<H3><A NAME="7_1_2">7.1.2 Displaying the values for each data point</A></H3>
<P> As a final easy modification we can enable the display of the data
 value above each data point. The value is represented by the 'value'
 property in the plot. (You can read more about the possibilities of the
 <A href="../ref/DisplayValue.html#_C_DISPLAYVALUE"> display value</A>
 in the class reference.)</P>
<P> To enable the display of the value you just need to call the Show()
 method of the value as in<DIV class="phpscript"><CODE><FONT color="#000000">
 <FONT color="#0000BB">&nbsp;$lineplot</FONT><FONT color="#007700">-&gt;</FONT><FONT
color="#0000BB">value</FONT><FONT color="#007700">-&gt;</FONT><FONT color="#0000BB">
Show</FONT><FONT color="#007700">()</FONT><FONT color="#0000BB"></FONT></FONT>
</CODE></DIV></P>
<P> Adding that line to the previous line plot would give the result
 shown below.<DIV class="example">
<BR> <A href="exframes/frame_example3.3.html" target="blank"><IMG border="0"
HEIGHT="200"       src="img/img/img/img/img/img/example3.3.png" WIDTH="300"></A>
<BR><B>Figure 8:</B> Displaying the value for each data point <A href="exframes/frame_example3.3.html"
target="blank">[src]</A>&nbsp;
<P></P>
</DIV></P>
<P> We can of course change both color, font and format of the displayed
 value. So for example if we wanted the display values to be dark red,
 use a bold font and have a '$' in front we need to add the lines<DIV class="phpscript">
<CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;$lineplot</FONT><FONT
color="#007700">-&gt;</FONT><FONT color="#0000BB">value</FONT><FONT color="#007700">
-&gt;</FONT><FONT color="#0000BB">SetColor</FONT><FONT color="#007700">(</FONT><FONT
color="#DD0000">&quot;darkred&quot;</FONT><FONT color="#007700">);
<BR></FONT><FONT color="#0000BB">$lineplot</FONT><FONT color="#007700">
-&gt;</FONT><FONT color="#0000BB">value</FONT><FONT color="#007700">-&gt;</FONT><FONT
color="#0000BB">SetFont</FONT><FONT color="#007700">(</FONT><FONT color="#0000BB">
FF_FONT1</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">
FS_BOLD</FONT><FONT color="#007700">);
<BR></FONT><FONT color="#0000BB">$lineplot</FONT><FONT color="#007700">
-&gt;</FONT><FONT color="#0000BB">value</FONT><FONT color="#007700">-&gt;</FONT><FONT
color="#0000BB">SetFormat</FONT><FONT color="#007700">(</FONT><FONT color="#DD0000">
&quot;$&nbsp;%0.1f&quot;</FONT><FONT color="#007700">);</FONT><FONT color="#0000BB"></FONT>
</FONT></CODE></DIV></P>
<P> This would then result in the following image<DIV class="example">
<BR> <A href="exframes/frame_example3.4.html" target="blank"><IMG border="0"
HEIGHT="200"       src="img/img/img/img/img/img/example3.4.png" WIDTH="300"></A>
<BR><B>Figure 9:</B> Making the display values a little bit more
 interesting <A href="exframes/frame_example3.4.html" target="blank">
[src]</A>&nbsp;
<P></P>
</DIV></P>
<P><DIV class="note"><B>Note:</B> You can achieve more advanced
 formatting by using not just the printf() style format string by a
 format callback function. This could allow you to change the displayed
 value with more advanced formatting such as displaying money values
 with &quot;,&quot; to separate thousands.</DIV></P>
