[tw5] A very BASIC pie-charting service

Much prettier pie-charts can be created with javascript and CSS.

This is for older folk like me who like BASIC programming.

Enter the following in a tiddler in some TiddlyWiki:
(ignore the triple-backticks; they are just to format the code correctly for TalkTiddlyWiki)

More details in this blog entry.

(By the way, should you actually find this thing useful and you actually like rough-around-the-edges old-school-charm, do save the HTML file and save it where you need it, because my hosted file might not be reliable/stable as a “service”.)


Good stuff!

Oh, just to demonstrate dynamic generation of that URL (scenario: percentage of tiddlers vs percentage of shadows), paste the following into a tiddler in some TiddlyWiki instance:
(if viewing this post in Google Groups, ignore the triple-backtick bookends)

<$let tid_count={{{ [all[tiddlers]count[]] }}}
sh_count={{{ [all[shadows]count[]] }}}
tot_count={{{ [all[shadows]] [all[tiddlers]] +[count[]] }}}
tid_pct = {{{ [<tid_count>divide<tot_count>multiply[100]] }}}
sh_pct = {{{ [<sh_count>divide<tot_count>multiply[100]] }}} >

* Percentage of Tiddlers: <<tid_pct>>
* Percentage of Shadows: <<sh_pct>>

<iframe src={{{ [[https://basicanywheremachine.neocities.org/sample_programs/Pie%20Chart%20Service.prod.run?SCREEN=17&DATA=]] =[<tid_pct>] =[[,]] =[[15]] =[[,]] =[<sh_pct>] =[[,]] =[[42]] =[[,]] +[join[]] }}} style="width:250px;height:250px;"> </iframe>
