Hello, 

I'm trying to get a simple example sparkline working using the specific javascript files that are required.

When it hits the line to create a sparkline for the element, it errors out saying "Cannot read property '$type' of undefined" somewhere in chart_sparkline.js.

If I use the all encompassing scripts (namely, core, lob and dv) it works fine.

The js files I'm including:

infragistics.util.js
infragistics.datasource.js
infragistics.dv.simple.core.js
infragistics.templating.js
infragistics.ui.basechart.js
infragistics.ui.sparkline.js
infragistics.chart_sparkline.js

Any ideas as to what the problem might be?

Thanks in advance for any help.

I added a JS Fiddle demonstrating the issue.  If you comment out the core, lob and dv files and uncomment the recommeded individual js files, you will see the behavior I'm noticing...
