Hi,

Ive made a GUI with a slider bar. I really dont understand one of my slider bars because it misses random numbers out. If i move the slider up and down, its the same numbers that are missed out but there is no logic to it.

The step values are, x resolution is 0.001 and the y resolution is 0.5.
Max value is 150 and the min value is 0.

When i collect the value this is the line that i use.

GridSize = round(get(handles.grid_slider2,'value'))

Because i am using it for a grid, the numbers need to be whole and this is the reason why i have rounded the number.

Any help will be great thanks!

Rob

Problem solved. The resolution was wrong. To calculate the step value.
1/(max value - min value) = step resolution.
