Screenshot: first column (Cell 1) on the X-axis versus all gene names on the Y-Axis.
I'm trying to create a very simple heatmap from a dataset with no transformation.
Our data table was imported successfully and was defined as follow with 600 genes and 30 cell type (numbered from 1 to 30), the values correspond to gene expression values from microarray data :
When creating the heatmap, I followed instruction on spotfire website, click on insert > New visualization > Heat Map
Then, on the Y-axis I select the gene names, from here I faced 2 major issues:
- The heatmap displays only one cell type on the X-Axis, when I click on add, it adds two types of labels, and aggregates with an average value. so 30 cell types turns into 60 columns.
- I just want to use the values of the dataset, without any aggregations, I don't understand why the aggregation shows up at the bottom of the heatmap and why I can't turn it off?? It seems that the option "none" is missing in the drop down menu of the aggregation.
Is there a simple way to just have the gene expression vs cell 1 to 30 on a heatmap in spotfire? (So we should have 600 rows and 30 columns)
