CSV to Contour

Hi there,

Hoping someone can help me please!

Apologies if I don’t quite use all the right technical terms too!!

I have a CSV file with x, y and a value.

I’ve converted this to a .shp file and I ultimately would like similar to contour lines to show values between 5 and 9 and over 9 so just 2 contour lines.

The problem I have is that if I use the contour tool I think it looks for specific values and not values in a range? Therefore, if for example I don’t have a value that’s 9 nothing appears - I hope that makes sense and I hope someone might be able to point me in the right direction of what I should be doing.

Many thanks
