For some reason, while the rest of my exhibit works, Timeline fails. I just
want a timeline of when people entered and
exited their main company (in this example, Xerox PARC) and I encode this as
dates.
Seem to have just ran into an error message that I don't understand. I'm
copying the Presidents.html file and JSON pretty closely in my work, just
modifying them to fit an exhibit about inventors of computer technology.
Here's the message:
I get this error message: "Caught Exception: Error adding section
{select Worked At view} to history
Details: TypeError:this._dom.timeline has no properties
Strange. It *appears* to have properties to me. My HTML is here:
---
<div ex:role="exhibit-view"
ex:viewClass="Exhibit.TimelineView"
ex:label="Timeline"
ex:proxy=".index"
ex:start=".start"
ex:leave=".leave"
ex:marker=".institution"
ex:bubbleWidth="320"
ex:bubbleHeight="200"
></div>
-----
HTML: http://vis.duke.edu/Research/interface/inventors.html
JSON: http://vis.duke.edu/Research/interface/inventors.js
JSON: http://vis.duke.edu/Research/interface/schema.js
Any ideas what's going on? Since the inventors don't have a strict linear order
like Presidents, I use proxy "index" instead of "president"...
Also, secondary question - for this historical work, we usually don't have
exact dates? Is it possible to use timeline with
just years, and in that case how does it impact schema.js and do I just put
integers in as years?
