  1. Please could you create a Realtime Scatter Chart or a Realtime Timeline chart.  

     

    I would like a chart like the Realtime Line Chart but one that I can add datapoints which have a value and a timestamp and have them plotted with an appropriate x-axis scale.   I presume this is not currently possible with any of the existing charts.

     

    Thanks,

  2. Although I have a nice "Loading..." message displayed for each chart, the performance via ajax/javascript appears a lot slower than via traditional direct dataURL links. I am using ASP.Net and AJAX with IE6.

     

     

     

    I have a dashboard page with 6 charts. When the page loads, 6 ajax calls are made to prepare the xml. On completion of each Ajax call the XML is returned and the chart rendered. I have it working with both setDataURL and setDataXML and both behave the same.

     

     

     

    I would expect each of my charts to render independently at slightly staggered intervals. However it seems the charts try to render together. At least 4 charts render at the same time (sometimes 5), meaning they start animating (or appear if I disable animation) at exactly the same time. This would be nice if it took only a few seconds, however it is more like 10-15 seconds after the first chart has received its XML.

     

     

     

    Its as if the flash charts are working together and when the first chart is ready it waits for the next, and the next waits for the next, and so on until there's at least 4 charts are ready and then they render together. The remaining charts then render once these finish animating.

     

     

     

    Is this by design, or is Flash/IE doing something? Thanks for advice as I'd like to use the AJAX methodology with each chart rendering as soon as it is ready. Giving users the perception of increased speed even if the whole dashboard is actually taking the same amount of time to load.

     

     

     

    Thanks. N.


  3. I've done something similar to this but my problem is that FC_Rendered isn't firing until after the chart has finished animating. Thus the chart has an ugly "loading..." message on top of it until it finishes animating. Of course I could get rid of the animation but that's one of the "wow" factors with your charts.

     

     

     

    Is there another option? A setting to get FC_Rendered to fire before the chart starts animating? or another event I can use to hide my loading message just as the chart starts to animate?

     

     

     

    I've been trawling the forum looking for a solution but haven't found one.

     

     

     

    Many thanks ...

     

     

     

    [EDIT :blush: - DOH!!! FC_Loaded does just the trick]


  4. I've done something similar to this using XY scatter and converting the x axis datetime stamp to the number of seconds from the start period datetime. Thus giving something like:

     

    y |                         x
    
     |                    *
    
     |          x *
    
     |    x *

    I'm facing the same problem. Sometimes all the charts render, othertimes one or two just say "Loading Chart ...". This also happens with the attached TestId example.

     

     

     

    I'd really like to use the DOM but atm it doesn't seem to work reliably. I am using IE6, with Flash 10.

     

     

     

    How do I use the RenderAllCharts() function to force a reload of all charts? Maybe that will help.

  7. Is it possible to have a Dual Y axis on a bar chart? (not a column chart)

     

     

     

    I need a chart to display 2 data series as a horizontal bar (GoodQty (circa 20,000) and Scrap (circa 20))

     

    The MSBar2D.swf allows 2 data series but not separate min-max axis settings.

     

     

     

    Many thanks,
