Line chart Legend (1 reply)

user1247306 — Wed, 09 May 2012 08:44:49 -0500

I like the feature of being able to disable a line by clicking on its legend icon, but is there a way to update that icon to show that the line has been disabled? It's hard to tell when you're looking at 10+ lines which ones have been disabled.

Thanks

Bar Charts: Display only integer values for Y axis (1 reply)

user1180336 — Fri, 04 May 2012 09:34:32 -0500

All;
I've looked through the JS Charts user guide, but I'm not seeing the option I need. I have a bar chart whose Y values are integers, but the bar chart is getting displayed with the grid values as floats. For example, 0.5, 1.0, 1.5, 2.0, etc. which don't make sense for this particular chart. I need to display only integer values. Can anyone tell me what option I need to use to accomplish this?
Thanks;
Frank

Hello;
I just purchased a non-commercial license for JSCharts. However, when I used the domain key in an example like this:

var myChart = new JSChart('graph', 'bar', 'XXXXXXXXXXXXXX');

The watermark still appeared. Is there something else that I till need to do?
Thanks;

max number of x points (no replies)

user1221941 — Sun, 15 Apr 2012 03:32:13 -0500

Hi,

When putting ~300 x values (with tool-tip for each point) on the graph it takes a lot of time for the draw function. Is it correct? Does 300 is too much?

Thanks in advance

setShowXValues for string x values (no replies)

user1221941 — Sun, 15 Apr 2012 03:15:23 -0500

Hi All,
I use:
var myData = new Array([4,0],[5,0],[6,0],[7,0],[8,0],[9,2],[10,0],[11,0]);
var sessionsChart = new JSChart('graph', 'line');
sessionsChart.setDataArray(myData);
sessionsChart.setShowXValues(false);
sessionsChart.draw();

and everything work fine, no x values are shown. However if I use:

var myData = new Array(['4',0],['5',0],['6',0],['7',0],['8',0],['9',2],['10',0],['11',0]);
var sessionsChart = new JSChart('graph', 'line');
sessionsChart.setDataArray(myData);
sessionsChart.setShowXValues(false);
sessionsChart.draw();

all the X values are shown. Does setShowXValues(false) work only for numbers? I need it for strings since my values are 11-04, 12-04, 13-04... format and I don't want to show all of them.

Thanks in advance

graph killing internet explorer? (1 reply)

user1140836 — Sat, 24 Mar 2012 20:42:33 -0500

HOLY EMOTIOCONS??!?!?

I was looking up and down my php script... WHY WHY doesn't it work in IE, works fine in chrome/firefox...
I had to cut and paste each section of code to find out where its happening.

myChart.draw();

kills internet explorer.

Report

Loading chart...

$graph_str="['Wednesday', 6], ['Thursday', 0], ['Friday', 5], ['Saturday', 6], ['Sunday', 0], ['Monday', 2], ['Tuesday', 6]"
$high_call=6

I can browse the example graphs on the jschart website no problem, so it has to be something in this code. But what?

Any help? Any Idea why the graph is killing internet explorer?

Thanks
Nick

Using JSON object/string directly to create chart (no replies)

user1180396 — Tue, 13 Mar 2012 14:17:34 -0500

I am just getting my feet wet with JSCharts and things are going well except for one point. I can't find a way to pass a JSON object/string directly to create a chart.

The setDataJSON function can be used to have JSCharts contact the server itself which gets me the data I need but this is a blocking action, so the script stops dead while waiting for the server to respond. I want to do other things while the request is running. Additionally I want to use part of the returned JSON for other things besides the chart, but the way things are now I would need to make two separate requests to the server - I am working with mobile networks so this is something I really want to avoid.

Here is an example of what I would like to do:

function loadChart() {
    $.get("getChart.php",
        function(data) {
            var jso = $.parseJSON(data);
            drawChart(jso.chartData);
            processOtherStuff(jso.otherData)
        }
    );
    doSomethingWhileRequestInProgress();
}

function drawChart(jso) {
    var myChart = new JSChart('chartcontainer', 'line');
    myChart.setDataJSONObject(jso);
    myChart.draw();
}

I am kinda surprised this is not available because with no http necessary it's actually less work for the JSChart creators to make than the existing setJSONData function is :)

Dynamic JSON data (or XML) (1 reply)

user1046476 — Fri, 27 Jan 2012 14:53:02 -0600

I'm trying to load dynamic data to JSCharts. To do so, I have an ASP.NET HttpHandler on my server that returns JSON formatted data, I then set the setJSONData method to point to the URL of my HTtpHandler. Will that work with JSCharts? If not how do I handle dynamic data with JSCharts? Seems like it should be able to do so. Thanks!

Script Error when mousing over plot-points (1 reply)

user543666 — Mon, 30 Jan 2012 07:40:14 -0600

Hi,

I'm experiencing a problem with the charting controls (all browsers) whereby, if the mouse is moved over one or more plot-points (with the circle around them) whilst the chart is drawing, I get a script error. (this doesn't always happen but the error is always the same). Something along the lines of accessing a property when it's not ready.

It happens more in old browsers such as IE 7 and 8, but, it does happen in modern ones too.

Any ideas?

Cheers

setArea and callback on Bar chart in IE (no replies)

user1046476 — Wed, 07 Dec 2011 07:47:35 -0600

I am attempting to implement a bar chart with clickable bar areas to create a drill-down effect. I was able to get it to work using the setArea(unit, callback) method...however, it does not work in IE (surprise, surprise). It works perfectly in Firefox, and works in Chrome and Safari. I'm not getting any error messages in IE...just nothing happens when I click the bar. Here's a code sample of what I'm doing:

var myData = new Array(['Friend 1', 8], ['Friend 2', 5], ['Friend 3', 20]);
var myChart = new JSChart('chartcontainer', 'bar');
myChart.setDataArray(myData);
myChart.setArea('Friend 1', function() {
    goToUnit(8);
});

function goToUnit(unit) {
    alert(unit);
}

Any ideas on why that wouldn't work in IE? Thanks!

Loading XML as a string (no replies)

user1009676 — Mon, 05 Dec 2011 04:19:13 -0600

Hello,

I am currently evaluating jscharts for our charts rendering (prior to buy it) and I have difficulties loading xml as a string. The xml is available in my view as a string that i have to manipulate and then output to jscharts.

I saw the method setDataXml() and in particular the bool option to set to true when we want to load the xml as a string. But I Constantly have "Unexpected token ILLEGAL". To understand my problem, imagine you have to load xml as a string and that this xml has simple and double quotes in it.

Any idea ?
Thank you in advance.

Empty data points on a line chart (1 reply)

user902811 — Mon, 27 Feb 2012 10:39:50 -0600

I cannot seem to find this in the how-to's, but is there a means to have empty data points in a line chart? As in, a physical break on the line that does not appear?
As I'm thinking of this, would I just make the color of those data points transparent as a workaround?
EDIT: there does not seem to be a means to change the data points colors.

thanks!

JSChart: No data loaded using json (1 reply)

user969261 — Tue, 18 Oct 2011 06:01:55 -0500

Hi,

I tried many thing but I can't figure out what's wrong with my code.

The JS is from the example:

and the page /statistiques/ajax/statuts returns :

{
    "JSChart": {
        "datasets": {
            "type": "pie",
            "data": [
                {
                    "unit": "0",
                    "value": "0"
                },
                {
                    "unit": "1",
                    "value": "6088"
                },
                {
                    "unit": "2",
                    "value": "17"
                },
                {
                    "unit": "3",
                    "value": "4"
                },
                {
                    "unit": "4",
                    "value": "0"
                },
                {
                    "unit": "5",
                    "value": "0"
                },
                {
                    "unit": "6",
                    "value": "1"
                },
                {
                    "unit": "7",
                    "value": "7"
                },
                {
                    "unit": "8",
                    "value": "6"
                },
                {
                    "unit": "9",
                    "value": "66"
                },
                {
                    "unit": "10",
                    "value": "0"
                }
            ]
        }
    }
}

Which is valid according to [jsonlint.com] (the header even says Content-Type:application/json) and respects your schema as far as I know.

Any ideas of what could be wrong?, Why I get the message : JSChart: No data loaded?

Thanks!

Pie direction and angle offset (no replies)

Feature suggestion:

[*] set the angle for first item; i see now it's 0
[*] set direction; i see now it's clockwise. Not exactly needed if first feature is added; we could just reverse our data set and adjust initial angle

comma at the end of myData array causing error (no replies)

user834421 — Mon, 18 Jul 2011 14:54:41 -0500

I have created a list of possible chart items that are extracting values from the wordpress database. When I create the jscharts code to display the various items within the chart, all goes well until the last conditional. Because the myVar Array ends in a comma the chart does not render. I have tried different types of trimming the last character from the array that I found on google, but none seem to work.

Here is a clip of the conditional code I am using for the myData variable:

var myData = new Array(
	
	 
	
);

Any help is appreciated, Thanks.
