When you have a large numerical range of data and you want to plot a graph, you will most probable end up with a skewed looking chart like the one below:
You can use the logarithmic scale (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:
