<H2><A NAME="10_5">10.5 Creating a GanttChart</A></H2>
|
|
|
29 |
<P> You create a new Gantt Chart with a call to GanttChart(). The
|
|
|
30 |
signature for GanttGraph is the same as for ordinary JpGraph graphs,
|
|
|
31 |
i.e<DIV class="phpscript"><CODE><FONT color="#000000"> <FONT color="#0000BB">
|
|
|
32 |
</FONT><FONT color="#007700">function </FONT><FONT color="#0000BB">
|
|
|

|
|

|
|
|
36 |
$aCachedName</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">
|
|
|
37 |
$aTimeOut</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">
|
|
|
38 |
$aInline</FONT><FONT color="#007700">)</FONT><FONT color="#0000BB"></FONT>
|
|
|
39 |
</FONT></CODE></DIV></P>
|
|
|
40 |
<P>The only real difference is that for GanttCharts you can specify one
|
|
|
41 |
or both of the dimension parameters (width and height) as -1 in which
|
|
|
42 |
case that dimension will be automatically sized determined by scale and
|
|
|
43 |
fonts chosen. The following examples shows some possible ways of
|
|
|
44 |
creating a new graph</P>
|
|
|
45 |
<UL>
|
|
|
46 |
<LI> $graph=new GanttGraph()
|
|
|
47 |
<BR> The size of the graph will be determined automatically, no caching
|
|
|
48 |
will be used and the graph will be generated in-line.</LI>
|
|
|
49 |
<LI> $graph=new GanttGraph(-1,-1,"auto")
|
|
|
50 |
<BR> The size of the graph will be determined automatically, caching
|
|
|
51 |
will be used (the name will be based on the script name), no timeout
|
|
|
52 |
will be used and the graph will be generated in-line</LI>
|
|
|
53 |
<LI> $graph=new GanttGraph(450,-1,"auto",5)
|
|
|
54 |
<BR> Same as the previous entry but the width is fixed to 450 points and
|
|
|
55 |
the cached image will have a timeout of 5 min.</LI>
|
|
|
56 |
<LI> $graph=new GanttGraph(-1,-1,"auto",5,false)
|
|
|
57 |
<BR> The image will not be generated in-line, only the cache will be
|
|
|
58 |
updated if it has timed out, otherwise nothing will happen.</LI>
|
|
|
59 |
</UL>
|
|
|
60 |
<P> Since GanttGraph() inherits all the methods (that make sense for
|
|
|
61 |
GanttGraph) from Graph you can specify shadow, color etc of the general
|
|
|
62 |
frame.</P>
