You want to create an Excel Chart Logarithmic Scale!

You can use the logarithmic scale Excel (Excel log scale) in the Format Axis dialogue box to scale your chart by a base of 10.

What this does is it multiplies the vertical axis units by 10, so it starts at 1, 10, 100, 1000, 10000, 100000, 1000000 etc.  This scales the chart to show a more even spread, like the image below:
