Interacting with the plots
Within the frame
Dataviewer, the right part of the interface holds a panel with several tabs to interact with the plots:
- The tab
Settingsprovides options specific to each plot, such as hiding or displaying elements of the plot, modifying some elements, or changing axes scales and limits.
- The tab
Stratifycan be used to select one or several covariates for splitting, filtering or coloring the points of the plot.
Stratification: split, color, filter
Stratify tab allows to create and use covariates for stratification purposes. It is possible to select one or several covariates for splitting, filtering or coloring the data set or the diagnosis plots as exposed on the following video.
The following figure shows a plot of the concentration from the warfarin dataset, stratified by coloring individuals according to the continuous covariate wt: the observed data is divided into three groups, which were set to equal size with the button
rescale. It is also possible to set groups of equal width, or to personalize the bins.
Moreover, clicking on a group on the right side panel highlights only the individuals belonging to this group, as can be seen below:
Values of categorical covariates can also be assigned to new groups, which can then be used for stratification.
The layout can be modified with buttons on top of each plot to select the number of plots (green highlight below), to arrange the layout (purple highlight below) and to remove the settings frame (pink highlight).
The layout button (second button) can be used to select predefined layouts for the subplots, for instance all subplots in one row or all subplots in one column.
