True or False: Excel can create graphs using more than one y-axis.

Excel indeed has the capability to create graphs that utilize more than one y-axis, which is especially useful for comparing different datasets with varying scales on the same chart. This feature allows users to plot data series on separate y-axes, giving a clearer visualization of relationships and trends that might not be as apparent with a single axis.

For instance, if you have one dataset that ranges from 0 to 100 and another that ranges from 1000 to 10000, overlaying them on a single y-axis would make one of the datasets difficult to interpret. By using a secondary y-axis, each dataset can maintain its scale, enhancing the clarity and effectiveness of the graph.

While there are advanced graphing tools and third-party plugins that can expand the functionalities of Excel, the ability to create a chart with multiple y-axes is a built-in feature of the software available in standard versions. This makes the assertion that it can only be done using external tools or that it is restricted to advanced versions incorrect.
