Re: [twdev] Re: How to navigate to ids within a tiddler? Or How to add refresh between two steps of a widget

[ajarmund]

Hi!

uplight-dev posted a nice way to catch anchor links 
 in story.js, and ids 
can easily added in heading.js 
,
 
so the problem I guess, as mentioned above, is making unique ids. I was 
wondering if it could be possible to generate ids in heading.js by keeping 
track of nested headings, say we have a tiddler called "tiddlertitle";

! Header1 <- id = tiddlertitle:Header1
!! Header2 <- id = tiddlertitle:Header1:Header2
!!! Header3 <- id = tiddlertitle:Header1:Header2:Header3
!! Header2b <- id = tiddlertitle:Header1:Header2b
!!! Header3 <- id = tiddlertitle:Header1:Header2b:Header3

Can the parser keep track of this, or will it be awfully complicated?

It wouldn't guarantee uniqueness, of course, but it could still be useful, 
especially if transclusions would be treated as "ordinary" tiddler content 
(inheriting the nesting from the transcluding tiddler). Is the structure of 
when/how different parts of the wiki/DOM is parsed documented anywhere?

Best,
Anders

Very nice, Jed! I think easy-to-use data visualisation tools will increase 
the value of tiddlywiki for use in research and academia a lot!

Best,

[twdev] Re: [TW5] Data Visualisation using SVG or Chartist.js

[ajarmund]

Thank you! I updated the macro to have plot width and marker size as 
parameters as well. The hover effect should be customisable through the CSS 
stylesheet, but I guess the plugins by Jed will have more functionality

Best,
Anders

[twdev] Re: [TW5] Data Visualisation using SVG or Chartist.js

[ajarmund]

And now 5.1.20 has been released with mathematical operators! I guess a 
simply SVG approach for plotting the data tiddler "data" (
{"10":0,"40":40,"70":100,"120":90}) can be
\define makePoints()
<$list filter="[[data]indexes[]]" variable="key" >
<$set name="xv" filter="[multiply[$(xs)$]]">
<$set name="xval" filter="[add[10]]">
<$set name="yv" filter="[[data]getindex]">
<$set name="yva" filter="[mulitply[$(ys)$]]">
<$set name="yval" filter="[[110]subtract]">
> cy=<> r="1.5"/>






\end

\define makePlot(xsc ysc)
<$set name="xs" filter="[[100]divide[$xsc$]]">
<$set name="ys" filter="[[100]divide[$ysc$]]">




<>




\end

with call <>

However, what is the best way to transclude such a macro in regard of 
scaling? I tried to make a tiddler calling the macro with type SVG but it 
didn't work, so maybe CSS is the way to go?
