Using Google Charts API With Lotus Domino

I just updated the DEXT survey demos to include a graphical image of a pie chart, rather than the amateurish bar charts created with CSS. You can see an example here:


Looks good doesn't it. Wondering how complicated it was to do? Be surprised if I said it was very, very simple?

Earlier on today I Tweeted about how much I was liking the ASP.NET's built-in Chart component for creating charts on the fly. In reply my wife's friend's husband suggested I look at the Google Chart API, which is what I've used to create the charts above.

So simple it hurts.

I won't bother with a "how to" as it's very simple and well documented on the Google Charts site I just linked to.

Obviously it's a simple way to add a chart to a page generated with any server, so why did I add Lotus Domino to this blog's title? To keep the people who voted "no" in the this survey :-)

At some point soon I'm planning on adding the surveys to this site itself. I'll use the Google charts when I do.


  1. What would be cool is if there were a bunch of reusable XPage controls that utilizes this API and you can bind to Notes/Domino data.

      That would be great. I considered trying to do that with the Dojo charting but never have had the chance.

  2. Dojo charting give you those capabilities also.

    1. Without having to make a round trip to google to get your chart; however the dojo ones don't look quite as good.

      Forgive my ignorance of all things Dojo but how does it do it? It's a JS framework, so how does it build images - does it use SVG/canvas?

  3. Bruce,

    True. But it is improving.

  4. Thanks Jake, very useful

    As for the relevance to Domino - well just create an xPage with an image and compute the URL for the image.

    As a two-minute test my image url was grabbed from the Google wizard then split up like this:

    var baseURL = "http://chart.apis.google.com/chart?" ;

    var chartstyle = "chxt=x,y,r,t&chs=300x150&cht=bhs&chco=3D7930,A2C180" ;

    var axis1 = "32.787,57.377,34.426,75.41" ;

    var axis2 = "19.672,9.836,26.23,16.393" ;

    baseURL + chartstyle + "&chd=t:" + axis1 + "|" + axis2 ;

    The axis numbers could very easily be replace by @dbcolumn / @dblookup

    Of course I look forward to someone building a re-useable control as discussed above, but it's pretty easy to get started now (much easier than Dojo charts).

    I prefer flash based charts.. Fusion charts are great , you can download most of the frequently used charts for free.

    Should see High Charts - http://www.highcharts.com/ - is js based, no reliance on flash, etc.

  5. It's a good choice but there are drawbacks :

    - data security

    - accesibility

    I love the Google-O-Meter Charts , I don't know another tool that provides that.

      Indeed. As with any tool, you have to use best judgement. For the actual app I'm working on I wouldn't use it, as it needs to be secure. For this site's surveys it's perfectly fine.

    One recent update for FusionCharts that seems to be very good - is a dynamic use of HTML5 - so they work on iPhone/iPad etc without needing to build additional fallover options in.

    1. oooh

    Hi Jake,

    We like them as you can get a proof of concept up and running in next to no time - without having to mess about with any third party components.

    We're quite happy with how Google Charts performs, we use it heavily on some BI dashboards. We've also built a wrapper control which allows us to just pass it a chart type along with all the collections of data and the control handles building the querystring itself for the image src itself.

    Combine this with jQuery and you have a fairly flexible way of creating charts and updating them asynchronously.

    Like you say it's choosing the right tool for the job - but not a bad path to go down all the same.


    (wife's friend's husband :)

  6. Jake,

    Dojo using SVG. It is not as good as the Google Chart yet, but it is getting better.
