new to steema need help with 3dcharts
Hello, I have made a few application with the trial api and have decided to purchase. I copy over the new download with the latest version. Lots of area confuse me a bit so I will list them all sequentially.
1)how to despose of a chart? I can not figure out how to properly dispose of a chart and not sure its needed. What I do for now is just remove the canvas ( ....removeChild( canvas01 ); )
2)how to use an array without eval'ing it?
The following works.
surface.data.labels = eval( "[" + this.Xdata.toString() + "]" );
surface.data.labels = new Array(...)
this does not
surface.data.labels = this.Xdata
Xdata is defined as an array, why does that not work( map is empty)?
3) Can not make a 3rd dimension label? Looking at the 3dchart as it is without moving it. I can label X and Y but not Z?
4) Can the 3d charts support movable points? If not can this be added somehow?
5)where is the complete api? I dont see "Tee.Three" in the Class Index for example. There is so much that is not document ?
6) browsers
-- does not work on opera error: Error thrown at line 30, column 50 in <anonymous function: clearRect>() in http://localhost:62578/SCT/steema/src/teechart-3d.js:
-- does not work in IE 10: Unable to get property 'add' of undefined or null reference teechart-3d.js, line 30 character 51
-- does not work in safari: no idea why, cant find debug messages.
I'm very impressed with the charting so far, hope you can assist with the above!

Hi,
If you want, you can take a look at the details of the memory that is being used with the developer tools or similar
https://developers.google.com/chrome-de ... -profiling
Don't hesitate to let us know if you still find problems with any of the above.
As far as we know, there's no function to manually dispose memory in JavaScript. There's a garbage collector that should release the memory a variable uses when it finds it won't be used any more.sct wrote:1)how to despose of a chart?

If Xdata is an array of numbers, you could do as follows:sct wrote:2)how to use an array without eval'ing it?

Code: Select all
var result=[];
for (var i=0,l=this.XData.length;i<l;i++) result.push(this.XData[i].toString());
surface.data.labels = result;
I'm afraid there's no depth axis in TeeChart JavaScript yet. This is a feature to be added in a future release with the possibility to have 3D non-orthogonal charts without WebGL.sct wrote:)3) Can not make a 3rd dimension label?

I'm afraid not at the moment. I'll add this to the wish list to be implemented in future releases (TF77016688).sct wrote:4) Can the 3d charts support movable points? If not can this be added somehow?
I've updated the link to the API in the Specifications tab in the TeeChart HTML5 page to point to the latest version of the API. The Three section isn't finished but at least you'll be able to see the structure.sct wrote:5)where is the complete api? I dont see "Tee.Three" in the Class Index for example.

You have to add the following to go back to HTML5 canvas when WebGL isn't supported in the browser. This code can be found in the webgl demos and an explanation can be found here.sct wrote:6) browsers

Re: new to steema need help with 3dcharts
Yeray, I'm aware of the GB collection and agree there should never be a need for that. I was more concerned about the code on your end and if there was a need for it. That clears up the question for me.
surface.data.labels = new Array(...)
and this does not
surface.data.labels = this.Xdata
?
TF77016688 -- looking forward to that.
I put this code in my 3d draw but I get the errors I mentioned before during my 2d draw before I ever attempt the 3d. Interestingly I never see this alert. It's bit hard to follow "go back" to since in my cause I can not get to the 2d map to start with, without errors . Maybe I dont quite follow yet. Do I need this check for my 2d map before I ever attempt a 3d map?
My work around with eval works I'm just so baffled as to why this works:If Xdata is an array of numbers, you could do as follows:
surface.data.labels = new Array(...)
and this does not
surface.data.labels = this.Xdata
?
As long as its on the todo that works for usThis is a feature to be added in a future release
TF77016688 -- looking forward to that.
I saw this reference and I used it like so.You have to add the following to go back to HTML5 canvas when WebGL isn't supported in the browser. This code can be found in the webgl demos and an explanation can be found here.
Code: Select all
if ( three.isEnabled() )// Valid webGL ?
{
this.Chart1.draw();
animate();
}
else
alert("error: NO WEBGL SUIPPORT")
function animate()// Loop
{
three.update();
requestAnimationFrame( animate );
}

Re: new to steema need help with 3dcharts
I fixed the array issue by doing this. ( I hope is ok to share source on this board ? )
Code: Select all
Tee.Series.prototype.valueText=function(index) {
var vv=this.data._old || this.data.values, d=vv[index];
if ( typeof d == "string") d = Number(d);
if (d) {
...

Hi,
Thanks for the comments and for sharing the solution to the array problem.

Re: new to steema need help with 3dcharts
I'm not having luck with the setEnabled. I tried to put it in various places and either I get a ghost 3d map or d.parentElement is null. This is how I currently do my 2d 3d switching. How would you recommend I do the setEnabled?
Code: Select all
chart.prototype.draw3d = function()

this.canvas = document.createElement( 'canvas' );

this.UIDiv.appendChild( this.canvas );
var Chart3d = new Tee.Three( "canvas" + this.id );// Create 3D WebGL context:
this.Chart1 = new Tee.Chart( Chart3d );// Create Chart:
this.Chart1.walls.visible = false;
this.Chart1.title.text = "Rotate with left click, scrole to zoom.";
surface = new Tee.Surface();// Create Surface:
this.Chart1.addSeries( surface );// Add Surface series to Chart:
var makeData="[[";//make data
for ( var d = 0; d < this.Zdata.length ; d++) makeData += this.Zdata[d] + "],[";//formate string
surface.data.values = eval( makeData.substring( 0, makeData.length - 3 ) + "]]" )

surface.grid.visible = true;
Chart3d.toogle( this.Chart1.walls, false );

Re: new to steema need help with 3dcharts
Note you have to add the helvetiker_regular.typeface.js and three.min.js scripts besides to the teechart-3d.js to make it run.sct wrote:I'm not having luck with the setEnabled.

Re: new to steema need help with 3dcharts
Hi,
And are the correctly loaded?
Please, check the demos included with the installation. If the WebGL examples work fine for you locally, you just have to do the same in your page.

Re: new to steema need help with 3dcharts
Everything is the same for includes. When I use the demo in IE,opera, safarI just get a grey blank map. Unfortunately dont get errors. FF is the only browser that for for me.
Re: new to steema need help with 3dcharts
This depends on the browser:
