[Scatterplot Matrix] of Graph menu and [Multivariate] of Analyze menu are very similar. Combining the two functions into a single one would improve usability.
[Scatterplot Matrix] only offers a scatterplot matrix, while [Multivariate] includes both a correlation matrix and a scatterplot matrix. However, I often waste time looking for a correlation option in [Scatterplot Matrix].
Additionally, there are options that are only available in the [Scatterplot Matrix] and others that are only available in the [Multivariate]. This makes it difficult to know which one to use to create the graph I want.
