Drag bar input form
8 views (last 30 days)
Hi everyone, I havent seen this before and dont know if its possible.
I have an image in 2d array format where the values in this array go from 0-1. I am trying to replace values that are greater than X and less than Y with NaN and surf the image. My code is ready however I am testing out what X and Y should be and it takes a lot of time to change it manually and type the numbers on each iteration. I was wondering if there a way to implement a scale bar similar to the image attached where I can change X and Y by dragging the value on the scale and observe the changes this make to my plot?
