  28  <H3><A NAME="9_2_7">9.2.7 Another variant of 2D Pie plots</A></H3>
  29  <P> As mentioned in the beginning there are two versions of the 2D pie
  30   plots. The normal pie plot created as an instance of <A href="../ref/PiePlot.html#_C_PIEPLOT">
  31   class PiePlot</A> and a variant created as an instance of <A href="../ref/PiePlot.html#_C_PIEPLOTC">
  32   class PiePlotC</A></P>
  33  <P> This variant is an extension of the standard PiePlot in the sense
  34   that it also have a filled circle in the center. The following example
  35   illustrates this</P>
  36  <P><DIV class="example">
  37  <BR> <A href="exframes/frame_piecex1.html" target="blank"><IMG border="0"
  38  HEIGHT="300"  src="img/piecex1.png" WIDTH="300"></A>
  39  <BR><B>Figure 133:</B> Example of the variant of pie plot with a filled
  40   center circle <A href="exframes/frame_piecex1.html" target="blank">
  41  [src]</A>&nbsp;
  42  <P></P>
  43  </DIV></P>
  44  <P></P>
  45  <P> Since the PiePlotC is an extension to the basic pie plot all the
  46   normal formatting you can do for pie plots you can also do for the
  47   PiePlotC .</P>
  48  <P> The additional formatting only concerns the filled middle circle.
  49   You have the option of adjusting size, fill color and all font
  50   properties. You perform these operations with the methods</P>
  51  <P></P>
  52  <TABLE>
  53  <TR><TD><A href="../ref/PiePlotC.html#_PIEPLOTC_SETMIDCOLOR">
  54  PiePlotC::SetMidColor()</A></TD><TD>Set fill color of mid circle</TD></TR>
  55  <TR><TD><A href="../ref/PiePlotC.html#_PIEPLOTC_SETMIDSIZE">
  56  PiePlotC::SetMidSize()</A></TD><TD>Set size (fraction of radius)</TD></TR>
  57  <TR><TD><A href="../ref/PiePlotC.html#_PIEPLOTC_SETMIDTITLE">
  58  PiePlotC::SetMidTitle()</A></TD><TD>Set title string (may be
  59   multi-lined)</TD></TR>

  61  PiePlotC::SetMid()</A></TD><TD>Set all parameters in a single method
  62   call</TD></TR>
  63  </TABLE>
  64  <P> In addition to the normal CSIM for PiePlot:s the center area is also
  65   a CSIM hotspot. You specify the target CSIM with a call to <A href="../ref/PiePlotC.html#_PIEPLOTC_SETMIDCSIM">
  66   PiePlotC::SetMidCSIM()</A></P>
  67  <P> The next example shows an example with some more innovative
  68   formatting. In this example we have :</P>
  69  <UL>
  70  <LI> hidden the frame around the pie graph</LI>
  71  <LI> exploded all the slices</LI>
  72  <LI> added drop shadow to the individual slices (and the center filled
  73   circle)</LI>
  74  <LI> specified individual multi line labels.</LI>
  75  <LI> changed the font for the title to a TTF font.</LI>
  76  </UL>
