Hi I am looking for a jQuery candlestock chart, if someone is able to help, that would be great, it would be great if JSCharts would do this?

how to get myData populated dynamically..can somebody explain me with a simple example maybe employee or salary stuff..

Empty String Passed to GetElementbyId() (1 reply)

KathrynAsha — Tue, 20 Apr 2010 08:37:35 -0500

Hi Guys,

I love the JSCharts component but i cannot seem to track down a warning being issued whenever i display a chart. The chart displays fine and has all the data in it as well as styling but it keeps bringing up the following 2 warnings per chart.draw().

"Warning: Empty string passed to getElementById()."
"Warning: Empty string passed to getElementById()."

I am using FF3.5.1 and here is the creation code

var myChart_Prices = new JSChart('id_TRADE_Chart_1', 'line');
myChart_Prices.setDataArray(Chart_Price_HIG_Array,'Highest Price');
myChart_Prices.setDataArray(Chart_Price_LOW_Array,'Lowest Price');
myChart_Prices.setDataArray(Chart_Price_AVG_Array,'Average Price');
myChart_Prices.setSize(759, 223);
myChart_Prices.setAxisValuesNumberX (15);
myChart_Prices.setAxisValuesDecimals(0)
myChart_Prices.setAxisNameX ('Days');
myChart_Prices.setAxisNameY('Cr');
myChart_Prices.setIntervalEndX ( 0);
myChart_Prices.setIntervalStartX ( -30);
myChart_Prices.setTitle('Market Price History for Cargo item');
myChart_Prices.draw();

Have i missed something?

This is pretty important as it is the only problem i have encountered with it and i will be buying the multisite licence to use it if i can get this sorted.

Cheers

Kay.

P.s. And no...just ignore it as it has no impact is not an option...lol. Those little yellow warning symbols are the bane of my life. :)

How to Hide Axes in JS Charts? (1 reply)

anongdu — Fri, 23 Apr 2010 13:52:01 -0500

Hi All,

Was wondering if anyone can help me figure out how to NOT DISPLAY axes for line and bar charts. When I set the axes width to 0 it seems to work OK in Firefox but not Chrome. Is there a method I'm overlooking?

myChart.setAxisWidth(0); //works in Firefox but not Chrome

How to Overlay text on Chart (no replies)

cteufert — Thu, 18 Mar 2010 10:47:45 -0500

While working around not being able to set the position of the text in the titles I came up with the following code. It simply draws text on the same canvas as JSCharts does. Not sure if it works with IE but it does work with Firefox, Chrome and Safari.
Charlie.

function overlayText() {
var canvas = document.getElementById("JSChart_mycanvas" );
    if (canvas.getContext) {
        var ctx = canvas.getContext("2d" );
        ctx.strokeStyle = "rgb(0, 0, 0 )";
        ctx.strokeText("Hello World. ", 10, 17 ,10 );   
             //strokeText("text to display", x pos, y pos, char width)
    }
}

creating varying ammount of series (no replies)

Baka — Sat, 13 Mar 2010 04:49:13 -0600

Hello,

I need to create a chart with varying amount of series (which are based of number of checkboxes selected). Problem is that if i try to use a cycle for series creation(commented text), chart creation fails ("Your browser does not support chart object" is shown). If i use manual input - meas_chart.setDataArray(chart_array[0]); and so on, graph is displayed correctly, but, of course, control on amount of series is lost. Is it possible to get a workaround for this problem?

Simon

EDIT

was stuck on this problem for few days only to miss an illegal variable declaration 8-)

Your browser does not suport chart object

bacalao — Thu, 18 Feb 2010 07:54:57 -0600

Hi,

I'm trying to make a burndown chart with the jsCharts package (hours remaining in a project over time).

I know that jsCharts won't recognize dates, so I use day numbers in stead in order to get the correct spacing in the chart.

Is there any coorect way to show dates? What if I feed the chart with one value per day? Can I set a caption or text for my values on the x-axis?

I am trying to use JCHART, and I have 2 Graphs that need specific colors. The code that I have implemented changes the color of the charts on every load of the data.
