I have three variables X, Y and Z with 10, 60 and 3 levels.

For example, Variable X is 10 regions Variable Y is 60 genes Variable Z is each gene's expression in 3 times.

How can I plot them? I wanted to plot a heatmap but the plot looks strange as the levels of my variables are so different. What plot is best to describe these data? I thought of clustering my genes maybe.

How to plot the data depends on what you want to get out of it and is something only you can know. Some options are:

  • Plot each of the 60 genes separately, with grouped bar or symbol charts (grouped by region or time with the other color-coded).
  • Plot density plots that are grouped by either region or time.

You won't actually plot X or Y, only the expression values, the rest should be used for either summarization or grouping/coloring/etc.

Thank you a lot. I grouped my data based on region and plotted 10 heatmaps in one plot.
