Tableau: Background color based axis value - tableau-api

I want to color background based on axis value in tableau as in below image:

Once you have your Viz setup...
click on the Analytics Tab (top right next to the Data Tab)
drag Distribution Band onto the Viz and drop it on the Table element
set the values for the 2 band breaks (looks like ~33% and 68%)
click the 'Fill Above' and 'Fill Below' checkboxes in the middle Formatting section
click the 'Fill' dropdown and select the color palette you want
You can also create custom color palettes if the defaults do not meet your needs.

How to Remove on Vertical Gridlines in Tableau Desktop App

I would like to only remove the vertical gridlines from a Tableau chart. I am aware that I can go to Format > Lines > Gridlines > Set to NONE. But this removes both vertical and horizontal gridlines. I am trying to only remove the vertical gridlines. (See the screenshot. I have made the gridlines little darker to demonstrate my question).
I looked around, but could not find a solution. Please help.
On the Column Divider from the Format Boarders menu, move the Level slider to the left.
Result:
At the top of the format pane in the left side bar, don't select the Borders icon (which looks like a little grid) Instead, select the Lines icon just to the right (which looks like a set of different width lines)
The Borders settings control the display of borders between cells and panes, i.e. the parts of the view created when putting discrete (blue) fields on the Rows or Columns shelves.
The Lines settings control the display of the axis, grid and other lines, i.e. the parts of the view created when putting continuous (green) fields on the Rows or Columns shelves.
Once you are working with the Lines format settings, you can scope your changes to either just the vertical grid lines, just the horizontal grid lines, or both by selecting Sheet, Rows or Columns from the tab just under the icons discussed above.
Experiment to get the hang of it. Whenever you change a setting from the default value, the title goes bold. You can right click on bold titles to clear the change, or you can clear all the changes to a section by hitting clear at the bottom of the format pane. So its easy to undo a change you don't like, allowing you to experiment with confidence to learn how the settings work.

How can I put different colors for the different elements of a single dimension

How can I set different colors for the different elements of a single dimension with Tableau Desktop?
I want the colors in fields of dimension and not like the picture.
Thank you
You can drag that same dimension on the Color mark in the Marks area, which by default is displayed below filters, right to the Data area.
To change the colors that Tableau assigns by default you can click on the Color mark and use "Select Colors": it will open a window where you can select the color you want for each value of the dimension you're using.
Edit
Unfortunately you cannot color the background of a dimension axis. You can achieve the same result with a trick though:
Drag the dimension to rows
Double-click in columns and write MIN(1)
From the marks dropdown, make sure Bar is selected
Drag the dimension to the Color mark
Drag the dimension to the Label mark
From the Label mark, set the horizontal alignment to either left or center
From the Label mark, mark the flag to allow labels to overlap other marks
From the Size mark, crank the size all the way up
Right-click on the dimension from the rows area and unselect Show Header
Right click on the MIN(1) axis below the graph, click Edit Axis, select Fixed among the Range options and fix start and end to 0 and 1 respectively
Right click on the MIN(1) from the columns area and unselect Show Header
Of course adjustments can be made to better suit your needs, but this should give you an idea of the whole process.

How to change border thickness on a Polygon in Tableau Desktop?

I have a simple polygon in Tableau Desktop. I know you can easily change the color of the border but there seems no way to change the thickness.
My shape looks like:
Then when you click on 'Color'. You can click on the Border drop down and select the color but not the thickness. Is there another way to do this?
Use a dual axis
Put the field you have on the column shelf on the column shelf twice to get 2 side by side graphs. On the marks card, select the second mark, and change the mark type to line. Adjust color and size to suit.
On the column shelf, right click on the second mark and choose dual axis and synchronize axes (by editing the second axis and checking the synch axes box). If you want to change the order that marks are drawn, you can switch the order of the fields on the column shelf. You might want to hide a header

tableau adjust placement of gantt bars

In Tableau, I have a dual-axis bar chart of some data with their margins of error. I am using Gantt bars for the error data, and I want to overlay the error bars on top of the original data. My problem is that I can't figure out how to adjust the placement of the Gantt bars so that they are centered over the top of the original bars, with the error value displayed both above and below the bar.
I am pretty sure I need to create a Calculated Field but am new to Tableau and coding and don't really know how to go about this.
You can do this without the use of Calculated Fields as follows:
Create a Bar Chart with the original data
Duplicate the Bar Chart by Ctrl-Clicking the measure pill in the Rows shelf
You should get 2 charts one above the other now, select one of the charts from the Marks dialog, and change it to Gnatt Bar
Drag error to the Size button of the Gnatt Bar and also to the Color button
Now click the one of the pills in the row shelf and select Dual Axis
Right click the second Axis and select synchronize Axis
