I guess I didn't explain it very well.
I'm using a HLinearGauge to allow users to select a range of values, in this case currency. They are selecting what cost they would like to purchase an insurance policy. My linear gauge works fine, I can use the pointer to slide back and forth and select a currency value. No problem. However, the values that show up are not values that the policy supports. For example, I can select a value of 24,289 (see screenshot). I don’t want that I would like either 24,000 or 24,500. So I would like to force the linear gauge to only select increments of $500. So, …, $15,000, $15,500, $16,000, $16,500,…
I've attached a screenshot of what my linear gauge currrently looks like.
