Heatmap Renderer

Creates a heatmap-graph image.

options

• width (int) - Number of pixels the resulting image is wide. Default is 700
• height (int) - Number of pixels the resulting image is high. This will be adjusted to at least rows * min_cell_height + legend and tree heights. Default is 600.
• tree_height (int) - Number of pixels the dendogram tree for the columns is high. Default is 50.
• tree_width (int) - Number of pixels the dendogram tree for the rows is wide. Default is 50.
• legend_height (int) - Number of pixels for the column names. Default is 250.
• legend_width (int) - Number of pixels for the row names. Default is 250.
• row_text_size (int) - Number of pixels of the row text font size. Default is 15.
• col_text_size (int) - Number of pixels of the column text font size. Default is 15.
• min_cell_height (int) - Minimum number of pixels a row is high. This may cause the defined height of the resulting image to be overwritten. Default is 19.
• selectedRows (array of boolean) - Returns an array that has a value of true for all row indices that are currently selected.
• showScale (boolean) - Indicates whether a scale should be drawn. Default is true.
• colorScale (string) - Can be either red2green or yellow2blue and determines the color range. Default is red2green.
• data (object) -
  • columns (array of string) - names of the columns
  • rows (array of string) - names of the rows
  • colindex (array of int) - 1 based indices of the original column order. This converts the original order (columns) into the one ordered by distance.
  • rowindex (array of int) - 1 based indices of the original row order. This converts the original order (rows) into the one ordered by distance.
  • coldend (array of array of float) - distance matrix for the columns
  • rowdend (array of array of float) - distance matrix for the rows
  • data (array of array of float) - normalized value matrix
