I have some code that worked with steema some time last year and I just updated to the saltest. Going through the code to make sure all is in order and ran in to this error. Here is my code leading up to the error. The very last line causes the error.

Code: Select all

         this.UIDiv.removeChild( this.canvas );
         this.canvas = document.createElement( 'canvas' );
         this.canvas.id = "canvas" + this.id;
         this.canvas.width = this.canvasData_width;
         this.canvas.height = this.canvasData_height;
         this.canvas.style.zIndex = this.canvasData_zIndex;
        // this.canvas.style.background = "#ffffff"
         this.UIDiv.appendChild( this.canvas );
         this.Chart1 = new Tee.Chart( "canvas" + this.id );

         this.annot = new Tee.Annotation( this.Chart1 );
         this.annot.position.x = 15;
         this.annot.position.y = 20;
         var anno = this.annot
         this.annot.mousemove = function () { this.text = ""; }

         if ( this.type == "Function" ) this.addData( this.Xdata, this.Ydata, .5, "ellipse" );
         else if ( this.type == "Table" )
         {
             for ( z = 0; z < this.Zdata.length;z++ )
             {
                 this.addData( this.Ydata, this.Zdata[z], .5, "ellipse" );
             }
         }
         //this.Chart1.legend.textStyle = "values"
         //this.Chart1.legend.legend_textstyle = "label"

         this.Chart1.tools.add( this.annot );
         this.Chart1.title.text = ""; 
         this.Chart1.axes.left.title.text = this.labelY; 
         this.Chart1.axes.bottom.title.text = this.labelX; 
         this.Chart1.tools.add( new Tee.DragTool( this.Chart1 ) ); alert( 5 )
         this.Chart1.draw();

Hello,

Could you please arrange a simple example we can run as-is to reproduce the problem here?
To attach an htm file you may have to zip it before.

Thanks in advance.

this seems to do it.

Hello,

It seems to crash because it expects the data to be doubles, not strings, when executing this line with d being the first value in the series "0":

Code: Select all

return d.toFixed(0);

I'm trying to identify what change in the sources affected this. Can you tell us in what version did that example work fine?

could have something to do with this
(see number 2) "how to use an array without eval'ing it? "
http://www.teechart.net/support/viewtop ... 18&t=14255
I had issues with that before.

This is what I found in the read me
Release Notes 14th December 2012
TeeChart for JavaScript v1.4
Sourcecode version 2012.12.14.1.4

I made it work with
this.addData( eval( "["+Xdata +"]"), eval( "["+Ydata+"]" ), .5, "ellipse" );
but not I get this error.
TypeError: text.split is not a function

Hello,

If the input data is going to be in that format, what about calling addData without changing any type and doing the job inside it?
Ie:

Code: Select all

addData( Xdata, Ydata, .5, "ellipse" );

Code: Select all

         dat.data.values = eval("["+ydata+"]");
         dat.data.x = eval("["+xdata+"]");
         dat.data.labels = xdata;

This works, will this be the best practices or would the API accept text at some point?

Hello,

I've added it to the wish list to be further investigated if we can implement some extra code to handle this situation:
http://bugs.teechart.net/show_bug.cgi?id=848

But in the meanwhile I'd consider the developer is the responsible to make sure data.x and data.values will receive arrays of numbers and data.labels will be an array of strings.
