<H2><A NAME="2_3">2.3 JpGraph Features</A></H2>
|
|
<P> JpGraph library is an OO graph library which makes it easy to both
|
|
draw a "quick and dirty" graph with a minimum of code and quite complex
|
|
graphs which requires a very fine grain of control. The library tries
|
|
to assign sensible default values for most parameters hence making the
|
|
learning curve quite flat since for most of the time very few commands
|
|
is required to draw graphs with a pleasing esthetic look.</P>
|
|
<P> Some highlights of available features are</P>
|
|
<UL>
|
|
<LI> Flexible scales, supports text-lin, text-log, lin-lin, lin-log,
|
|
log-lin and log-log and integer scales.</LI>
|
|
<LI> Supports both PNG, GIF and JPG graphic formats. Note that the
|
|
available formats are dependent on the specific PHP installation where
|
|
the library is used.</LI>
|
|
<LI>Supports caching of generated graphs to lessen burden of a HTTP
|
|
server.</LI>
|
|
<LI> Supports batch mode to only generate images to a file</LI>
|
|
<LI>Supports client side image maps which makes it easy to produce drill
|
|
down images.</LI>
|
|
<LI>Intelligent auto-scaling which gravitates towards esthetic values,
|
|
i.e. multiples of 2:s and 5:s</LI>
|
|
<LI>Fully supports manual scaling, with fine grain control of position
|
|
of ticks.</LI>
|
|
<LI>Supports background images with different formatting options</LI>
|
|
<LI>Supports color and brightness adjustments of images directly in PHP.</LI>
|
|
<LI>User specified grace for auto-scaling</LI>
|
|
<LI> Supports up to two different y-scale, it is possible to have
|
|
different left and right y-scale and add plots to both</LI>
|
|
<LI>Supports, line-plots, filled line-plots, accumulated line-plots, bar
|
|
plots, accumulated bar plots, grouped bar plots, error plots, line
|
|
error plots, scatter plots, gantt-charts, radar plots, 2D and 3D pie
|
|
charts.</LI>
|
|
<LI>Supports unlimited number of plots in each graph, makes it easy to
|
|
compose complex graph which consists of several plot types</LI>
|
|
<LI>User specified position of axis</LI>
|
|
<LI>Supports color gradient fill in seven styles</LI>
|
|
<LI>Designed as a flexible OO framework which makes it easy to add new
|
|
types of plots</LI>
|
|
<LI>Supports automatic legend generation</LI>
|
|
<LI>Supports both vertical and horizontal grids</LI>
|
|
<LI>Supports anti-aliasing of lines</LI>
|
|
<LI>Supports background images as well as unlimited number of icons in
|
|
the graph</LI>
|
|
<LI>Supports rotation of linear graphs</LI>
|
|
<LI>More then 400 named colors</LI>
|
|
<LI>Designed modularly - you don't have to include code which isn't used</LI>
|
|
<LI> ...and many many more features</LI>
|
|
</UL>
|
|
<P> In addition to these high level features the library has been
|
|
designed to be orthogonal and consistent in its' naming convention. For
|
|
example, to specify color each object (i.e. axis, grids, texts, titles
|
|
etc) within the graph implements the method SetColor() with the same
|
|
signature.</P>
