#10 – Take away Map Layer
A simple option to create a clear map on your visualization is eradicating the map layers. Choose Map on the toolbar and « Map Layer » after which uncheck the whole lot within the map layers window. This can depart solely the define of the map knowledge.
#9 – Change Map Border Colours
When utilizing a map, you possibly can change the border colours underneath Shade. Choose Shade and select the border colour you need.
#8 – Create US Map Define
Combining Tip #10 and #9 and eradicating the fill colour we are able to create a map define. First take away the map layer (Tip #10) after which set the map fill colour to match the background colour. Then colour the borders to the specified colour (Tip #9). We now have simply an overview of the map.
#7 – Create a Minimalistic Map
I first posted about this here. By eradicating the bottom layer (much like Tip #10), we are able to change the Pane colour to vary the water colour on the map to any colour. As soon as the bottom layer is unchecked, merely right-click on the map and choose « Format », then choose « Shading » and alter the « Pane » colour to the specified colour.
#6 – International locations of the World Define
Just like Tip #8, we are able to create and description of the nations. On this instance I additionally mixed Tip #7 to vary the pane colour to match. This creates a purple define of the nations on a very black background.
#5 – Add Map Gridlines
Proper-click on the map and choose « Format » then choose gridlines for the Rows and Columns and alter to the specified colour and transparency.
#4 – Information Layer as Map Background
Tableau has built-in knowledge layers for the US. By including customized colours within the desire file we are able to use these as background colours. I’ve created a « black to black » colour within the desire file. This permits me to make use of inhabitants on the stage of state, utilizing « black to black » as the colour scheme to paint the whole lot black. Then making use of Tip #10 and #7 to create a minimalistic map with dots.
#3 – Twin Axis Map Various
First we construct our map with gross sales by metropolis. Then duplicate the Longitude on the columns. On the primary Longitude capsule, take away the whole lot besides state. Then change fill colour and boder colours to black. On the second Longitude capsule change the colour to the specified colour and transparency. Take away the map layers (Tip #10) after which change the Pane background colour (Tip #7).
#2 – Excessive Distinction Maps
Tableau has three base map choices; regular, gentle and darkish. These maps are properly accomplished, however typically occasions do not have sufficient distinction. That is particularly the case when projecting on screens utilizing numerous projectors. One possibility is to make use of Mapbox maps and there’s a excessive distinction possibility that is without doubt one of the defaults in Mapbox. You may also create your individual customized maps in Mapbox. Nonetheless, there are a number of alternate options for doing this in Tableau with out the necessity for Mapbox. I posted one different methodology here, however this solely works the place there’s a knowledge layer out there. Right here is one other different that can be utilized for any map and can be utilized to create excessive distinction for each gentle and darkish maps.
The secret is to take away the bottom layer and altering the background colour of the Pane, as we did in Tip #7. The distinction on this case is that we maintain the Streets and Highways checked underneath the map layers (and Land Cowl if desired). For a lightweight map with darkish streets then select the « Darkish » map type and set the Pane to white or one other gentle background colour.
For a darkish map with very gentle streets then select the « Mild » or « Regular » map type and set the Pane colour to a darkish or black background.
#1 – Create a New Map Fashion within the TMS
You possibly can add a brand new map type to your TMS to make use of the type time and again and make it even simpler to make use of.
IMPORTANT: Change the inline= »true » within the opening traces of your TMS file if you’d like your new customized map type to save lots of in your Tableau file or on Tableau Public. <mapsource inline= »true » model= »10.0″>
Under is a pattern Map Fashion so that you can copy and paste into your TMS file. Then open Tableau, create a map and this new map type « Darkish Distinction » ought to seem in your record. Uncheck Base and set the opposite map layers choices as desired.
This map units a darkish background utilizing <map-layer-style identify= »background_color » request-string= »#000000″/> and combines that with the opposite parts of the « Regular » map utilizing « from=tableau4_2_water » and « from=tableau4_2_landcover ». When the « Base » map layer is unchecked the ensuing map will look much like the map beneath.
