Making A Simple Chart

Im trying to create a bar chart that contains required hours per week with a line of hours worked going across the bars, im struggling to make this work and have basically no experience of making any sort of charts or graphs.

I need to create this using vba but to begin with I cant even make the chart manually! Where its all going wrong is the column line for required hours is so thin it looks rubbish. Its a bar chart then I formatted the series of total hours to be a line chart.
