Relatime charts-update last point

Recommended Posts

Hi,

 

     In realtime charts, is there a way to update the last point in the chart, instead of adding a new point?I mean will we be able to specify , while sending a new point,whether we want to use that point to update the last point , or it should be added as a new point.

 

Thanks,

Deepthy.

Hi Deepthy,

 

In FusionWidgets XT Real-Time charts, the data provider page will fetch the new data from the web services or databases and push to the chart as new data points, on each page request.

 

So, the feature of updating only the last data point keeping rest of the data points unchanged, is not supported in Real-Time charts, as of now.

 

However, as a work around, using the feature of "Passing multiple data in each update", you could fulfill your requirement, by sending the entire set of data with the last data point changed, on each update.

 

For more information on "Real-time data format", please visit the online documentation link: http://docs.fusioncharts.com/widgets/Contents/?DataStreaming/Format.html

 

Hope this helps!

Thanks a lot for the reply.I will try this out.

I have one more doubt.Can we add the drilldown js function (js function to be invoked on click of this point in the chart) also to the realtime data points ?

Can you please give me an example for the same?

 

Thanks,

Deepti.

Hi Deepti,

 

Yes, you can provide your drill-down JavaScript function link to the each incremental data, through the data provider page.

 

For more information on "Real-time data format > Providing link for each incremental data", please visit the link: http://docs.fusioncharts.com/widgets/Contents/DataStreaming/Format.html

 

Also, for plotting multi-series line chart, the same SWF file "RealTimeLine.swf" could be used with multiple data sets in the XML file.

 

For more information on "Real-Time Line Chart Specification Sheet", please visit the link: http://docs.fusioncharts.com/widgets/Contents/DataStreaming/XMLRealTimeLine.html

 

Hope this helps!
