I'm new to echarts so please forgive me if this is stupid newbie request. I'm trying to rotate whole chart just like in this example of Vega Edge Bundling Example. On the right corner there is a tool and one option is also "rotate".
Example Image of Vega
I would like to do the same thing (rotate whole graph) in echarts but I can't find a way to do it. If it is possible to do it please let me know how I can do it. Thank you for any reply!
It's not perfect but I tried.
I use function to change startAngle,I don't know why the rotation is delayed.
var option = {
title: {
text: 'Referer of a Website',
subtext: 'Fake Data',
left: 'center'
},
tooltip: {
trigger: 'item'
},
legend: {
orient: 'vertical',
left: 'left'
},
series: [
{
name: 'Access From',
type: 'pie',
radius: '50%',
startAngle: 15,
data: [
{ value: 1048, name: 'Search Engine' },
{ value: 735, name: 'Direct' },
{ value: 580, name: 'Email' },
{ value: 484, name: 'Union Ads' },
{ value: 300, name: 'Video Ads' }
],
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
var myChart2 = echarts.init(document.getElementById('main2'));
myChart2.setOption(option);
function rotate() {
var Angle=document.getElementById("range").value;
myChart2.setOption({
series: [{
startAngle:Angle,
}]
});
};

I have a grid that has a grid in the detailInit and when I add a new row to the grid in the detailInit the detailInit collapses.
How can I stop it from collapsing when a new record is added? I have tried using e.preventDefault() on the button click event of adding a new row but that didn't work out.
You cannot prevent it from collapsing because every time you change something to the data it automatically rebinds and redraw the table.
What you can do however is to capture the rebinding, find the opened details and after the binding finish reopen them:

The CSV file is probably cached now in your browser, this causes Amcharts to immediately create the Chart. Unfortunately the div container doesn't exist yet. Either move your chart initialisation script tag below the chart div or wrap it in a DOMContentLoaded eventlistener or move the script to a separate file.
Option 1 move the script tag below the target div
<body>
<div id="chartdiv"></div>
<script type="text/javascript">
AmCharts.loadFile("https://s3-us-west-2.amazonaws.com/s.cdpn.io/t-160/22300.csv", {}, function (response) {
/**
* Parse CSV ....
*/
});
</script>
</body>
Option 2 wrap initialisation around DOMContentLoaded
document.addEventListener("DOMContentLoaded", function(event) {
AmCharts.loadFile("https://s3-us-west-2.amazonaws.com/s.cdpn.io/t-160/22300.csv", {}, function (response) {
/**
* Parse CSV ....
*/
});
});
I am trying to generate a bar graph using data from MYSQL through ajax by taking two input date fields from the user and returning the results using ajax.The problem is that when i select the date range, it doesn't show me anything.
I am new to Ajax as well, so any help will be appreciated.
Below is the code i have tried so far;

SOLVED! Use my code!
I just can't use Ajax to refresh my result in JustGage. I've checked another post on Stackoverflow but this does not work. Could you please tell me what I'm doing wrong with the last setInterval function.
Thanks!
