<H3><A NAME="7_1_1">7.1.1 Adding plot marks to line-plots XXX</A></H3>
|
|
|
29 |
<P> It might sometimes be desirable to highlight the data-points with
|
|
|
30 |
marks in the intersection between the given x and Y-coordinates. This
|
|
|
31 |
is accomplished by specifying the wanted plot mark type for the "mark"
|
|
|
32 |
property of the line graph. A full list of all available marks is given
|
|
|
33 |
in the class reference <A href="../ref/PlotMark.html#_PLOTMARK_SETTYPE">
|
|
|
34 |
PlotMarks</A></P>
|
|
|
35 |
<P> For now let's just add a triangle shape marker to our previous graph
|
|
|
36 |
by adding the line<DIV class="phpscript"><CODE><FONT color="#000000"> <FONT
|
|
|
37 |
color="#0000BB"> $lineplot</FONT><FONT color="#007700">-></FONT><FONT color="#0000BB">
|
|
|
38 |
mark</FONT><FONT color="#007700">-></FONT><FONT color="#0000BB">SetType</FONT><FONT
|
|
|
39 |
color="#007700">(</FONT><FONT color="#0000BB">MARK_UTRIANGLE</FONT><FONT color="#007700">
|
|
|
40 |
);</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV></P>
|
|
|
41 |
<P> This will give the graph as shown below<DIV class="example">
|
|
|
42 |
<BR> <A href="exframes/frame_example3.1.html" target="blank"><IMG border="0"
|
|
|
43 |
HEIGHT="200" src="img/img/img/img/img/img/example3.1.png" WIDTH="300"></A>
|
|
|
44 |
<BR><B>Figure 7:</B> Adding markers to the previous example <A href="exframes/frame_example3.1.html"
|
|
|
45 |
target="blank">[src]</A>
|
|
|
46 |
<P></P>
|
|
|
47 |
</DIV></P>
|
|
|
48 |
<P></P>
|
|
|
49 |
<P> If you like you can of course both change the size, fill-color and
|
|
|
50 |
frame color of the chosen plot mark.</P>
|
|
|
51 |
<P> The colors of the marks will, if you don't specify them explicitly,
|
|
|
52 |
follow the line color. Please note that if you want different colors
|
|
|
53 |
for the marks and the line the call to SetColor() for the marks must be
|
|
|
54 |
done after the call to the line since the marks color will always be
|
|
|
55 |
reset to the lines color when you set the line.</P>
