How to leave map representation in blank until filter are not selected

[S10]

I want to realize an interactive graph where once select Filter Continents and Major Deaths causes (that you might see it has varibale number of subfilter) it starts to color map according to spread of deaths in population.The problem is that with no selection (Blank filters) there is this default color on the map. I know that I to create measure and I have tried to define 5 measur for each level of disease based on this code

INT(CALCULATE(ISFILTERED(Mortality[Code]),ALLSELECTED()))

I entered it in map filter but unfortunately it seem to work. Countries become blank as they are not selected but color does not change over year. What can I do?
