HeatMapViewer (v14) BETA

Summary

The HeatMapViewer displays values in a heat map format where by default the largest values are displayed as the reddest (hot), the smallest values are displayed as the bluest (cool), and intermediate values are a lighter color of either blue or red. This is a very convenient way to display three-dimensional data (samples, features, and values). It was created using jHeatmap

Options

There are a number of options controlling the appearance of the heat map that can be set by clicking the Options button: 

• You can choose between radio buttons for Row Relative and Global color schemes. When the relative choice is selected, the heat map converts values to colors using the mean, minimum, and maximum values in each row. When the global choice is selected the heat map converts values to colors using the mean, minimum, and maximum values in the entire dataset.
• You can choose between the radio buttons Use Color Gradient and Use Discrete Colors. The heat map uses linear color gradient to convert values to colors when the Use Color Gradient button is selected, while a discrete color map is used if the Use Discrete Colors button is selected. A color picker is provided for selecting colors. When specifying discrete colors there is no limit on the number of colors that can added.
