I’m a volunteer developing and managing a web site for a local non-profit. They are starting a money-raising campaign and want me to put a “Donation Thermometer” on their web site. The “thermometer” graphic will have money-level gradations, a red fill will be adjusted incrementally to show the amount of money pledged to-date, etc. Rather than start from scratch on this, I am asking if anyone has done this already and could share with me how they did it. Thanks in Advance!
