I would like to create a bar-chart (or a histogram?) with vertical bars and a numerical x-axis , but I do not know how/where to start. I have MS-Excel and Origin-plot available with me. My intended chart would look like this:
You can more or less get what you want by adding and styling error bars appropriately to a scatter plot. The error bar is a simple way to force Excel to draw a line under/over the point.
Chart with data and error bars
Couple steps
You could take these steps and codify them with some VBA to prevent the tedious nature of doing this multiple times. Setting error bars is one of the worst activities to have to do continually.
I believe you should also be able to get your desired colors by adding multiple series. Possibly all the more reason to do this with VBA.
