<p>OS BIRT or commercial BIRT? Which version?</p>

<p>Having done some searching, I've found that support for series labels is not as commonplace as I expected. The standard method is to use a legend to identify different series. Even the HighCharts API doesn't include a series label. I found an example online that makes use of a trick in code to achieve this functionality in Highcharts. That solution works in commercial BIRT with a little coding. If you're using Open Source BIRT, it doesn't support Highcharts. There is a script tab to add custom Java and JavaScript code that modifies the chart. I don't have an example of how to implement a series label in Open Source BIRT. If I come across one I'll post it.</p>

<p>If you are using OS BIRT, you can use this technique outlined in this DevShare (<a data-ipb='nomediaparse' href='
http://developer.actuate.com/community/forum/index.php?/files/file/1086-bar-chart-with-dynamic-markerthreshold-lines/'>http://developer.actuate.com/community/forum/index.php?/files/file/1086-bar-chart-with-dynamic-markerthreshold-lines/</a>)
to draw a transparent marker line and add text to it. </p>
<p> </p>
<p>Attached is a sample that works both in OS BIRT and commercial BIRT.</p>
<p> </p>
<p>If you are using commercial BIRT, you can take advantage of the HighCharts script that is available and you'll have more options available to manipulate the HTML5 charts.</p>
<p> </p>
<p>Another attached sample (specifically for commercial BIRT) uses the plotLines on the Y Axis (<a data-ipb='nomediaparse' href='
; Using HighCharts options, we add two plotlines, one for each series and add a label. We also modify the markers so that we have a non-filled circle like the screenshot. </p>
<p> </p>
<p>Other options in commercial BIRT to add those labels, as Jeff mentioned requires little coding. Those other techniques use the HighCharts Renderer (<a href="
http://api.highcharts.com/highcharts#Renderer">http://api.highcharts.com/highcharts#Renderer</a>)
or HighCharts <a>dataLabels(
http://api.highcharts.com/highcharts#plotOptions.series.dataLabels). </a>
; JSFiddles from Jeff that illustrate these two techniques, respectively (via Renderer @ <a data-ipb='nomediaparse' href='
http://jsfiddle.net/TkRXA/'>http://jsfiddle.net/TkRXA/</a>
; or via datalabels @ <a data-ipb='nomediaparse' href='
http://jsfiddle.net/gK52f/1/).'>http://jsfiddle.net/gK52f/1/).</a>

<p>Thank you Clement.</p>
<p>You've been very helpful with your samples.</p>
