Zooming Feature
posted
Hello, I'm currently downloading the evaluation version of webchart and am wondering if i'll be able to enable zooming in a chart (similar to the finance.google.com zoom behavior) whereby a user could select a portion of the chart to zoom in on in addition to having crosshairs available to determine the exact values at a given point on the graph. thanks, _Ramy

    You can see a simple example of what Tony's talking about at componentsforjsf.com.

    Under the "test Drive" category, click on Showcase Apps, and then select Dynamic Charting.

    Incidentally, NetAdvantage does not currently include a slider component, but one should be available in the near future.

    Thanks,
    Jim

    The chart doesn't expose zoom functionality to the end user, so you would have to provide a mechanism for the user to zoom in.  You could have a set of predefined zoom points and use a WebSlider to change the zoom ratio.  Alternatively, you could get even more advanced and track mouse movements to zoom in on specific areas.  It would be a bit of work on your part, but it's something that is possible to acheive.  Crosshairs are already built-in.
