Excel is great at automatically creating a wide variety of charts, lickety split. For some types of data, you may want to create a chart that is not readily apparently. Such is the case with a log/log chart.
The answer to this conundrum is to change which type of chart you use for your data. It seems that Excel will not allow the X axis to use a logarithmic scale for many types of charts. To specify a chart where you can use logarithmic scales on both axes, follow these steps:
Figure 1. The Chart Wizard.
If, for some strange reason, values along the X axis are still not represented in logarithmic scale, you can click on the X axis, choose to format it, and then specify a logarithmic scale.
You should note that this solution will work for many types of charts, but won't work for charts where you need to plot zero or negative values. (Those values don't have a LOG value.)
So why do you need to use a scatter chart for log/log data? Because it is the only type of chart that allows numeric values along the X axis. Other chart types use the X axis for categories of information, not numeric values.
