Remove selected attributes in WEKA

Question

I am creating a scatterplot of countries with most hotel cancelations and i have accumulated alot of data from various countries and when i visualize the data it does translate well so i need to remove most of the countries from the country attribute but it wont seem to let me do it very easily

I tried using the 'removewithvalue' filter but it is a very time consuming process when there are 178 different countries and it doesn't specifically remove the selected attribute

Answer 1

RemoveWithValues removes the rows in the data of the label indices of the attribute that you've specified. Unless you specify the -H/modifyHeader option/property to also remove these labels from the attribute definition, the predefined labels will still be present as valid labels, but with 0 occurences.
