Grid Chart using GWT - gwt

Is there any library in gwt that will create grid chart, something similar to this : http://www.eyescience.com/images/vision/amsler_grid.gif.
Thank you.

Look at the following url.I think google visualization api will be useful for your case(try Scatter chart).

If you are considering restricting yourself to browers that support Canvas, GWT has experimental support for that.

Here's a nifty demo:

Google Web Toolkit With Line/Pie Graphs

Currently I am using Google Charts with Google Web Toolkit but I wanted to explore other options for graphing. I looked into jGraph and the gwt extension mxgraph but that seems to only support actual graphs for flowcharts/diagraming?
Is there any other library (other than Google charts) that I can use to visually show line/pie graphs?
Thanks
Please have a look at high level visualization charts

And wonderful showcase here

Hope that helps.Good luck.

chart library which can edit graph by dragging points?

I'm looking for preferably javascript (but flash would do too) charting library which would be able to render time series as line chart and then allow to drag points in chart to change the underlying data.
I was said that Excel can do exactly the same thing, but I need it on web. No well-known charting library like Highcharts, amCharts, GoogleCharts or dygraphs cand apparently do that - I found some draggable graphs solutions like WireIt or http://radokirov.com/js-graph-editor/ but these are nodes and edges types of graphs not really-usable for chart drawing.
Do you know any ready for use solution to this problem? I don't care whether it's opensource or commercial.
Late response; I might help future visitors, though.
I'm looking for something similar. try: http://www.jqplot.com/deploy/dist/examples/customHighlighterCursorTrendline.html

Using charts with gwt

I am doing some stuff with gwt, Now i need to draw charts. Actually pie chart and line chart.
Is there any library for chart which works well with gwt?
Check out Google API Libraries for Google Web Toolkit. There you will find a link to Google Chart Tools
There is also OFCGWT chart widget for GWT based on Open Flash Chart 2. Here is its demo
Except this you can check out these:
charts4j
clientsidegchart
RaphaelJS GWT wrapper, there is also one called raphaelGWT which is not developed actively.
I've already use Google Charts, and I preffer
GWT-HighCharts you can see why checking it showcase.
Check out http://code.google.com/p/gwt-rcharts/ and its demo at http://gwt-rcharts.appspot.com/ with code snippets on how to use it, which is quite easy.

Is there a good iPhone pie chart library which will produce good look 3d pie charts?

I can't find a library which will produce good looking 3d pie charts for the iphone?
I had a look at the core plot wiki and their pie didn't look that good...
There's an open-source class called BNPieChart available in the moriarty library which can produce pie charts like this:
(source: bynomial.com)
And also much smaller versions of course. There's a post about it here.
Besides NBPieChart proposed above, have a look at XYPieChart it is a really good open source pie chart that looks very nice, are extremely simple, and contains animation for adding slices. Look at the screenshot of the demo project included:
There's also Fusion Charts, which is now HTML5. http://www.fusioncharts.com/
Core Plot has been recommended in other postings here on stackoverflow. It supports many standard data visualizations, including pie charts.
The Google Chart API is pretty good/popular.
http://code.google.com/apis/chart/ You will need a network connection though.
If you want iOS native charting library you should check ShinobyControls.
If you want web-based, and also amazingly good charting library, maybe HighCharts is the way to go.

Advice for building simple bar chart, but with custom styling

I have some data that is displayed in a bar chart, using Google's Visualization API. Was simple enough until designers redesigned it... Now it appears to be something that is beyond what Google can help me with.
Given the attached mockup (and note the finer details like reflection and gradients!)- how would you go about building it? Using some existing graphing libraries? Homebrew from the ground up?
Thanks for any advice.
If you need to adhere to the custom design requirements as depicted in the image above, I would build a charting application using a more generalized graphics library such as Rapheal.
While it doesn't provide a simple API for plugging data into a chart, it does provide the ability to build a chart with the following:
a variety of shapes (i.e. the bars)
gradients
embedded images (i.e. the background)
You can change the visual effect using CSS.
Ofcourse you can use chuckx recommendation of Rapheal which is a SVG based Javascript Library. It can accept JSON values so say if you have JSON from Google API you could feed in directly.
Option 2 : HTML Canvas. There are lot of HTML 5 canvas libraries like Kinect, fabric.js powerful javascript canvas libraries
