I have a fairly simple mysql database. I want to extract data from it and display as a graph to analyze it. Nothing advanced, just line diagrams and such. As a programmer I can always write some code for this myself. But does anybody know of a program that can load data (using sql queries?) and display it in various graphs?
Checkout DBPlot for Windows environment.
You can also have a look at Google Charts, if you want your graphs displayed in web pages.
Don't know what type of output you're looking for, but FusionCharts has helped me a lot... http://www.fusioncharts.com/free/
You can use GNUPLOT if you are in linux environment. I am currently using this for generating automated EOD reports which contains graphs. The graphs are drawn using the data fetched from mysql (Currently we are using in csv) But gnuplot is not as good as Fusion Chart in UI Perspective
I'd have to recommend JQplot if you want these graphs in web pages - it's non Flash (hooray!), uses JQUery (hooray!) and has some very, very cool features (hooray! - check out the examples page).
As per the docs page, you can just pass an array of values to it and it'll plot what you want, and generating an array is simple in server side languages such as PHP.
Hope this helps,
James
An extremely flexible library for graphs (images and applets) would be JFreeChart.
On the other hand, if what you actually need it is a reporting engine, Jasperreports should be your first and final stop but you will have to do A LOT of reading before starting doing something with the latter and it won't be time lost for nothing.
Try Smart chart maker it is used to create many type of charts that can be fed from a MySQL database . supported chart types include line charts , pie charts, bar charts, and scattered charts.

It seems most Bokeh embedding examples are using bokeh.plotting.figure object. Is it possible to embed a high level chart, like bokeh.charts.Bar or bokeh.charts.Scatter? Or is it possible to have convert a high level chart to a bokeh.plotting.figure object?
Thanks a lot.
The User's Guide section on Bokeh APIs has a good run down of how all these parts fit together, that I would suggest reading.
The long-story-short: Regardless of what API you use, bokeh.plotting or bokeh.charts, the end result is always just a collection of the same low-level bokeh.models objects. You can can think of bokeh.models as very basic building blocks, and the other higher level APIs as conveniences that help you to assemble the building blocks more efficiently and correctly.
So, in that light, yes, it is perfectly fine to embed a bokeh.chart using exactly the same functions described in Embedding Plots and Apps.
The one thing I will add is that if you need to update the plot's data after the fact, in place, then the bokeh.figure API will probably be more straightforward. The mapping between your data, and what gets plotted is more direct. Things generated by bokeh.charts may transform your input data into entirely different forms before plotting (e.g. you give a series, and Histogram has to spit out coordinates for boxes—not the data you started with)
I start to use dygraph and I found some difficulties to work with independant series, specially because I have a voluminous data, is there any solution to work with independent series without formating data to especial format recommended by dygraph?
Thank you for your help
You can use a Google DataTable to manage large data series.
We are currently integrating with SQL Server Reporting Services and have got most of the functionality we require in place now but I am stumped on how do get the last bit working. On the current manual system at the bottom of the Excel spreadsheet is a Word Cloud which we would like to emulate in SSRS. I have constructed a DataSet that returns a list of words and their scores but I cannot work out how to create a word cloud from it.
I have followed the example below and got it working successfully and it looks great in Visual Studio but when I look at it in Excel and as a PDF its just not very nice at all.
http://www.sqljason.com/2012/03/making-tag-cloud-with-ssrs-rich-text.html
The main problem is that the results are loaded into a table (that has to be shrunk so it is unobtrusive) the some VB generates the HTML that is then rendered in a Text Area.
When I look at it in Excel the table is clearly visible (its huge) and in PDF form it is missing.
Does anyone know of an extension or plugin that I could use to display the word cloud or a better way of doing it?
The alternative would be to embed it as an image and call a web-service that creates the word cloud on the fly but it does seem like a lot of work for something that is probably a fairly common requirement.
Thanks everyone in advance :)
You say it does not look nice and then that it is missing. Which one? Why are you having to use a Dataset for words generated? If they are just arbitrary words you could set them up in free floating text boxes. I am not getting why to generate text you need to apply a dataset to it unless there is an object like a 'list' you have rules that you HAVE TO use a dataset.
Without a picture (which you do not have enough points to show) it is hard to tell what the cross applicatin problem could be. You are using a blog as a basis which the person could be using 2008R2 or 2012 SSRS for as well which makes it hard to troubleshoot.
My guess is you are applying a boxing layer, positioning or overlay that the PDF renderer does not like. My suggestion would be to start a small report with just his example only and see if it works as is in 2008. He seems to have someone mention on an issue of positioning which is the biggest culprit of problems with SSRS and multi format saving. If you can get the CORE part of your report working as he described I would think you may be able to use that as a 'subreport' inside of another report if you want more than one object to a report.
I'm looking to identify some possible software options that will allow for custom rules to manipulate bulk data files (.csv) For example, proper capitalization (allowing for states to remain capital and unique surnames), identifying the word count of specific words in a field, and some other custom rules. Any guidance would be appreciated.
You could use Talend Open Studio for this task. It is an Opensource ETL tool for data manipulation and integration. You can for example ImportCSV >> DATABASE >> perform transformations >> ExportCSV. The possibilities are endless.
You can find it here: http://www.talend.com/products-data-integration/talend-open-studio.php
It also sounds like you might be looking to create a profile of the data. For this you can use Talend Open Profiler, they recently added support for flat files such as your .csv. It is simple to use and you should be up and running in 30 mins.
You can find the download here: http://www.talend.com/products-data-quality/talend-open-profiler.php
You can find some tutorials here:http://www.talendforge.org/tutorials/menu.php
On the tutorials choose the Data Quality tab, and scroll down until 'Talend Open Profiler'
It is my first step in assessing data quality on a new dataset.
A quick google "data scrubbing utilities" turned up this:

They look to be very close to what you're looking for.
It'll really depend on how complex the rules get. Much more complex than simple stuff, and you'd probably be ahead by just coding something up (or having it coded).
I am designing software that needs to draw several different kinds of charts--bar charts, pie charts, flow charts/graphs, charts over time. I am looking for resources related to both the programming side of the issue as well as the UI/display side. Books, online resources would all be helpful. Thanks.
It does depend on the language a bit: here may be some pointers for you. Hope they help:

Practical C# Charts and Graphics
The Excel library can be imported by the Office API, but it does require you to have Excel installed.
Gnuplot
The grammar of graphics: book from the guy that wrote the plotting lib of spss. Somewhat theoretical, but nice xml treatment... gives you the graph xml schema for spss.
But I'm sure there are quite a few others that other people will know.
Do you have to draw it your self. If you want to save time (and probably money) then you can try embedding one of these into your apps http://code.google.com/apis/chart/
Ditto with Chris; If you are developing a new way of building charts, that's great!
Assumption: I have no idea of your needs but it would initially strike me (and thus form my assumption) that you are trying to develop a better charting software and that's usually interface.
Consider checking out the libraries in other programming languages that already do charting.
Adobe Flex/Air have one, PHP does, Java Does, .NET does.. etc.
Checking out the existing charing libraries for your language of choice helps a lot. In my case, it helped so much I decided not to write my own. ;)
For .net apps we settled on .netCharting, which can be pretty amazing.
The real lesson I took from it though, is this: there are way, way more kinds of charts than I thought there were, and I work with a lot of charts. Make sure you end up with something modular enough to handle clicking in new chart types / configurations with minimal effort.
You want to take a look at EyeSee.
