vLines not showing up (RealTimeLine.swf) when added as part of real-time data stream.

[badf00d]

According to the widgets documentation, the following realtime data should create a

 

vLine:

 

&label=11:45&value=753|345&vline=0&vLineLabel=vLine&vLineColor=666666&vLineThickness=2&vLineDashed=1

 

However it does not do so on the RealTimeLine.swf chart I have created. The chart is

 

loaded with historical data and then fed realtime data. vLines are placed on the start of

 

each hour. The lines show up properly when added as part of the historical feed, but do

 

not show up when added as part of the realtime feed using the format provided.

 

This is the chart setup:

 

 

 

var chart = new FusionCharts("../FusionWidgets/Charts/RealTimeLine.swf", "ChartId", "720", "468", "0", "0");

chart.setDataURL("DataRTSnap.asp?<%= Replace(Request.QueryString, "&", "%26") %>");		   

chart.render("chartdiv");

 

This is a sample of the chart xml returned from DataRTSnap.asp (which correctly places a vLine at the hour):

 

 

 

<chart legendPosition='RIGHT' forceDecimals='1' caption='Test'

xAxisName='Time' yAxisName='Value' divLineAlpha='20' numdivlines='5' showValues='0'

formatNumberScale='0' labelDisplay='ROTATE' slantLabels='1' 

showAlternateVGridColor='0' alternateHGridAlpha='12' animation='1' divLineDecimalPrecision='2' setAdaptiveYMin='1'

xAxisNamePadding='0' showRealTimeValue='0' realTimeValuePadding='0'

numDisplaySets='120' labelPadding='5' yAxisValuesPadding='15' numVdivlines='0'

dataStreamURL='DataRT.asp' refreshInterval='20' dataStamp='7.30.2008T11!05'>

<categories>

<category label='7-30 10:58'/>

<category label='7-30 10:59'/>

<vLine alpha='20' thickness='1'/>

<category label='7-30 11:00'/>

<category label='7-30 11:05'/>

</categories>

<dataset seriesName='Set1' includeInLegend='1' showValues='0' color='FF0000' lineThickness='1' anchorRadius='0'>

<set value='2.76'/>

<set value='2.76'/>

<set value='2.76'/>

<set value='2.76'/>

</dataset>

<dataset seriesName='Set2' includeInLegend='1' showValues='0' color='008000' lineThickness='1' anchorRadius='1'>

<set value='10.584'/>

<set value='10.656'/>

<set value='10.584'/>

<set value='10.656'/>

</dataset>

<dataset seriesName='Set3' includeInLegend='1' showValues='0' color='12228D' lineThickness='1' anchorRadius='0'>

<set value='10.78'/>

<set value='10.78'/>

<set value='10.77'/>

<set value='10.77'/>

</dataset>  

</chart>

 

This is a sample off the data returned from DataRT.asp (which does not place a vLine on the chart):

 

 

 

&label=7-30 11:06&value=2.76|10.34|10.78&vline=0&vLineLabel=vLine&vLineColor=666666&vLineThickness=2&vLineDashed=1&dataStamp7.30.2008T11!06

 

So, something is wrong....help would be appreciated.

 

 

 

Thanks.

fyi...I answered my own question...the example in the docs is incorrect.

For anyone else who is interested and for posterity sake. I fixed the issue by change the vLine value from 0 to 1

i.e.,

&label=7-30 11:06&value=2.76|10.34|10.78&vline=1&vLineLabel=vLine&vLineColor=666666&vLineThickness=2&vLineDashed=1&dataStamp7.30.2008T11!06
