Oliver Schmidt (Member) asked a question.
I am using Tableau 2023.3. In maps, I notice that the green color from the underlying landscape interferes with the colors the user assigns. For eg, in the map below Postcodes have been divided into two groups - A and B. Group A is assigned color Blue and Group B is assigned Orange. In the map background, there are green areas. Wherever this green color overlaps with assigned color, it mixes with it and produces a new color, giving a wrong impression that there are additional groups. I have marked them below
I am using Opacity of 30%, and can't exceed beyond much, as I want the end user to see the underlying map (location of cities etc).
How to turn off these green areas from the background, so that Street Map looks just like the one in the lower part of the picture above? I tried playing around with "Map->Background Layers->Background Map Layers", but didn't help.
Any suggestions? Attached is the dataset and .twbx file.
Thanks a lot.

I created a map using a .shp file and have no background layers selected, however, when I hover over a district, the streets show up. Is there a way to remove that, or to change the colors of the street lines?

I've attached my package workbook here.
My dataset has Regions for each set of Lat/Long. So after creating my map I went (right click) Region > Geographic Role > Create From... > State
Then I dragged this Region hierarchy onto the detail marks card to get all the Regions outlined in the map. My intention is to use this Map as a Region selector on the dashboard to filter the bar chart. So, for example, if the Midwest region is selected on the map then the bar chart will only show Midwest numbers (and vice versa - if the user selects a year bar first then the map will filter to only that year's data - this seems to be working). However, when the Region is clicked on it's only passing one set of Lat/Long for the region. I notice even when I hover over a region in the map the tooltip only shows one set of Lat/Long as well.
When I look at the Action Filter I notice it's filtering on fields [Region] [Latitude] [Longitude] so it explains why it's happening, but I don't know how to get all Lat/Longs in each region to pass. I've even tried creating copies of Lat/Long and turning them into dimensions and dragging them into the Region hierarchy but it doesn't work. And I even tried creating a geographic role on Lat/Long from Region but that doesn't work.
Is there any way to achieve this? I've been up all night trying to figure it out, would be a huge help. Thank you in advance!

Hello everyone!
This is a rather Beginner-level tableau user trying to map the transport flows of a client for my internship task.
I have the departure and destination longitude and latitudes for each transport separately, along with weight and volume shipped. In an ideal state, I'd like to map all transports so I have a clear visualization where all transports come from and where they go to. This will help me on my journey to find improvements in terms of CO2 exhaust.
I was able to map the departure cities and dragged weight to size. This way, I can see where the largest sum of weight departs. Now, however, I am struggling to add the destinations. If I try to add the destinations, the map will be split in two (in other words, another map will be created with the destinations only, instead of putting them together).
Does anybody know how I can solve this issue?
Thanks in advance and I wish you a wonderful weekend!
Stay safe.

I created a parameter - [Choose a Metric], with options for Revenue, Profit, Units Sold and Cost of Goods and created a calculated field to switch between the selected metrics based on the parameter using CASE. (CASE [Choose a Metric] WHEN 'Revenue' THEN [Revenue] WHEN 'Profit' THEN [Profit] WHEN 'Units Sold' THEN [Units Sold] WHEN 'Cost of Goods' THEN [Cost of Goods Sold] ENDI tried to add a quarterly date filter to my view, but when I do, I get the error mentioned above.
