a, year: b
},
function(response) {
$el = $('<div></div>').attr('class', 'data').html(response);
$('#datas').prepend($el);
height = $el.height()+'px';
$el.css({'opacity': 0, 'display': 'block', 'height': '0px'}).animate({height: height }, 500, function() {
$(this).animate({opacity: 1}, 500);
})
});
}
</script>
<style>
#datas {
overflow: hidden;
}
.data {
display: none;
}
</style>
<body>
<a href="#" OnClick="get_data(9, 2012);" > Previous month</a>
<div id="datas">
</div>
</body>
</html>
I think you should use jQuery.ajax
$.ajax({
url: 'calendar.php',
success: function(data) {
// Parse your data and do all neccessery refreshing
}
});
in order get yerstaday you can use
var d = new Date(/* data that you get from calendar.php*/);
d.setDate(d.getDate() - 1);
