How to customize tile layer's legend symbology in ArcGIS Online?

[Anonymous User]

I am using a tile layer of Land Surface Temperature in a Web App in ArcGIS Online. The tile came with its original stretch symbology from blue (cooler) to red (hotter), and both ends of the stretch bar were labelled accordingly.

After publishing and including the tile in a Web App, In both the Layer List and Legend widgets, the following is displayed:

Ideally, I would like to add text labels next to the top and bottom portions of the color bar to indicate what the color scale represents. I have been looking at JavaScript API examples but haven't seen an example of this particular case yet. My questions are:

1. Is this possible to achieve with JS API?

2. If not, is there another way to do this?

Thanks in advance for any ideas!

Hi Byron, quick question. Did you ever resolve this issue? I´d like to do something similar. Take the tile layer legend and try to make it a little more cartographically pleasing so to speak. Many thanks, Dan.

I would like to add text to the min and max of the continuous colour legend for a tile layer. When configuring symbology in ArcGIS Pro the label text I provide for min and max values are displayed in AGOL as "label1 - lable2" in line with the middle of the colour bar.
