Interpolation

Clicking on the Interp button interpolates the data in the hodograph and Skew-T to 25mb increments. This can add data in sparse regions, and it can thin data in layers of dense observations. Here are two images with the interpolation off and on:

In the hodograph images above, note the purple line is a different length when interpolation is changed.
