Tools> Histogram of Measurements
Plots a histogram from a .CSV or .TXT file of previously-made measurements. These files can be output from tools such as Measure Features, Color By Measurements, and Local Measurements.
- To begin, load previously generated measurements. These must be .TXT or .CSV files with continuous rows and columns.
2. Load, Export
- Load: You can start over and create a new histogram image by loading a new feature measurements file.
- Export: You can export the existing feature measurements results to a spreadsheet.
3. Measurement Stats
Displays the mean, standard deviation, min, and max of the selected measurements.
Determines the number of bins to divide the histogram into. The default value is auto-calculated to provide an effective histogram shape. Typing in a new value sets a manual number of bins. Erase the typed in value anytime to revert back to the auto-calculated value.
5. Export Data, Save Plot
- Export Data: Export histogram data to spreadsheet.
- Save Plot: Save plot as image.
6. Unfold Histogram
Estimates the shape of the 3D histogram which underlies the original . Launches a window which explains the process and requirements, and allows selection of the input and output measurements.
7. Input and Output Measurements
- Input Measurements: Select the type of measurements to be unfolded. Choose between Equivalent Diameters or Areas.
- Output Measurements: Select the type of measurements to output from the unfolding. Choose between Equivalent Diameters or Volumes.
8. Original, Unfolded, and Edit
- Original: Show original histogram.
- Unfolded: Show unfolded histogram.
- Edit: Edit histogram unfolding parameters
