// increment the prices pointer, we will move to the left, and the prices
// should be getting older.  We will stop when we run out of space on the

// out of prices, then the left part of the chart will be solid black.

// Note, in the delphi code the order of the prices is different.  This
// seemed like it would be easier for the caller.
