If it is external file like XL, then maybe do it in XL it self before loading into Qlik Sense?
It will be much easier to do by avoiding the backend scripts.
And to change the name of the field you can use
DATE as Date
Check the below link...
You can change the Label in chart properties which you already know I guess?
But if you have in your script
Effective_Dates as a field name
and in front end in Label you changed it to Start Date.
Then upon selection of that field, on top in current selections, you'll still see the field name as Effective_Dates but not Start Date.
Hence you need to change the names in script only.
At least I did not find any solution to this thing.
Yes,i know that you can change the label in chart properties.
Can you also change a field name from data manager as mentioned below:
1.After u drag n drop an excel file onto app overview,in data manager under Tables ,edit this table .
2. Data manager->Add data->Attach Files->select the file->next->click on file name and change the field name.
Yes Kalpana you can rename the field names either way...
As shown in above image, click the yellow icon after selecting the file and then next to the field on top you can place your cursor to rename the field.
Once you load it the field names will come as
ABC as ABCD
BCD as BCDE.... etc
And also you can do same after making the data connection in Data Load Editor, when you select the file you can place the cursor next to field name and give your new field name...
The end result would be same as above example
