  • Passing variable to Google Charts URL

    - by Rob A
    Hi All, This is probably something really simple, however I am quite new to PHP, and havent done any HTML in years. I need to get a PHP variable filled with an array of figures into Google Charts. My code for this so far is: <img src="http://chart.apis.google.com/chart? &chs=340x175 &chd=t:<?=$filedetail[1]?> &cht=lc &chtt=Test "> However, Google reports an error, as it stops at the ?=$filedetail[1] for some reason. It doesnt seem that reading the variable is the problem, more that the API simply cant read past the start of the PHP tags. Thanks, Rob A.

  • Scrum burn down charts, can they go negative?

    - by AaronThomson
    I work on a small Agile development team which is part of a large, non-agile thinking corporation. Currently, we practise Scrum and occasionally, we exceed our sprint commitment. My question is, how do you handle burn down charts when you have exceeded your sprint commitment? I can think of two options: Extend the y-axis in the negative direction and keep counting down Add more cards/stories/work and have the burn down value increase by that amount, burning down when that work is finished. The ultimate solution for my team is one which is clear to the business and adds real value for the developers. So far, neither of these solutions has worked out perfectly.

  • Resources for how to design graph/charts well

    - by wesgarrison
    One of my projects needs to show users where they rank in certain calculations. I inherited the graph structure from the previous programmer and had to leave it alone while I worked on other parts of the site. It's time to make the graphs more meaningful, so I'm looking for books/websites/etc about graphs. (Not graph theory!) Charts that convey comparisons at a glance. Everyone suggests The Visual Display of Quantitative Information by Edward Tufte and that's spot on for what I'm looking for, so anything related to that would be great. Naturally, personal experience about what to do or not would be helpful as well.

  • charts, forms and credit card payment in drupal

    - by mingos
    Hey. I've got this client who's a dietician and wants a site with some functionality I'm not sure how to implement: custom forms that calculate some stuff (like ideal body weight, based on a bazillion factors), the user is supposed to be able to pay for the consultation with a credit card - which lets him access more consultation forms, bi-weekly results from how a user's diet is going (weight reduction and so on) should be displayed using a series of charts, preferably in the user's account page. I use Drupal exclusively, so the question is whether such functionality can be implemented using existing modules? Which modules would you recommend? Can this be achieved without writing custom modules (I've never written a Drupal module)? Thanks in advance for your suggestions.

  • timeline charts with rich ui

    - by Karthick R
    hi all, I have a requirement to come up with a time line chart and a few more controls on a single page[with rich ui]. I have short listed Flex, JSF[apache trinidad], html5, gwt these technologies. None of them provide timeline charts on their own. I am looking at other options such as using third party libraries. The chart should have drill down capabilities as well. Let me know if there is any specific technology that I should try. regards

  • Google Charts - Adding Tooltip to Colorized Column Chart

    - by David K
    I created a column chart with google charts that has a different color assigned to each column using the following posting: Assign different color to each bar in a google chart But now I'm trying to figure out how to customize the tooltips for each column to also include the number of users in addition to the percent, so "raw_data[i][1]" I would like it to look like "70% (80 Users)" I understand that there is "data.addColumn({type:'number',role:'tooltip'});" but I'm having trouble understanding how to implement it for this use-case. function drawAccountsChart() { var data = new google.visualization.DataTable(); var raw_data = [ ['Parents', 80, 160], ['Students', 94, 128], ['Teachers', 78, 90], ['Admins', 68, 120], ['Staff', 97, 111] ]; data.addColumn('string', 'Columns'); for (var i = 0; i < raw_data.length; ++i) { data.addColumn('number', raw_data[i][0]); } data.addRows(1); for (var i = 0; i < raw_data.length; ++i) { data.setValue(0, i+1, raw_data[i][1]/raw_data[i][2]*100); } var options = { height:220, chartArea: { left:30, width: "70%", height: "70%" }, backgroundColor: { fill:"transparent" }, tooltop:{ textStyle: {fontSize: "12px",}}, vAxis: {minValue: 0} }; var formatter = new google.visualization.NumberFormat({ suffix: '%', fractionDigits: 1 }); formatter.format(data, 1); formatter.format(data, 2); formatter.format(data, 3); formatter.format(data, 4); formatter.format(data, 5); var chart = new google.visualization.ColumnChart(document.getElementById('emailAccountsChart')); chart.draw(data, options); }

  • Need help starting with DSL for charts/graphs

    - by Rex M
    I am unaware of any established work into Domain Specific Languages for describing charts / graphs. I am looking for specific answers of "yes, something like that exists (here)". To help be clear, in case I am possibly using the wrong verbiage to describe it, to me a DSL for charts would most certainly include: A grammar for describing the shape of an expected data set A grammar for describing a pipeline of behaviors that render an output Abstract / high-level enough to be mappable to most tool-specific grammars, such as Excel, Highchart, matplotlib, etc.

  • how to set custom interval to horizontal axis in Flex Charts

    - by Ali Syed
    Hello folks, I am trying to set custom step (interval) to my Line Chart's horizontal axis. The chart gets its data from a grid. The grid has a lot of data and it is displayed accurately but because there are so many data points the horizontal axis is screwed up. I wanted to set a step on horizontal axis so that you get an idea when you see the graph without hovering the mouse on a data point! thanks for any help! -Ali Flexi Comment Box

  • Google Charts: Bar chart labels are reversed

    - by True Soft
    I create dinamically a chart for a website. I have a key/value map, I sort the values descending, and then create the url: http://chart.googleapis.com/chart? chs=400x200&cht=bhs&chbh=a&chdlp=l&chg=25,0&chma=0,0,0,5&chtt=Chart+test& chxr=0,0,8,1&chds=0,8&chxt=t,y& chd=t:8,5,3& chxl=1:|Label_8|Label_5|Label_3 The values are set by chd=t:8,5,3, and the labels are set by chxl=1:|Label_8|Label_5|Label_3. However, in the chart image the labels are reversed. I searched the documentation, but I didn't get why it is like this. Is it because I didn't set a value correctly, or is this the desired functionality? I could reverse the label texts in chxl from code to be displayed how I want. Is this the right way?

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • How do I export charts from Excel as graphics

    - by user83266
    I've got a series of Excel spreadsheets, each with at least one page of data and one page of a chart created from the data. I need to capture ( not regenerate from the data ) the existing chart as a web friendly image. Is this possible via Java or .Net? I know the POI stuff (Java) won't do it (or so I'm told, haven't tried it myself).

  • graphs and charts on the iPhone

    - by Jon
    My client has requested data to be presented in a graphical format on the iPhone (a pie chart or something similar). I am wondering how others have handled this - A.) deliver the raw data to the phone and somehow build the chart on the phone, or B.) have the back-end services build the chart and deliver it (png format) to the phone? Thanks for any advice.

  • SOCharts: Charts by Tags

    - by abhin4v
    Screenshot I created this small app as a weekend hack. It shows the reputations, upvotes, downvotes and accepted answers for a user against the tags for the answers. About I wanted to know how may upvotes I was away from getting the bronze badge for the clojure tag. But I could not find any straightforward way of doing that. So I wrote this app (in Clojure, of course). The SO API is used for the data and the charts are created using the Google Chart API. The charts are opened in the default browser. License Licensed under EPL 1.0. Download If you have Clojure and Leiningen installed, you can simply get the code from https://gist.github.com/725331, save it as socharts.clj and then run lein repl -e "(load \"socharts\")(refer 'socharts.socharts)(-main)" for launching the Swing UI If you don't have Clojure installed, but have Java then download the standalone jar from http://dl.dropbox.com/u/5247/socharts-1.0.0-standalone.jar and run it as javaw -jar socharts-1.0.0-standalone.jar Once the UI is launched, just type your user id in the input box and press <ENTER>. It will take some time to download the data from the SO API (the progress bar shows the download progress) and then it will open the charts in your default browser. You can also run it as a command line app by running lein repl -e "(load \"socharts\")(refer 'socharts.socharts)(-main <userid>)" or java -jar socharts-1.0.0-standalone.jar <userid> where you replace <userid> with your user id. Be warned that because of a missing feature in the SO API, it will fetch the data for each question you have answered. So the maximum limit is 10000 answers (the SO API call limit). Platform All platforms with Java 1.6. Contact You can reach me at abhinav [at] abhinavsarkar [dot] net. Please report bugs/comments/suggestions as answers to this post. Code Code was written in Clojure with the UI in Swing. It is available at https://gist.github.com/725331. It's a public gist so your can fork it if you like to do some changes.
