Repeat?

[glutamate]

How about being able to repeat plot lines? Maybe I can already use ng-repeat?

right now to plot probability distributions over lines, i have to generate this

<plot>
<lines x="[[plotb4_1[0]#x]]" y="[[plotb4_1[0]#y]]"></lines>
<lines x="[[plotb4_1[1]#x]]" y="[[plotb4_1[1]#y]]"></lines>
<lines x="[[plotb4_1[2]#x]]" y="[[plotb4_1[2]#y]]"></lines>
<lines x="[[plotb4_1[3]#x]]" y="[[plotb4_1[3]#y]]"></lines>
<lines x="[[plotb4_1[4]#x]]" y="[[plotb4_1[4]#y]]"></lines>
<lines x="[[plotb4_1[5]#x]]" y="[[plotb4_1[5]#y]]"></lines>
<lines x="[[plotb4_1[6]#x]]" y="[[plotb4_1[6]#y]]"></lines>
<lines x="[[plotb4_1[7]#x]]" y="[[plotb4_1[7]#y]]"></lines>
<lines x="[[plotb4_1[8]#x]]" y="[[plotb4_1[8]#y]]"></lines>
<lines x="[[plotb4_1[9]#x]]" y="[[plotb4_1[9]#y]]"></lines>
</plot>

Any way to do this with one line?

I'll try ng-repeat.

I think ng-repeat should work:

<plot>
  <lines ng-repeat="i in is" x="[[plotb4_1[{{i}}]#x]]" y="[[plotb4_1[{{i}}]#y]]"></lines>
</plot>

Kind of ugly, but Angular expressions inside Radian expressions do work. My only worry might be the scope games that ng-repeat plays, but I think it should work. I'll check tomorrow.

Thanks, it works. However, I didn't think about how to generate the range. I have done this for now by bringing underscope.js into $scope

[ian-ross]

You don't need the range. I thought of a better way to do it:

<plot>
  <lines ng-repeat="d in plotb4_1" x="[[{{d}}#x]]" y="[[{{d}}#y]]"></lines>
</plot>

ng-repeat will loop across any array.

Yes much better thanks On 24 Mar 2013 08:10, "Ian Ross" notifications@github.com wrote:

Doesn't seem to work though:

Oops. Just drop the curly brackets:

<plot>
  <points ng-repeat="p in plotdw" x="[[p#x]]" y="[[p#y]]"></points>
</plot>

Danke! Ca marche!

[ian-ross]

Yeah. Although you can embed Angular expressions within Radian expressions, it actually seems to work better (and be more efficient) just to rely on the way that Radian handles free variables in expressions by evaluating them in the enclosing Angular scope. Combined with the "free variable watchers" to catch updates to these things, it's pretty reliable. I'm not 100% sure why this case didn't work with the Angular expression wrapped inside the Radian expression, but I guess it might be something to do with the way that ng-repeat works.

Any reference within a Radian expression to a free variable v should be equivalent to the Angular expression {{v}} (references to free variables are translated into calls to scope.$eval), so it mostly ought to be better to just use the undecorated variable and rely on Radian.
