When indexes in a vfp table are unsorted, the plugin seems to read them as if they were sorted, instead of reading the actual indexes. This leads to inconsistency between filter values and the corresponding plotted curves.
An example of unsorted indexes in this context could be (reversed order)
The effect is illustrated in the picture below where the reversed order of indexes leads to low OGR (=high GOR) and the high OGR (=low GOR) being "flipped"
