Figure 1: An example histogram of immunohistochemistry (IHC) score frequencies
To select a marker, click on its name in the tabs at the top. With a marker selected, you will see the histogram on the left, and descriptive statistics on the right.
The histogram shows how the score categories for the marker are distributed. On the x-axis is the score, and on the y-axis is the count, or frequency, of that score category. A higher bar indicates the score category is more frequent for that marker, whereas a smaller bar indicates the score category is less frequent.
The buttons on the right-hand side are:
- Open in new window - Open the current plot in a new window. Useful for comparing multiple plots side-by-side.
- Download as SVG image - Download the current image in scalable vector graphic (SVG) format. SVG images can be rescaled to any size without loss of quality, ideal for posters and publications.
The statistics on the right are given for each score category as follows:
- Score frequency - The number of samples within a score category.
- Score frequency (%) - The percentage of samples within a score category.
