Re: [Gnuplot-info] Porting from GIF to SVG / HTML5 terminals

[Michael S. <Mic...@bo...>]

Is there any reason the native SVG terminal type does not work for you?  It
creates interactive plots.

gnuplot> help set term svg
 This terminal produces files in the W3C Scalable Vector Graphics format.

 Syntax:
       set terminal svg {size <x>,<y> {|fixed|dynamic}}
                        {mouse} {standalone | jsdir <dirname>}
                        {name <plotname>}
                        {font "<fontname>{,<fontsize>}"} {{no}enhanced}
                        {fontscale <multiplier>}
                        {rounded|butt|square} {solid|dashed} {linewidth
<lw>}
                        {background <rgb_color>}

 where <x> and <y> are the size of the SVG plot to generate,
 `dynamic` allows a svg-viewer to resize plot, whereas the default
 setting, `fixed`, will request an absolute size.

 `linewidth <w>` increases the width of all lines used in the figure
 by a factor of <w>.

 <font> is the name of the default font to use (default Arial) and
 <fontsize> is the font size (in points, default 12). SVG viewing
 programs may substitute other fonts when the file is displayed.

 The enhanced text mode syntax is shared with other gnuplot terminal types.
 See `enhanced` for more details.

 The `mouse` option tells gnuplot to add support for mouse tracking and for
 toggling individual plots on/off by clicking on the corresponding key
entry.
 By default this is done by including a link that points to a script in a
 local directory, usually /usr/local/share/gnuplot/<version>/js.
 You can change this by using the `jsdir` option to specify either a
 different local directory or a general URL. The latter is usually
 appropriate if you are embedding the svg into a web page.
 Alternatively, the `standalone` option embeds the mousing code in the svg
 document itself rather than linking to an external resource.

 When an SVG file will be used in conjunction with external files,
 e.g. if it is referenced by javascript code in a web page or parent
document,
 then a unique name is required to avoid potential conflicting references
 to other SVG plots.  Use the `name` option to ensure uniqueness.
