Sketsa SVG Editor 6.0 (Default branch)
11-25-2008
Sketsa SVG Editor is a vector drawing applicationbased on SVG. It allows users to create vectorgraphics that can be scaled and printed at anyresolution, without losing detail or clarity. Itfeatures various tools for optimizing contentcreation, and includes a property palette, a DOMeditor, a source editor, a resource editor,SVG-specific shape tools, transformation tools,and additional illustration tools. It uses SVG asits native file format.License: Other/Proprietary License with Free TrialChanges:|

Graph(3pm) User Contributed Perl Documentation Graph(3pm) NAME
SVG::Graph - Visualize your data in Scalable Vector Graphics (SVG) format. SYNOPSIS
use SVG::Graph; use SVG::Graph::Data; use SVG::Graph::Data::Datum; #create a new SVG document to plot in... my $graph = SVG::Graph->new(width=>600,height=>600,margin=>30); #and create a frame to hold the data/glyphs my $frame = $graph->add_frame; #let's plot y = x^2 my @data = map {SVG::Graph::Data::Datum->new(x=>$_,y=>$_^2)} (1,2,3,4,5); my $data = SVG::Graph::Data->new(data => @data); #put the xy data into the frame $frame->add_data($data); #add some glyphs to apply to the data in the frame $frame->add_glyph('axis', #add an axis glyph 'x_absolute_ticks' => 1, #with ticks every one #unit on the x axis 'y_absolute_ticks' => 1, #and ticks every one #unit on the y axis 'stroke' => 'black', #draw the axis black 'stroke-width' => 2, #and 2px thick ); $frame->add_glyph('scatter', #add a scatterplot glyph 'stroke' => 'red', #the dots will be outlined #in red, 'fill' => 'red', #filled red, 'fill-opacity' => 0.5, #and 50% opaque ); #print the graphic print $graph->draw; DESCRIPTION
SVG::Graph is a suite of perl modules for plotting data. SVG::Graph currently supports plots of one-, two- and three-dimensional data, as well as N-ary rooted trees. Data may be represented as: Glyph Name Dimensionality supported 1d 2d 3d tree -------------------------------------------------------- Axis x Bar Graph x Bubble Plot x Heatmap Graph x Line Graph x Pie Graph x Scatter Plot x Spline Graph x Tree x SVG::Graph 0.02 is a pre-alpha release. Keep in mind that many of the glyphs are not very robust. PLOTTING
You need to create a SVG::Graph::Frame instance from the parent SVG::Graph instance for each set of data to be plotted. Datasets can be hierarchical, and to represent this, SVG::Graph::Frame instances can themselves contain subframes. SVG::Graph::Frame can contain: - multiple subframes as instances of SVG::Graph::Frame - a single SVG::Graph::Data instance - multiple SVG::Graph::Glyph instances with which to render the attached SVG::Graph::Data instance, and all SVG::Graph::Data instances attached to SVG::Graph::Frame subinstances See SVG::Graph::Frame and SVG::Graph::Glyph for details. ONE DATA SET 1. create an SVG::Graph instance 2. create an SVG::Graph::Frame instance by calling SVG::Graph::add_frame(); 3. create an SVG::Graph::Data instance, containing an SVG::Graph::Data::Datum instance for each data point. 4. Attach the SVG::Graph::Data instance to your SVG::Graph::Frame using SVG::Graph::Frame::add_data(); 5. Attach glyphs to the SVG::Graph::Frame instance using SVG::Graph::Frame::add_glyph(); 6. Call SVG::Graph::draw(); MULTIPLE DATA SETS 1. create an SVG::Graph instance 2. create an SVG::Graph::Frame instance by calling SVG::Graph::add_frame(); 3. create an SVG::Graph::Data instance, containing an SVG::Graph::Data::Datum instance for each data point. 4. Attach the SVG::Graph::Data instance to your SVG::Graph::Frame using SVG::Graph::Frame::add_data(); 5. Attach glyphs to the SVG::Graph::Frame instance using SVG::Graph::Frame::add_glyph(); 6. repeat [2-5] for each additional data set to be added. add_frame() can be called on SVG::Graph to add top-level data sets, or SVG::Graph::Frame to add hierarchical data sets. 7. Call SVG::Graph::draw(); FEEDBACK
