How to remove trailing zeros from QGIS Graduated Style Class labels?

I'm sure I've seen a solution to this before but now I can't find it.

When using the graduated fill style in QGIS I get lots of trailing zeros in the labels. This makes my legends look messy in the print composer.

Is there a way to automatically remove these?

Answer

Here's the simplest method I've found so far:

1. Open layer properties


2. Save style as a QGIS Layer Style File


3. Open the resulting .qml style file in your favourite text editor


4. Use find and replace to identify trailing zeros and replace with a zero length string


5. Apply the altered layer style in QGIS

Note: Be careful when doing the find and replace as the lower & upper values may have a different number of trailing zeros to the label value. If you're not careful you can accidentally increase the values by factors of ten!
