Text comments on line chart

Question

Hi,
I have a single series flash chart displaying dates on X axis and some values on Y axis. The data comes from a table defined as
Week_Start DATE;
Production_Level NUMBER;
Txt_Comment VARCHAR2(255);
Some data points have textual comments attached to them (e.g. explanations for unusually high/low production levels) and I wouold like to display them beside the associated points.
Any ideas on how this can be done would be welcome...
I use APEX 3.0 with AnyChart 5.1.2 and Oracle 10g
Many thanks,
Constantine

Hi Sergio,
Thank you for your help.
This looks promising, except I can't get it to work - would you please take a look at the code I have and let me know what I am doing wrong?
Here is what my PL/SQL returns and this gets assigned to a hidden page item called P1_TMP_CHART_DATA:
<data>
<series name="Series 1">
<point name="Jan 01" y="0">
<attributes>
<attribute name="comment"><!CDATA[NONE]]></attribute>
</attributes>
</point>
<point name="Jan 08" y="96">
<attributes>
<attribute name="comment"><!CDATA[NONE]]></attribute>
</attributes>
</point>
</series>
</data>and here is the XML I have for my chart:
<?xml version = "1.0" encoding="utf-8" standalone = "yes"?>
<anychart>
<margin all="1"/>
<settings>
<animation enabled="false"/>
</settings>
<charts>

    <marker type="Circle" />
  </marker_settings>
</line_series>
</data_plot_settings>
&P1_TMP_CHART_DATA.
</chart>
</charts>
</anychart>Now, the problem is that when I run my page, I get the chart container with a message saying "XML parser failure: The element type must be terminated by the matching end-tag."
If I replace &P1_TMP_CHART_DATA. in my XML with #DATA# I get to see the chart with some sample data points, so I am guessing the XML itself (axes, title, etc) is probably OK and I messed something up in the definition of &P1_TMP_CHART_DATA.
Your help would be most appreciated.
Thanks,
Constantine
