I found some tricks that may be needed someday and I gathered them here:

Table in whatif analysis in Excel is useful. The excel file can be found as Monte Carlo Simulation Valentine (Xlsx file).

 

Chart data label formatting:

To do this you can go to the following link from Microsoft: 

Number-format-codes

For example: 

Insert a chart and add data labels.

Choose format and in the right pane choose

label option> Number > number code

Then you can format your numbers referring to the number format code link provided above. For example:

Red][<=100];[Blue][>100]

 If you want to omit the labels with values less than 12 use the following code:

[<12]"";[>=12]#,##0

The first [] says that if value is less than 12 then put null ("")
