Help needed - Advanced Chart Coding

Question

Hi all,
I am currently developing some charts that have to be coded as wizard is not enough for this. Any idea where to find some advanced chart coding for using random colors for bars and adding values on top of bars, etc.
This is my current code that I need to extend:
chart:
<Graph depthAngle="50" depthRadius="8" pieDepth="30" pieTilt="20" seriesEffect="SE_AUTO_GRADIENT" graphType="BAR_VERT_CLUST">
<LegendArea visible="true" />
<LocalGridData colCount="3" rowCount="1"><RowLabels>
<MarkerText visible="true" markerTextPlace="MTP_CENTER"/>
<Label>Number of Hours</Label>
</RowLabels>
<ColLabels>
<xsl:for-each select="current-group()" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:if test="../@name='Hours_Demand_Daily'or ../@name='Hours_Scheduled_Daily' or ../@name='Hours_Budget_Daily'">
<Label>
<xsl:value-of select="translate(../@name,'_',' ')"/>
</Label>
</xsl:if>
</xsl:for-each>
</ColLabels>
<DataValues>
<RowData>
<xsl:for-each select="current-group()" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:if test="../@name='Hours_Demand_Daily'or ../@name='Hours_Scheduled_Daily' or ../@name='Hours_Budget_Daily'">
<Cell>
<xsl:value-of select="ows:Quantity"/>
</Cell>
</xsl:if>
</xsl:for-each>
</RowData>
</DataValues>
</LocalGridData>
</Graph>
