Data plotted on XY scatter graph based on selection from dropdown list

Hope someone can help with this.

I have 7 pieces of equipment (A to G). I would like to be able to plot various factors on a single XY scatter graph.

For equipment A to C the factors would be sensitivity vs dose.

For equipment D & E the factors would be pixels vs Log (dose).

For equipment F & G the factors would be pixels vs dose.

I would like the user to be able to select the piece of equipment from a dropdown list and the factors to plot be known automatically on the single graph, from then which data can be extracted and analysed.

Is this possible?

Thank you in advance
