Thread: Google Finance style chart

  1. #1

    Default Google Finance style chart

    Does anyone know if it is possible to create a chart like those used in Google Finance's stock view?
    http://www.google.com/finance?q=csco

    It is essentially a line chart with a slider that extends the zoom'd in chart depending on a user's selection.
    Any examples of someone that has done this before would be great.
    Thanks

    I'm still getting my feet wet with ExtJS... but I've been looking into the same thing. You can probably do something custom with ExtJS... but I don't think it has already been developed.

    You can integrate Google's Annotated Timeline chart: (FREE)

    Or, maybe amCharts' Stock Chart (NOT Free)
    http://www.amcharts.com/stock/events/

    I'm also looking at how the chart on this site was implemented with ExtJS
    http://www.djindexes.com/

    I am currently considering the amcharts solution because I feel it may be little more flexible and time is more important than the license fee. I think you may be able to use the amcharts for free under some circumstances if you don't mind branding.

    Good luck!

    Check out High Charts: http://www.highcharts.com/, or PHP/SWF Charts: http://www.maani.us/charts/index.php.

    I'm also looking at how the chart on this site was implemented with ExtJS

    These ones look like they were done using rrdtool: http://oss.oetiker.ch/rrdtool/

    I was just wondering... which HighCharts example sold you on them? I thought you were looking for a Google Stock type chart.

    I looked at Highcharts in my revew but none of them seemed to have the built in interactivity. I figured I could program the extra tools in but I wanted to see them in action before committing. I'd love to hear more about your implementation.

    I'll try digging up a demo of what we're doing with amCharts. I'd really like to use something that isn't flash based since the iPad/iPhone hates flash... but flash seems to be where highend chart is at.

    The 'master-detail' and 'time-series zoomable' charts do the job for what I'm after. Once I got the software loaded on my machine, I was able to have a prototype up and running very quickly. Now my only problem is loading data in from a mysql database. I'm all ears if anyone has any ideas

    I agree I think HighCharts is one of the better ones out there. StockCharts is excellent well. For good intra day charts and 1 year charts I like to use BigCharts; not as technical as the others but a great charting tool none the less.
