Plotting
GroIMP embeds the jfreeChart project to enable the visualization of datasets as plots.
Plotting is possible through either the RGG command chart() or through the menu entry “plot” in the dataset explorer.
The plots are displayed in chart panels. These panels are automatically updated when their associated dataset is modified (new data, changed data, …). This enables to have real time feedback.
Area Plot
Displays each column as the area it covers at in each row, with the values on y and the row number on x.
In a datasets with several columns the areas are layered in front of each other from the first column to the last.
Stacked Area Plot
Displays each column as the area it covers at in each row, with the values on y and the row number on x.
In a datasets with several columns the areas are stacked on top of each other, with the first column at the bottom.
Line Plot
Displays the content of each column at each row connected by a line.
In a datasets with several columns, several lines with different colors are used.
Pie Plot
Creates a pie diagram of the first column with one “slice” for each row. The size of the slice depends on the value in the row.
Scatter plot
Displays the content of each column at each row as a point, if the fields of a row hold more than one value (x and y) the points are plotted with the x values on the x axes and the y value on the y axes.
In a datasets with several columns, different colors are used.
XY Plot
Displays the content of each column at each row with a point, if the fields of a row hold more than one value (x and y) the points are plotted with the x values on the x axes and the y value on the y axes.
In a datasets with several columns, several lines with different colors are used.
Histogram
GroIMP can create a histogram over a column of a dataset, to use this the histogram bins have to be defined.
It is possible to have histograms for multiple columns in the same plot in different colors.
Statistics Plot
Displays for each column a bar up to the average of value of the column and add a stistical range.
Waterfall plot
Sry not sure what this does
Time series plot
Similar to a line plot but with time values at the x aches.
