Question

Hi, I tried to create a chart some dificult for me.
This is my chart that is generate with rtf.

And this is my code chart.
chart:
<Graph seriesEffect="SE_AUTO_GRADIENT" graphType="BAR_VERT_STACK">
<LegendArea visible="true" />
<SeriesItems>
<Series id="0" markerType="MT_BAR" color="#ff0000"/>
<Series id="1" markerType="MT_BAR" color="#99ccff"/>
</SeriesItems>
<LocalGridData colCount="{count(xdoxslt:group(current-group(), 'Proceso'))}" rowCount="2">
<RowLabels><Label>A</Label><Label>B</Label></RowLabels>
<ColLabels><xsl:for-each-group select="current-group()" group-by="Proceso" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:sort select="current-group()/Proceso" />
<Label>
<xsl:value-of select="current-group()/Proceso"/>
</Label>
</xsl:for-each-group>
</ColLabels>
<DataValues>
<RowData>
<xsl:for-each-group name="Var1" select="current-group()" group-by="Proceso" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:sort select="current-group()/Proceso" />
<Cell>
<xsl:value-of select="sum(current-group()/Valor_proceso)" />
</Cell>
</xsl:for-each-group>
</RowData>
<RowData>
<xsl:for-each-group select="current-group()" group-by="Proceso" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:sort select="current-group()/Proceso" />
<Cell>
<xsl:value-of select="sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso)" />
</Cell>
</xsl:for-each-group>
</RowData>
</DataValues>
</LocalGridData>
</Graph>
Well.
If you read I substract two values into chart: <xsl:value-of select="sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso)" />
When the result is positive the bar is correct, but when the result is negative the bar is incorrect because 'B' Value is under zero, I know it is normal but I don´t want this.
This Image generate with MsPaint is result correct for all bars

Finally I think a idea but I don´t know it is possible.
This is my posible solution:
1.- For example the case is negative:
Can I write conditional Ifs into xsl:value-of select and how?
<?if:number(sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso))<0?>sum(Valor_proceso)+sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso)<?end if?>
<?if:number(sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso))>0?>sum(current-group()/Valor_proceso_Aragon)-sum(Valor_proceso)<?end if?>
<xsl:value-of select="<?if:number(sum(current-group()/30)-sum(40))<0?>sum(40)+sum(current-group()/30)-sum(40)<?end if?>" />
The result is negative but thaks the conditionals now I have a positive result, for example 30(B) becasuse A=40.
2.-And after I configurate chart for paint transparent bar by "B" and outline bar by B, black.
Do you understand me? It is very dificult.
Thanks.

Carlos,
I few weeks back you found a solution to a chart issue the yo were having. I am currently having the same issue. Can you share the code for your chart?
