This should be a color gradient, red-to-white-to-blue, with tick marks at +1/0/-1, in a small vertically-oriented box on the right side of the plot.\r\n\r\nIn a transposed heatmap (#35), the box should be at the bottom oriented horizontally, with red on the left.\r\n\r\nConsider recreating the same in Reportlab for the 'diagram' plot."}}
