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 http://www.tools4all.net/EMI-Calculator#.UWphsj7zo6L 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.
