I don't have any clue how to draw multi series spline chart using iText. I have done it on JSP page using canvas.js. I can't find any solution for iText. If any one has any idea or source to do it please let me know.

I have an simple SVG image created with Inkscape.Is there any way to view this SVG image as a figure in MATLAB?or convert the SVG image to any raster format such as JPG,PNG only by using MATLAB?I found exporting a figure to svg. but I want to import svg file as a figure/convert my svg image to any raster form.
Judging by this answer, this is not possible at the moment.
Undocumented Matlab didn't give any results either for possible Java solutions.
The only way is to convert to raster format outside of Matlab (or call the command line from Matlab using system). If you are on a Unix platform, ImageMagick can do that.
Dynamic Data Display is a fantastic library that so far has been very useful for me. Thanks go to Mikhail Brinchuk for developing the library.
This posting gives a great tip for adding controls to DynamicDataDisplay charts using xaml that pan and zoom with the chart content: https://dynamicdatadisplay.codeplex.com/discussions/74886
This allows the placement of an image, text, or whatever, on the chart that moves with the chart axes. This is all done in xaml.
How do I add these in the cs code such that I can add controls to the chart (markers, images and such) at run-time? I'm trying to plot some GPS data in one chart using Google maps as the source images. In another chart I'd like to add controls that pan with the data. The above link does this, but I am not able to add it at run-time, nor specify the position in my chart data.
I am a newbie to the graph functionality in an iPhone application.
I am having array of numbers for which I want to make the simple static line graph without using the coreplot library since I have already tried this which seemed to me quite complicated.
Can anyone please fix out my problem ?
You can draw Line chart using CoreAnimation.
Alternatively you can use core plot also : http://code.google.com/p/core-plot/
hi You can Draw your simple line chart without using core plot just refer following link.
http://code4app.net/ios/Line-Chart/4fc844616803faf26a000002
here you can get demo for simple line graph.
I hope this will help full to you.
I am trying to implement D3.js charts and using nvd3.js examples for it, I want to show two data set in one area(Means Want to Draw Chart for Sum of Facebook and Twitter positive sentiments with respect to time, in one area chart with respect to time). And want to show one tooltip which shows indvidual contribution of facebook and twiiter and total, As you can see in Attached image. I have done only for facebook or twiter not for both in one chart.

I'm writing a stock charting application on iPhone using core-plot. What kind of chart should I use to plot the volume chart? Since I will also need to overlay the price charts onto the volume chart, how should I go about doing this?
Here's an image for reference (By no means am I trying to reimplement stockcharts functionality, just wanted to create a simple charts with volume information overlaid on the price charts):

What about using a Javascript charting library inside a WebView for your charts? You could then use something like Emprise: http://www.ejschart.com/
If you look at the latest builds of the framework, Drew just added an open-high-low-close plot type, which is a CPTradingRangePlot with a CPTradingRangePlotStyleOHLC plot style. For an example of this in action, along with a bar chart tracking trading volume, see the latest version of the AAPLot example application that ships with the framework:

Well i don't think its possible using current build of core-plot. But you can write a implementation of your own OR in best case extend core-plot to do that & submit a patch so other can benefit from your work.
Read Quartz 2D Drawing API & you will easily be able to create a complicated graph like above.
