Description
TRENDTOOL allows the user to graphically perform univariate analysis of two-way data. Inputs are axis which is the variable scale to plot against [can be omitted] and data the data to plot. Recall that the convention is that rows are samples and columns are variables. If data is omitted, the user is prompted to load a DataSet to analyze.
Right-clicking on the trend data plot allows placement of "markers". Markers return either the height at a point or integrated area between two points. Reference markers can be added to each marker to subtract the height at a point or subtract a two-point baseline from the associated marker. Markers can be saved or loaded using toolbar buttons. A Waterfall plot (linked to axis range shown in data plot) can be created using the waterfall toolbar button.
Results of the analysis are plotted in the trend results plot showing color-coded results of the univariate analysis. It also allows saving analysis results and selection of points to show in the trend data figure.
Applying trend markers to new data: Trend markers can be saved using the save toolbar button in the GUI. These markers can be applied to new data by calling trendtool with the new data and the markers as input. In this case, no GUI is created and the results are simply returned to the caller as a DataSet object.
