Examples with MatrixDisplay ubic.basecode.graphics.MatrixDisplay used on opensource projects

Example 1 with MatrixDisplay

use of ubic.basecode.graphics.MatrixDisplay in project Gemma by PavlidisLab.

the class ExperimentalDesignVisualizationServiceImpl method writeImage.

/**
 * Test method.
 */
private void writeImage(ColorMatrix<String, String> matrix, File outputFile) throws IOException {
    MatrixDisplay<String, String> writer = new MatrixDisplay<>(matrix);
    writer.setCellSize(new Dimension(18, 18));
    writer.saveImage(matrix, outputFile.getAbsolutePath(), true, false, true);
}

Example 2 with MatrixDisplay

use of ubic.basecode.graphics.MatrixDisplay in project Gemma by PavlidisLab.

the class ExpressionExperimentQCController method visualizeCorrMat.

/**
 * @param id         of experiment
 * @param size       Multiplier on the cell size. 1 or null for standard small size.
 * @param text       if true, output a tabbed file instead of a png
 * @param showLabels if the row and column labels of the matrix should be shown.
 * @param os         response output stream
