To choose the color scheme on a plate heat map, select the Plate Heat Map, and either:

 

Select the Format tab2D OptionsColor Levels command (Figure 5.111), or

 

Right-click on the Plate Heat Map, select Format from the pop-up menu, and choose Color Levels from the drop down.

The default settings are a Green-Red color scheme, a Style of Mean ± SD, and 3.5 standard deviations on either side of the scale. This means that wells close to the average for the statistic being displayed are colored black, wells that are +3.5 SD from the average are pure red, and wells that are -3.5 SD are pure green.

 

You can select another color scheme using the Selected Color Level drop-down list.

 

Available color schemes are:

 

Blue Gradient

Blue-White-Red

Color Blind

Flame

Green Gradient

Green-Blue

Green-Red

Green-Yellow-Red

Greyscale

Inferno

Inverse Greyscale

Magma

Plasma

Rainbow

Red Gradient

Red-Green

Red-White-Blue

Red-Yellow-Green

Threshold

Viridis

 

The Color Blind option is derived from the color palettes recommended in Getting into Visualization of Large Biological Dat Sets: The 20 Imperatives of Information Design by Martin Kryzwinski et al. More options may be added as requested.

 

Inferno, Magma, Plasma and Viridis color levels are inspired by the "Viridis" palette for R.

 

The Threshold scheme has specific Color Level Properties related to the threshold value (Figure 5.112).

When the Selected Color Level or Style are set to Threshold, you can choose a token (e.g., a statistic based on a control well) to represent the Threshold Value by clicking on the T Button button, or simply type in an arbitrary free text value. Then, set the Below Threshold and Above Threshold colors using the drop-down lists. Wells whose value is below the threshold value will be displayed in the first color, and wells with a value above the threshold value will be displayed in the other color.
