If I read this correctly, you want to generate a blank graph with the right scales.
Define a line in Excel from the bottom left to top right of the area that you want a graph of, ideally in columns with 4 points or more.
Use the chart wizard to create a graph with this line in it. Adjust the axes to give the grid spacing and labelling intervals you want by double clicking on them and following the options. I'd personally also right click in the graph to change the background colour to white.
Then right click on the data on the graph. Select "format data series", and for both line and data select "none" under the "patterns" tab.
Click OK.
You can then delete the key on the left hand side, add using drawing tool any labels or lines that you want, then cut and paste into word.
