Is it possible to detect touchscreens directly with Highcharts ? I don't find what i want in the documentation.
I can use tools like Modernizr.touchevents but i don't want to import useless scripts.
Thanks in advance
Thanks a lot morganfree ! The solution:
Highcharts has property Highcharts.hasTouch which is used internally for checking for touch events - jsfiddle.net/yco2La86

I am using Contiki-NG OS and I pretend to plot some metrics but Collect-View is removed in Contiki-NG.
Could anyone help me with this issue?
Does any similar application exist?
Thanks in advance.
In contiki-NG there is a new application concerning power details of the motes.
A tutorial can be found in Energest: Energy Monotoring.
However, I don't know any application which can convert the data to a plot, like collect-view used to do. But I would also appreciate it if someone knew.
Is it possible to calculate Isochrones using Apple Mapkit? I'm not yet familiar with this API, thus I'd like to know in advance whether it's worth learning it.
Actually, I'd like to get all nodes on surrounding streets, in a given distance from a predefined point.
Thanks.
MapKit supports polygon drawing on the map. There is no isochrone function per say, it has to be built by you.
Check this out for details.
I know the post is a bit old but I want to suggest you the isochrone solution I've just developed: https://github.com/punkerpunker/isochrone. It might be interesting for you, works out of the box and solves task you've mentioned.
I am developing a simple multi touch table using only a projector and a web cam. I found out that i could use this Thumb and fore finger interface technique. but i don't have any clue of how to implement it. i think it can be implemented with OpenCV or OpenFrameworks and use with CCV. can anybody help me ?
Thanks,
You could go to the researcher's web site and download his recent papers about the subject. There the core parts of his technique should be explained.
i found something helpful here Thanks everyone.. and if you have any coding examples let me know.
I am looking for a quite specific tool for generating charts, within Ruby on Rails application. I have done a research and couldn't find a solution that suits me.
Maybe you've bumped upon it and could just point me to it with a link? :)
My requirements for a solution are:
it has to feature basic chart types
like Pie, Bar, Stacked Bar, Line.
it has to have basic configuration of
a chart like legend, axis
description.
it has to be able to generate and save chart into image file without
actually rendering it in a browser
being a Ruby library would be nice,
but it is not obligatory
not being Gruff Graphing Library, I
am looking for something more up to
date, with less issues.
If you are aware about something, please post a link - it'll take you just a few seconds.
I think, that it is what you're looking for.

I've made a number of useful charts with the Google Chart API. There are a few gems: googlecharts, gchartrb. I haven't used them but they look like a good first cut.
As to not displaying it you can just make the call and save the result. No need to render, just make the call, get the URL, and fetch the file.
The only one that has satisfied all these conditions:
I have been able to make it works without need of install weird dependencies
Not has an HTML context requirement (all JS libraries)
Not depends on GCharts (net traffic dependency)
Exports to static graphic format
is gerbilcharts
Chartkick!!!
It's super nice. =)
It's been a long time since I asked this question and I see new people coming and posting new answers, which his great. This small post of mine turned out to be a small compendium of available libraries.
I decided to add my two cents. Nowadays whenever I am dealing with charts I usually use Highcharts. Highcharts is a very pleasant library by itself, but additionally there is incredible gem highcharts_on_rails which facilitates creating charts using DSL written in Ruby.
If you found this question and you're looking for options, consider highcharts_on_rails.
This might be able to do what you want:
Gruff
You can use rchart for plotting various chart.
I am using openflashchart
http://pullmonkey.com/projects/open_flash_chart2/
you can save generated json data in database and render when needed
I have need to produce LINE, BAR, and PIE charts in Rails. I have found several that do all these. However the one caveat is that I can never find a solution that does all as well as XY-SCATTER. I've looked at Gruff,Scruffy,Gnuplot, etc. and none of them do "everything". Can anyone recommend a local (i.e. doesn't require network connectivity) library that can accommodate? GoogleCharts isn't an option as some of this will occur on closed networks.
Best.
If you don't mind commercial solutions, take a look at ChartDirector.
Open Flash Chart Plugin for Ruby on Rails - Graphs
FusionCharts is pretty good if you don't have a problem with Flash.
Have you checked Google charts? I'm not a web developer myself but it seems that, although not implemented in Rails, you can call the chart API and display the generated image.
Looking at the available chart types, it can give you all the types you want.
Edit: A search turned up this google-chart-on-rails wrapper.
