create a chart using google charts on my webpage

I have a page in my wordpress website where I calculate the principal and interest components of a home loan for different amounts, terms and interest rates. The output needs to be displayed in a tabular format( already done... if you could improve it , well and good) and this generated data needs to be displayed in the form of a combined bargraph and line chart where we have the years on the x axis and the varying principal and emi componens on the y axis (the monthly emi would be the same so all the bars would have the same lengths, they will have differnet divisions for the principal and interest components. Refer to [login to view URL] to get an idea of what I want. I will also be needing a pie chart as given in the above mentioned url. Ideally I would like this made in google charts it being free and open source but I am open to ideas. This is a simple project , you just need to set up the chart using Google charts API and shouldn't take more than a day.
