I have a saved script for a ternary plot. The contour formula for the ternary plot contains a reference to a fourth column (besides the three plotting columns), so the default ternary plot includes a slider for controlling the value of this fourth input. I would like to change the lower and upper limits for the slider. I understand I need to send the Reset Slider() message to the slider, but I can't figure out how to send this message to the appropriate entity in the display. Please advise.
