Description uwestoehr 2018-11-06 13:18:25 UTC 
In terms of working speed I see room of improvement. An example:

- start LabPlot
- create a new spreadsheet

result: the number format is by default:
x,yyyyyy+ezz
This is in my opinion not the most used format and should just be a float with 4 digits by default: x,yyyy

However the function to fill a column with row numbers is commonly used. In this case the number formal of the row should automatically be set to float where the empty digits are not shown or to integer because when I fill the column with integer row numbers, another number format doesn't make sense.
In case I apply a formula on the row numbers the number format should automatically be changed to float with 4 shown digits.

This would speed up my work flow a lot.

There are many other workflows where the scientific representation is more desired than the decimal or where 4 digits in the decimal format are not sufficient. We'll think how to make this setting configurable.

To convert the column type to Integer when filling with row number makes sense. The same when applying a function where we can convert to float. I'll implement this.
