I have three columns of data. The first column are dates, the second has data that varies from 0.001 to 100, and the third column has data that varies from 6,000 to 14,000.
My question is how do I plot the third column in the same graph? I need to see how the data varies for the third column in relation to the 2nd column.
I would like to see the dates as the x-axis - along the bottom of the graph, the second column along the left side of the graph, and the third column alongside the right side of the graph. If this is not possible then all I need to see the dates (x-axis), and the 2nd column along the right side of the chart.
Here is what I am getting now, the 3rd column is the blue line sloping up from the bottom left.
