Highcharts - how to display multiple graphs on one page using multiple xml files - javascript

Is there a way to list let's say 2 charts on the same page where each chart has its data xml file? What I'm doing is generating xml files from rrdtool and I would like to view all charts for the same device on one page.
Here's the code I have that works for one chart:
test.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script src="js/test.js" type="text/javascript"></script>
<script type="text/javascript">
$.ajax({
type: "GET",
url: "xml/test.xml",
dataType: "xml",
success: function(xml) {
var series = []
//define series
$(xml).find("entry").each(function() {
var seriesOptions = {
name: $(this).text(),
data: []
};
options.series.push(seriesOptions);
});
//populate with data
$(xml).find("row").each(function() {
var t = parseInt($(this).find("t").text()) * 1000
$(this).find("v").each(function(index) {
var v = parseFloat($(this).text())
v = v || null
if (v != null) {
options.series[index].data.push([t, v])
};
});
});
options.title.text = "CPU - Last 3 hours"
$.each(series, function(index) {
options.series.push(series[index]);
});
chart = new Highcharts.Chart(options);
}
})
</script>
</head>
<body>
<div id="cpu" style="width: 800px; height: 400px; margin: 0 auto; padding: 20px"></div>
</body>
</html>
test.js
Highcharts.setOptions({
global: {
useUTC: false
}
});
options = {
chart: {
renderTo: 'cpu',
type: 'area',
},
title: {
text: 'CPU'
},
subtitle: {
text: ''
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
hour: '%H. %M',
}
},
yAxis: {
title: {
text: 'Utilization %'
}
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%H:%M', this.x) + ': ' + Highcharts.numberFormat(this.y, 2) + ' %';
}
},
plotOptions: {
area: {
fillColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1},
stops: [
[0, Highcharts.getOptions().colors[1]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
lineWidth: 1,
marker: {
enabled: false
},
shadow: true,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: []
}
And XML file - test.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xport>
<meta>
<start>1396030800</start>
<step>300</step>

<row><t>1396041600</t><v>NaN</v></row>
</data>
</xport>


I encountered the same problem and just solved it!
Before the ready() function:
var chart;
var chart1;
$( document ).ready(function() {
your code....
I created two options, each options render to a different container
options = {
chart: {
renderTo: 'container',
type: 'area',
},
options2 = {
chart: {
renderTo: 'container2',
type: 'area',
},
and use the code below to add to different container:
chart = new Highcharts.Chart(options);
chart1 = new Highcharts.Chart(options2);
then in your html:
<div id="container">
<div id="container2">
Hope this brief explanation helps. Feel free to ask me if anything is not clear to you.
Cheers,

Highcharts Local CSV Issues

I am having issues creating my Highcharts graph out of my csv data. I have the following code that seems that it should work but it produces a blank graph on my server, I think it has something to do with the way that I'm pulling my data. I am using a ajax requests to pull from the csv file and plot the points. My csv is formatted like this.
0,0,0,12:45:37
5,26,130,12:45:37
1,28,28,12:45:42
4,35,140,12:45:47
1,32,32,12:45:52
3,16,48,12:45:57
1,29,29,12:46:02
1,25,25,12:46:07
5,16,80,12:46:12
4,35,140,12:46:17
5,25,125,12:46:22
4,37,148,12:46:27
With new points being added to the csv file every 30 seconds.
This is my code producing a blank graph.

Please help.

You need to put date as timestamp.
Since the csv date doesn't contain the day, I suggest put the current date (but check your requirements).
Try this (create a new date based on string in ISO 8601 format):
var date = new Date(new Date().toISOString().substr(0,10) + 'T' + items[3])

The JavaScript console is saying undefined function. When I put the highstock script above the exporting script, as in the jsfiddle you linked, it works fine.

The problem is that you refer to serie OHLC which is supported only in Highstock. So you need to attach highstock.js

Issue in multiple exporting for HighChart with scrollbar

I am facing an issue with exporting a column chart with scroll bar enabled which is not exporting a full chart after a scroll. It works for the first time, but when I scroll to the right or left and then when I export, the export is not happening completely.
Here is the sample.

How to resolve the issue?. If you see the pop-up dialog it is not displaying the same "export enabled" boolean value.

Adding min and minRange to your exporting.chartOptions.xAxis seems to yield positive results. This does require max to still be there, and seemingly it gives varying results if any of those three are missing.
For example (updated JSFiddle):
exporting:{
enabled: true,
sourceWidth: 960,
sourceHeight: 400,
chartOptions: {
xAxis: [{
categories: categories,
min: 0, // Added for fix
minRange: categories.length-1, // Added for fix
max: categories.length-1
}],
scrollbar:{
enabled: false
}
}
}
Hopefully this resolves your issue. As to why, I do not know.

how to create an array in javascript with values of a resultset

I want to pass the values of the resultset obtained from JSP to arrays in Javascript. Please help me.
JSP code that fetches data from database:
ResultSet resultset12 =
statement12.executeQuery("select * from(select HOST_NAME,INSTANCE_NAME,PID,PCPU, to_char(TIME, 'yyyy-mm-dd hh24:mi:ss') from ORA_CPU_STATUS where trunc(TIME)=trunc(sysdate) order by PCPU desc) where rownum<=10");
Following are the 2 resultsets, whose values I want to put in 2 arrays in javascript:
resultset12.getString(2) and resultset12.getString(4)
javascript array format that i want:
var input = [34.4, 62.5, 80.1, 70, 69.6, 69.5, 89.1, 68.4, 18, 17.3] and
categories = ['orcl1 ','orcl2 ','orcl3 ','orcl4 ','orcl5 ','orcl6 ','orcl7 ','orcl8 ','orcl9 ','orcl10 ']

My problem now is I am not able to pass the JSP Array to the javascript variable, as given below:
var input = JSON.parse("[" + <%out.print(csv);%> + "]"),
data = [],
categories = JSON.parse("[" + <%out.print(csvWithQuote);%> + "]");
The above javascript code should contain the values like below, then only my graph would work:
var input = [34.4, 62.5, 80.1, 70, 69.6, 69.5, 89.1, 68.4, 18, 17.3],
data = [],
categories = ['orcl1 ','orcl2 ','orcl3 ','orcl4 ','orcl5 ','orcl6 ','orcl7 ','orcl8 ','orcl9 ','orcl10 '];
#Chad, need your guidance on it.

How to pass JSP array to Javascript of highchart to generate a column chart

I am a novice in Highcharts, JSP and Javascript and need your input and suggestion on the issue, I have been struggling since 4-5 days. Please help me.
The issue is I am able to get the 2 output arrays from JSP that I need to pass in the highchart JS for generate a column graph.
[99, 90, 87, 82, 80, 77, 70, 65, 65, 60] and
['orcl2','orcl2','orcl2','orcl2','orcl1','orcl1','orcl3','orcl2','orcl3','orcl1']
But I am not able to pass the value to the JS to generate the column graph. Following is the entire code that I am using. Please suggest me where I am going wrong.
<%# page language="java" import="java.sql.*, java.io.*, java.util.Date, java.util.*,javax.servlet.*, java.text.SimpleDateFormat, java.util.Calendar " %>

Statement statement12 = connection.createStatement();
ResultSet resultset12 =
statement12.executeQuery("select * from(select HOST_NAME,INSTANCE_NAME,PID,PCPU, to_char(TIME, 'yyyy-mm-dd hh24:mi:ss') from ORA_CPU_STATUS where trunc(TIME)=trunc(sysdate) order by PCPU desc) where rownum<=10");

Thanks in Advance...

I'm not really sure where you're going with this code
String csv = list2.toString().replace("[", "").replace("]", "");
String csvWithQuote = list.toString().replace("[", "'").replace("]", "'").replace(", ", "','");
%>
var dincpu = '<%=csv%>';
var dinpcat = '<%=csvWithQuote%>';
var input = JSON.parse("[" + dincpu + "]"),
data = [],
categories = JSON.parse("[" + dinpcat + "]");
If you have your data in this format:
[99, 90, 87, 82, 80, 77, 70, 65, 65, 60] and
['orcl2','orcl2','orcl2','orcl2','orcl1','orcl1','orcl3','orcl2','orcl3','orcl1']
Why not do this (remove the 's and get rid of the JSON.parse)?
var dincpu = <%=csv%>;
var dinpcat = <%=csvWithQuote%>;
http://jsfiddle.net/VYLTW/

#Barbara,
it worked finally with
var dincpu = <%=csv%>;
var dinpcat = <%=csvWithQuote%>;
along with the fiddle that you gave http://jsfiddle.net/VYLTW/ .
I am putting the entire code in Answer that actually worked.

List<String> list2 = new ArrayList<String>();
while(resultset12.next())
{
String val = resultset12.getString(1);
list.add(val);
String val2 = resultset12.getString(2);
list2.add(val2);
}
String csv = list2.toString();
String csvWithQuote = list.toString().replace("[", "['").replace("]", "']").replace(", ", "','");

#Barbara,
1) If you see the latest code I have put all the JSP scriptlet "<% %>" at the top and then called the
var dincpu = <%=csv%>;
var dinpcat = <%=csvWithQuote%>;
After which I could see in view source of the webpage that the values are getting passed to the JS variables in the JS function.
2) Then put the same JS code that you have put in the fiddle.
3) I felt that the function $(document).ready(function() was causing problem which I removed.
And another important thing is that since I was putting all my code in a virtual linux box, there might be some hidden characters thats getting copied while I was coping from windows text editor (Editplus).
I found all those 3 things were responsible for the issue.
