As is typical with parallel coordinates, Sliver plots values linearly along each axis between its minimum maximum value. Sometimes data is better visualized when plotted non-linearly, say on a logarithmic scale. To do this, you can create new data columns that are functions of the original data columns. You might do this in Excel, or you can use the DataTools-->Add Column of Calculated Values menu option. Since PC plots don't typically have tick marks, there is no need to adjust the spacing of these along the axes.
