More than one layer

More than one layer

January 25, 2021 at 4:08pm
Hi Ilya - This is a really nice tool. I'm checking in case I've missed something because I was hoping it might be possible to create a map with more than one layer, each layer using its own colours. I can see that I can create different subsets of data using different sheets but I think I can only view one subset at a time. This is an example of the type of thing I'm after - https://teralytics.github.io/flowmap.gl/index.html?path=/story/basic--two-layers

Hi Gordon. It's not possible in Flowmap.Blue at the moment. Yes, you can only see one subset at a time. Could you describe your use case so that I can better understand why that'd be useful?
Hi Ilya. Thanks for getting back to me. The material flows that we're modelling go through two (or more) hops, A to B then B to C. I was wanting to show each of these as a separate layer with separate colours.

Ah, that's interesting. I will think about it. For the moment, maybe you can consider "abusing" the time dimension for that. You wouldn't see them in different colors, but you could at least filter by the "hops".
I can think of adding a dimension "color" similarly to "time" so that each flow can be colored individually
Thanks Ilya. I will have a look at using time in that way but, yes, I can see how adding a color attribute to each flow would work.
