Extract data from images of graphs (reverse engineer the data)

I have a large set of images. I need software that can read the images. Basically, We just need to take a range of points across the x axis and convert those points to dates based on the x axis labels, then, measure the top of the line and get a dollar amount based on the y axis. Basically, reverse engineer the data out of the images.

The biggest issue is that the range of the x and y axis can vary greatly, so the software will need to read the labels to calculate approximate dates and dollar amounts. I am attaching a sample set of images that show you how the axis can vary.

Please explain how you think you can solve this, what software language, etc. Thank you.

To clarify, I will need various values, interpolated from the data. So we will need to interpolate the dates from the labels and also the different $ amounts from the y axis.
