The out of the box functionality in Qlik classifies data into equal intervals and does not allow me to choose the number of classes used to classify the data. For example, when mapping on a measure Qlik defaults to using 7 classes. How can I change it to 5 classes?
Qlik also classifies data using the equal interval method as default. Is there a way to change the data classification method and classify data into quantiles? Can this be achieved in the expression editor using an expression?
However, when I use the colour by expression method to colour my map, it does not display a legend. Is there a way to display a legend showing the ranges for each category/quantile?
Also, I realize that the fractile expression plays a key role in calculating the quantiles. If I wanted to classify the data using a different method, such as equal intervals or natural breaks, what are the appropriate expressions used for these classification methods?
