Trace Tags for interpolated wave values

Currently, I can only add a tag for a trace on integer point numbers.

There are many instances where I would love for the tag to be placed at a value along a trace between two points.

It would be great if I can place a tag along a trace at any specified x-value, allowing me to put a tag on the linearly interpolated value that matches my specified x-coordinate for a trace.

An interesting idea, but so far Igor doesn't do that. You could accomplish something similiar with drawing objects that use axis coordinates.

As a workaround, create a one point wave, set the scale so that the x value is your position of interest, then use interpolate2 (or the interpolate dialog) to set the y value (destination x-coordinates from destination wave). Add that wave to your plot and attach the tag to the 1 point wave.
