Get yourself Organized!

A request from Leslie today to help her out on the user docs. In them we state that we support the MSWord organization charts but we do not give any detail.

Use the organization chart functionality in the templates and the chart that is rendered in the output. Figure 4-18 shows an example of an organization chart.

Figure 4-18 Sample Organization Chart

Description of Figure 4-18 follows

Its been a  while since I have looked at them but we mean just that. You build an org chart with names in the boxes, BIP will render it, simple.

Oh, you wanted it to load the names into the chart dynamically from the dataset? Sorry, no dice, at least not with the MSWord Org Chart object.

However, you can create your own org chart structure using MSShapes and use BIP's ability to fill those shapes with text from your data. Thats documented pretty well and is very easy to do. Taking it to obvious final step; completely data driven org chart structure and text. Thats a bit tougher. It can be done with the shape copy and move commands but its going to take some planning. You need to think about how wide your 'page' is, what to do when you reach the edge and need to continue with the same level in the hierarchy, etc.

To get you started, I have created a sample template and data for the first two scenarios. They will work with all releases of BIP and XMLP. The third will take me a little longer :0)

Conditional Charting II

A follow up post on yesterdays efforts. After pinging a few colleagues Klaus came up with a much much neater approach that appeals to my sense of easy, straightforward and neat, when it comes to code anyway. A by product of the approach, it can handle, none, one or multiple conditonal bars.

So, no variables ... a big plus, some chart xml editing, not quite so good but the benefits far outweigh the costs. Its a case of digging into the chart code and maybe Klaus (who is in charge of the template builders) will one day, provide this conditionality via the chart dialogs ... pleeeease Klaus :0)

Heres the relevant snippet of the chart code:

<Graph seriesEffect="SE_AUTO_GRADIENT">
 <LegendArea visible="false" />
 <ExceptionalRisers>
  <xsl:for-each select=".//Row"  xmlns:xsl="
http://www.w3.org/1999/XSL/Transform">
  <xsl:if test="number(number(.//Value) div number(.//Target))&lt; number($pLim)">
   <ExceptionalRiser series="0" group="{position()-1}" fill border/> 
  </xsl:if>
  </xsl:for-each>
 </ExceptionalRisers>
 <LocalGridData>
...
</Graph> 

We essentially, build the multiple ExceptionalRiser entries in the graph code itself rather than try and build out a concatentated string variable. The string approach was my first thought but 1. XSL does not allow XML strings to be built dynamically and 2. the chart does not break if there are no conditional columns to be rendered.
Dealing with the code a line at a time
  <xsl:for-each select=".//Row"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
Loop over the data as we did before
  <xsl:if test="number(number(.//Value) div number(.//Target))&lt; number($pLim)">
Look for percentages less than a specified value. I externalized this value into a variable (pLim) to make things easier to test, you can play with it in the template.
   <ExceptionalRiser series="0" group="{position()-1}" fill border/> 
If we find a row of data that meets the criteria we create an ExceptionalRiser entry and use the current record number (position()) minus 1 because out bars are numbered from zero.
Then we just close out the if, the for-each and we're done.
If the if statement does not return true at all i.e. no bars need to be colored; the chart just renders as normal, nice!

Klaus took his example a little further than mine. The one thing that my approach suffers from is that it requires the engine to loop over the data twice for the chart. Once to search for ExceptionalRisers and again to render the chart itself. Klaus took an aproach to create a variable to hold the chart data first and then  run the riser code and chart rendering against that. Check that out in the second template (ConditionalChart2-1.rtf) please note, that its an 11g template and will need the 11g plugin to see it running. Both available and with sample datasets here.

You can now conditionally color your bar charts, horizontal or vertical. I have tried the same with pie charts but no banana so I'm assuming its only going to work for bar charts. I have tested on 10.1.3.4.x and 11g releases.

More Charting Tips

Too many questions on the love of my life, BIP charts. Oh the joy of finding out how to add a trendline or a fixed horizontal line, the list goes on. Its quite easy really but that's because I have an internal chart rendering tool that generates the XML I need to do cool stuff in charts. Some times I have to resort to scouring the chart DTD but the tool lets me test the feature I want. Sadly, the tool is not owned by BIP so we do not have the authority to make it public but I so wish it were. It would help you to help yourselves sooo much.

Two things to cover today ...

X Axis Labels

 

I've a Bar chart where X-axis labels are coming as horizontally-alligned and one value above, next value in a level below...so on.
Is it possible change the alignment to -45 degree as it is available in excel chart? x-axis data label points will be displayed in uniform way then.

 

45 degrees is not possible at the moment. you can get them to show at 90 or 270 degrees thou

 

<O1TickLabel textRotation="TR_HORIZ_ROTATE_90" automaticRotation="AR_NO_ROTATE"/>

 

you can influence other properties too

 

<O1TickLabel textRotation="TR_HORIZ_ROTATE_90" automaticRotation="AR_NO_ROTATE">

There was a followup kindly answered by Vetsrini

Fixed Axis Scale

Is it possible to define a fixed scale for x-axis? I see by default Bipublisher decides scale based on the value coming from dataset. I want to set scale always from 0 to 500 with label showing at interval of 10. 
<X1Axis axisMinAutoScaled="false" axisMinValue="0" axisMaxAutoScaled="false" 
axisMaxValue="500" majorTickStepAutomatic="false" majorTickStep="10"/>

 and then,
Static Chart Line

How do I show a static line on my chart?

 Vetsrini and I seemed to be in a race to answer charting questions yesterday :0)

Inside the Graph tag use: 

<Y1ReferenceLine>
<ReferenceLine index="0" visible="true" lineWidth="2" text="My Ref Line" value="550.0" displayedInLegend="true" lineColor="#3366ff"/>
</Y1ReferenceLine>

and finally

Trend Lines

 Does BIP have the ability to create trend/regression lines?

 Yep, it does, manual job like the others above but possible.
Under the Graph tag 

<SeriesItems defaultFitlineType="FT_LINEAR"/>

 Valid vaues for fitlinetype are FT_LINEAR|FT_LOGARITHMIC|FT_EXPONENTIAL

if you want multiple lines fitted to data points

<SeriesItems>
<Series id="0" fitlineType="FT_LOGARITHMIC"/>
<Series id="1" fitlineType="FT_EXPONENTIAL"/>
</SeriesItems>


  

I'll blog em as they come in and we manage to answer them. Happier charting!
