I've recently upgraded to the latest version of Highcharts v3.0.2 and now one of my existing charts is rendering in a strange manner. See 'Sector Chart' at this link
http://bit.ly/10hU8TW
The circles seem narrow and out of alignment. Can anybody point me in the right direction to solve this?
Many thanks
Please take look at v3 configuration of http://www.highcharts.com/demo/pie-donut

I am new to WebAR, but I have experience with building AR scenes with Unity3D and software such as Vuforia and 8thWall.
I have a question with the markers with AR.js. Why are they stuck with the thick black border? Is the software not able to just recognize a unique image like how Vuforia and Wikitude works? I apologize for how naive I may be when it comes to WebAR, however, I see this as an issue for the adoption rate of this technology if developers cannot use truly custom images and patterns. Is there a solution available that I may have missed somewhere? What happens if someone deletes/erases the big black border on the marker? Does it still work?
Thanks to anyone who can shed some light on this!
Ar.js uses artoolkit and therefore is marker based. If you want to use it, there is not much you can do about it. Still You can have unique images inside the black box but not much else.
Worth mentioning, it is possible to make the borders thinner, there's even a branch - work in progress worth looking into.
Aframe-argon tried integrating aframe and vuforia, but i'm not sure if it's up to date.
i am looking to make a pie chart. but there are so many ways to make it(calayer,bezierpath, thirdParty tool ) which make me confuse. i haven't have enough days to look into each implementations.Can anyone with a experience in making charts guide me on making such Piechart.
Thanks in advance.
i just ended with third party tool. thanks everybody.
I need to draw a chart as seen in attached image using highcharts or any js library but i am not getting any lead. Anyone any thoughts?
This is an older question but I just ran across it while looking for how to display a similar chart: one that shows median and standard deviation around the median, but also can show the outlier low and high values. Highcharts actually has a very good solution for this called a boxplot that I eventually stumbled across. I mention it here in case it can help someone else. Worked well for me and I think would have worked well for the OP (with some modification).
Here is the highcharts demo page:

We were using Delphi 2010 with the full VCL edition of TeeChart this worked fine
We have now updated to Delphi XE 5 with the latest version of TeeChart and the quality of the charts is now worse
Please see the image here
2 bars which were seperate are now merged into 1 bar
If I make the charts wider which is not an option it looks better but still not as good as before
Please see here
Has anyone come across any issue like this?
The projects are here for Delphi XE5 and here for Delphi 2010
The search paths may need modifying

The issue might be because of the anti-aliasing function being turned on by default in the newer versions of TChart(!).
We had the same issue with a line series graph.
After writing to the vendor (Steema) they came up with the following solution:
Chart1.Canvas := TTeeCanvas3D.Create; //Disable GDI+ to prevent smooth drawing of the graph.
I don't get why we have to switch off drawing with GDI+ as - to my knowledge - GDI+ can also be used without anti-alias.
Anyway, our graphs now behave like the previous versions of the TChart, which is what we want.
I was also hating the "new" anti-aliased charts that are blurry and slow.
It's pretty easy to fix, when you know where to search for.
Double-click on chart, then go to 3D -> Render -> select GDI instead of GDI+
If you look "behind the scenes" into DFM file you can see the change:
Crisp and fast graph (as in 2010): DefaultCanvas = 'TTeeCanvas3D'
Blurry and slow graph (as in XE5): DefaultCanvas = 'TGDIPlusCanvas'
chart settings
Hope this helps.
Some kind of a clumsy runtime workaround was found here, that is also working:

For my client I have to develop a dashboard for the iPad (in Monotouch), showing several charts. Is there a chart component available for MonoTouch? Or does anybody have an idea to generate charts for the iPad?
Thanks,
Danny
There are a couple of commercially available chart components with MonoTouch bindings:
ShinobiControls - have launched a beta of their bindings
Steema Charts - have MonoTouch bindings
I was looking for such a control for charting but haven't found one. I draw my graphs manually. After all it is not so big deal just a bit of math. I draw pies and bar graphs.
