hard to create. I looked at the code from this site and started creating my own variations for testing.
http://www.svgopen.org/2003/papers/CreatingSVGPieChartsThroughWebService
Here is a Pie Chart that I tested with:
<fo:table-cell xsl:use-attribute-sets="table-piechart-style">
<xsl:variable name="number" select="operatingaverages/monthly/efficiency" />
<xsl:variable name="difference" select="100 - $number" />
<xsl:variable name="currentAngle" select="math:toRadians(($number div 100) * 360.0)" />
<xsl:variable name="halfAngle" select="math:toRadians((($number div 2) div $total) * 360.0)" />
<xsl:variable name="rotation" select="270 + (360.0 * ($number div 100))" />
<xsl:variable name="x1" select="math:cos($halfAngle) * 70" />
<xsl:variable name="y1" select="math:sin($halfAngle) * 70" />
<xsl:variable name="cosTheta" select="math:cos(math:toRadians($rotation))" />
<xsl:variable name="sinTheta" select="math:sin(math:toRadians($rotation))" />
<fo:instream-foreign-object>
<svg height="100" viewBox="0 0 200 100" width="200" xmlns="http://www.w3.org/2000/svg"; xmlns:xlink="http://www.w3.org/1999/xlink";>
<g>
<path style="fill:{$color1};stroke:black;stroke-width:1;fillrule:evenodd; stroke-linejoin:bevel;">
<xsl:attribute name="transform">
<xsl:text>translate(100,50)</xsl:text>
<xsl:text>rotate(</xsl:text>
<xsl:value-of select="$rotation" />
<xsl:text>)</xsl:text>
</xsl:attribute>
<xsl:attribute name="d">
<xsl:text>M 50 0 A 50 50 0 </xsl:text>
<xsl:choose>
<xsl:when test="$currentAngle > 3.14">
<xsl:text>1 </xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>0 </xsl:text>
</xsl:otherwise>
</xsl:choose>
<xsl:text>1 </xsl:text>
<xsl:value-of select="math:cos($currentAngle) * 50" />
<xsl:text> </xsl:text>
<xsl:value-of select="math:sin($currentAngle) * 50" />
<xsl:text> L 0 0 Z</xsl:text>
</xsl:attribute>
</path>
</g>
</svg>

hi,
i'm using FOP for our reporting tools, thanks to FOP we can make a nice looking PDF-File. great job people !
recently we need to generate not only tables or text, but also some
charts/diagramms ( like pie chart, gantt , etc)
and this charts should be embeded in the pdf, as a graphic format ( like SVG
or JPEG )
Does anyone have any idea how to do these things ? somekind of library maybe
?
thanks in advance
sandy
