iPlot Tool Operations

Many operations are available in the iPlot tool. Once you have visualized your plot data, you can scale and filter as well as creating a histogram or viewing statistics for your plot. The following operations are available for plots.

Scaling a Plot Display

iPlot allows you to scale your plotted data by selecting Operations  Transform  Scale Data. You can scale your data by a factor which you provide in the Scale Factor dialog.

Once you have set the scale factor, select OK and the scaling takes place.

Viewing a Histogram

A density histogram is a plot consisting of either horizontal or vertical bars. The widths or heights of these bars represent data values. Another type of histogram is a style plot histogram which plots different data sets side-by-side using differently styled points or bars to represent the data. To view a density histogram of plot data, use the iTool's histogram feature by selecting Operations   Histogram. For information on histogram creation, see Plotting a Histogram.

Viewing Statistics

To view statistics for plot data, use the iTool's statistics feature by selecting Operations   Statistics. For information on viewing statistics, see Displaying Statistics.
