Unlike other meters, custom meters use images as the visual element. Because Ultimeter cannot process what that image may look like to a human, it cannot make use of our standard milestones feature. Milestones use percentages to determine where to place a label. Custom meters do not have a defined percentage range, as you could upload an image that actually only uses the top 10% as the meter itself.
We recommend you create your milestones as part of the image itself. Below is an example of a fantastic custom meter that uses it’s own milestones.
