Layer swipe issue

[FanLuo]

Dear all,

I am working on a map with two layers both styling in heat map, hoping to get the swipe to compare one heat map with another. However, no matter which one I chose to be swiped, the two layers will appear/disappear together. 

In contrast, when I changed the style to individual points, the swipe works fine.

Probably create two separate maps and having each contains one heat map could solve it. But it seems really a waste. Any suggestion? I am using the swipe template hosted in ArcGIS Online without any change.

Thanks,

Fan

Hi Fan,

Sorry about the issue. If possible could you share the URL to your web map (assuming the data is not private or proprietary.

Hi Rupert,

Sorry I cannot share the original map.

But I made another story map using public data which performs the same.

Here is the url http://arcg.is/2nX0jLX

Thanks,

Hi Fan

Thanks so much. Hey could you share that story map publicly. I get prompted to sign-in if I try and launch it.

Hi Rupert,

I set it to be accessible to the public. Would you try to open it again?

Sorry for the inconvenience.

Hi Fan -- I believe that for technical reasons the way heatmaps are rendered in a web browser is that all heatmap layers in a map are added to the same client-side layer, so you're not able to swipe them individually as you've discovered. Creating two maps is the way to go here.

Don't worry, it's not a waste -- the Swipe app is designed to work with one or two maps.

Hi Owen, 

Thanks for the reply.

I was wishing that there could be a way to use only one map instead of two. It seems that two maps is the only solution for this task right now.
