I'm sorry but unfortunately what you want is not possible.

Line chart Legend

user1247306 — Fri, 04 May 2012 18:06:16 -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

Re: Bar Charts: Display only integer values for Y axis

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

Frank,
Make sure that the number of values used on Y axis is the same as the interval you are using for Y axis.
If you want to have 10 values displayed, make sure that the end interval is between 0 and 9.
eg myChart.setAxisValuesNumberY(10)
myChart.setIntervalEndY(9)

Bar Charts: Display only integer values for Y axis

user1180336 — Mon, 30 Apr 2012 11:14:41 -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

Watermark still appears even with license

user1180336 — Tue, 24 Apr 2012 09:32:15 -0500

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;

Re: is there possible to purchase developer licence of js chart

Parameters in callback function

user1064991 — Mon, 16 Apr 2012 16:49:15 -0500

Hello, I have one problem. I use linechart with tooltips. I want to set myChart.setTooltip([15], function(){alert('callback');}); And in the function I want to show, on which tooltip user click. I want to set parameters of position linechart, but I dont know, how to do it.
Please help!.
Thank you a lot for your response.

max number of x points

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

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

Re: graph killing internet explorer?

graph killing internet explorer?

user1140836 — Sat, 24 Mar 2012 20:40:30 -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

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 :)

I am looking for the same thing- a way to define an 'undefined' value that will not display on a line graph. Example would be a stock price plotted over dates should not display a line for weekend/holidays.

Multiple Data Bar Charts Error

user607376 — Fri, 10 Feb 2012 11:46:33 -0600

Hi,
in addition to having conducted several tests with my script and also using your sample code, still get the following error: JSChart: Input data in wrong format for selected chart type.

Any suggestions to get the graph?

Re: Flag color match line color

kneo — Wed, 08 Feb 2012 09:08:43 -0600

You should use setFlagColor and setFlagFillColor methods for setting the color of your tooltip flags.

Re: Dynamic JSON data (or XML)

user1098421 — Fri, 27 Jan 2012 14:53:02 -0600

I did something like this but with XML.

Are you using MVC or ASP.NET webforms?

I just passed a HtmlString to a partial page containing off of my charts and popped that into the js

ex:
myChart.setDataXML("@Model.xmlString", true);

Hope that points you in the right direction.

Dynamic JSON data (or XML)

user1046476 — Mon, 12 Dec 2011 11:18:25 -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

user543666 — Wed, 07 Dec 2011 09:41:48 -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

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

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.

Re: Chart data auto refresh (ajax)

user993421 — Fri, 11 Nov 2011 09:22:23 -0600

Hi. I have the same question. Among several charts the user can choose to reload a single chart. How to do that, without resending the whole page?

resize

user990121 — Thu, 03 Nov 2011 00:37:43 -0500

Each time I call resize(x, y) to resize a JSChart, the chart's legend entries are duplicated. The resized chart otherwise looks fine but the growing legend is a problem. How can this behavior be avoided?
