I didn't realize that your datapoints were in different fields like that. That would have to be modified at the chart level then, not in the data itself.</P><P>I would imagine that this is possible in Python. Check out the<A href="https://developers.arcgis.com/python/api-reference/arcgis.apps.dashboard.html#arcgis.apps.dashboard.SerialChart" target="_self"> Dashboard submodule of the API</A>. If you can identify the chart, I think the <STRONG>data</STRONG> property is what you want.</P> Mon, 10 Jan 2022 17:03:16 GMT https://community.esri.com/t5/arcgis-online-questions/how-to-use-arcade-expression-to-dynamically-change/m-p/1132087#M43691 jcarlson 2022-01-10T17:03:16Z https://community.esri.com/t5/arcgis-online-questions/how-to-use-arcade-expression-to-dynamically-change/m-p/1133785#M43760 <P><SPAN>Okay, I'll take a look.
