VxCount = !shape!.pointcount fuction in AGOL

GeoPolar

Hi everyone!

it is possible to make an arcade expression from VxCount = !shape!.pointcount Python expression?

This Arcmap/ArcGIS Pro python expression allow to show the total number of vertices of a Feature Class. but what about AGOL Environment?

Thanks!

The example I provided was just to test the function. The return statement at the end of the expression returns OK. You will have to use something like this to make it work:

Hi Miguel Angel Barrientos Martinez ,

You mention that this expression will calculate the vertices of a feature class, but I assume you are mean a feature, since that is what the python expression will do.

In Arcade you can determine the number of vertices, but the expression will probably be different depending the type of geometry you have. On what type of geometry do you want to apply the Arcade expression?

Have a look at the following function:

Function <SPAN class="token function">CountVertices</SPAN><SPAN class="punctuation token">(</SPAN>geom<SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN>

Hi Xander! put this code in custom expression label box in AGOL but all labels created was "OK" butg none with vertex count. BTW this expression is related with a Poliline Feature Class, no Polygon or points. Thanks Xander for your quick response.

ok labels
