Display intensity versus ratio scatter plot for microarray signals
mairplot(X, Y, 'PropertyName', PropertyValue...) mairplot(..., 'FactorLines', FactorLinesValue) mairplot(..., 'Title', TitleValue) mairplot(..., 'Labels', LabelsValue) mairmage(..., 'HandleGraphicsPropertyName' PropertyValue) [Intensity, Ratio] = mairplot(...) [Intensity, Ratio, H] = mairplot(...)
| X, Y | Gene expression data. |
| FactorLines | Property to specify a factor of change. |
| Title | Property to specify a title for the plot. |
| Labels | Property to specify labels for the plot. |
| HandleGraphics | Property to pass optional property name/value pairs from Handle Graphics. |
mairplot(X, Y, 'PropertyName', PropertyValue...) creates an intensity versus ratio scatter plot of X versus Y.
mairplot(..., 'FactorLines', FactorLinesValue) adds lines showing a factor of N change.
mairplot(..., 'Title', TitleValue) allows you to specify a title for the plot.
mairplot(..., 'Labels', LabelsValue) allows you to specify a cell array of labels for the data. If labels are defined, then clicking a point on the plot shows the label corresponding to that point.
maimage(..., 'HandleGraphicsPropertyName' PropertyValue) allows you to pass optional Handle Graphics property name/property value pairs to the function.
[Intensity, Ratio] = mairplot(...) returns the intensity and ratio values.
[Intensity, Ratio, H] = mairplot(...) returns the handle of the plot.
