Highlight a data point on all graphs
Posted April 10th, 2009 by aclightUsing the code below, you will be able to Shift-click on specified graph windows to have the data point on the trace under the mouse pointer (if there is one) be highlighted with a tag on all other graphs on which that same wave is displayed. This currently will probably not work on traces displayed using XY pairs, and may not work on images or more complicated graphs.
Cluster a correlation matrix
Posted April 8th, 2009 by RGerkinThis code demonstrates how you can cluster data using the correlation matrix.
// Create a correlation matrix from fake data, in this case with 2 embedded patterns and // relative noise of 0.25. FakeCorrelationMatrix(2,0.25) // Cluster the correlation matrix with 2 expected patterns. // Picks starting cluster guesses randomly and for high values of noise it might give a poor // result. The /SEED=(ticks) flag makes it give random initial guesses on each run. CorrelationClustering(2,Fake_Corr_Matrix)

A filtered list of all controls in a window, including subwindows
Posted February 28th, 2009 by harneitThis might be interesting for you if you are programming Igor Pro user interfaces.
If you have ever tried to make your functions aware of subwindows, you might have missed a function that returns a list of all controls in a window, regardless of whether they are in the main window or in a subwindow. The function given below is highly configurable (you can filter by match strings and/or control types, recurse through child windows...), please consult the comments in the snippet.
SubWindowList
Posted February 28th, 2009 by harneitThis might be interesting for you if you are programming Igor Pro user interfaces.
If you have ever tried to make your functions aware of subwindows, you might have missed a function that returns a list of all child windows of a (sub)window with full host specs. The built-in function ChildWindowList only returns "immediate subwindow window names", and does not include the full "host spec path".
print SubWindowList("graph0") prints something like graph0;graph0#G0;graph0#P0;graph0#P0#G0;graph0#P1
whereas print ChildWindowList("graph0") would print G0;P0;P1;

The first fully functional release.
The coordinate system issue has been resolved, now both "relative" and "absolute" coordinates are ok.
Not tested on Mac, but I'm waiting to hear complaints...
Interactive Dartboard IGOR.6.03.x-0.99-a

This is the first release. A minor issue about coordinate systems persists, so the version number is 0.99a.
Tested on IP6.03(Win). May not work on Macs due to the outstanding minor issue.
Minor issue: Problem translating mouse coordinates (pixels) to window coordinates (points).
Current workaround: hard-wired the dartboard to be centered in its window.
DrawArcWedge
Posted February 14th, 2009 by harneit
DrawArcWedge draws an "arced" wedge, i.e. a polygon delimited by two concentric arcs. A more elaborate example that uses DrawArcWedge can be found in my project Interactive Dartboard. Note: This was designed and tested in IP6.03 on Win, but should also work in Igor 5.x, and on Mac.
