Changing the configuration of vHW distribution plots usually causes the program to crash, especially if multiple changes are made. (Revision 1125)

By "distribution plots", you do mean the separate dialog plots that are either distributions or histograms, right? By "configuration", you mean parameters such as smoothing or sensitivity or hide histogram or hide envelope; right?

Does this happen on a Windows version? or Unix? Please describe a little bit about the input data and the nature of plots shown before the crash.

After test runs and study of the source, my understanding of the issues here are as follows.

  • In attempting to modify plots (in any application, not just vHW), clicking on Config leads to a dialog wherein any of the Update * Axis functions can cause a crash.
    • Changing scales in the Axis dialog and clicking Apply can be done multiple times with no problem.
    • The problem comes once the Close button is clicked in the Axis dialog. From the Config dialog, clicking any Update * Axis button afterwards causes a crash.
    • No other Config dialog elements seem to cause a problem.
    • The cause for the Update*Axis re-use crash has been identified in the source and can be easily fixed.
  • In vHW specifically, the Distribution/Histogram/Envelope plots always have a sedimentation coefficient ("s") minimum of zero.
    • This is no particular problem if the s maximum is in single digits.
    • For s maxima in double digits and beyond, the range is too broad, causing insufficient resolution with bunching of values at the end.
    • The fix for this is to use a plot X minimum closer to the actual s minimum present in the data.

This problem is not unique to vHW plots. Any time a plot Config action opened an Axis Configuration and later tried to re-select any Axis Configuration in the dialog, the application would crash.

This has been fixed.
