“problem” in Chart

Hi!
I have managed tu use this plugin in a new online shop, with woocommerce system, to sell a product based on its length. This plugin is fine to set a minimun quantity, and the base unit. Then you can choose in the product’s page the desired quantity, BUT: if, for instance, i choose 32 centimeters of something, then i see 32 items in the chart. Is it possible to change this behaviour, showing for example another value? (different SKUs, etc…). Thank you all!
