Symbolise by Age with a Live Feature Class

Anonymous User

Hi all,

Is it possible to symbolise by age in ArcGIS Online Map Viewer on a Live Feature Class.

I can symbolise by age, however it requries that you set a date for the symbology to apply to, unfortunately you cannot select latest date for example.

If not possible I'll submit as an idea.

Cheers,

Cam

Hi Cameron McArtney‌,

This is an example arcade expression which classifies features based on current date.

<SPAN class="keyword token">if</SPAN> <SPAN class="punctuation token">(</SPAN>DateDiff<SPAN class="punctuation token">(</SPAN>Now<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">,</SPAN> Date<SPAN class="punctuation token">(</SPAN>$feature<SPAN class="punctuation token">.</SPAN>Date_Stamp<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'days'</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token"><=</SPAN> <SPAN class="number token">1</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN>

Cameron McArtney‌, never done it before and just a suggestion, can you use arcade expression to get the age then apply the symbology? Similar to
