Warrants are always going to be priced at PPS - $4.00 + premium.
The premium will generally be between $0.50 and $1.50 depending on (a) volatility, (b) time remaining before expiration and (c) how far the warrants are in or out of the money (above or below $4.00).
There really is no need for a chart.
If the share price is $14, the warrants will likely be between $10.50 and $11.50 (depending on the premium).
If the share price is $20, the warrants will be between $16.50 and $17.50.
