Detailed Description

Class to display a Powder Pattern (calc,obs) in a graphic window.

So far only displays calc and obs patterns.

Todo:

display the difference pattern. Allow to zoom. Display reflection positions for crystalline phases.

Member Function Documentation

void ObjCryst::WXPowderPatternGraph::OnUpdate

(

wxCommandEvent &

WXUNUSEDevent

)

Update the powder spectrum, at the user's request.

This calls the WXPowderPattern::CrystUpdate().

void ObjCryst::WXPowderPatternGraph::SetPattern	(	const CrystVector_REAL &	obs,
		const CrystVector_REAL &	calc,
		const REAL	tthetaMin,
		const REAL	tthetaStep,
		const CrystVector_REAL &	sigma,
		const CrystVector_REAL &	chi2Cumul
	)

Update the pattern.

This is called by the WXPowderPattern parent.

Deprecated:

Rather, use the new WXPowderPatternGraph::SetPattern() which takes a full vector of x coordinates rather than min & step

void ObjCryst::WXPowderPatternGraph::SetPattern	(	const CrystVector_REAL &	x,
		const CrystVector_REAL &	obs,
		const CrystVector_REAL &	calc,
		const CrystVector_REAL &	sigma,
		const CrystVector_REAL &	chi2Cumul
	)

Update the pattern.

This is called by the WXPowderPattern parent.

Member Data Documentation

RefinableObjClock ObjCryst::WXPowderPatternGraph::mClockAxisLimits

private

Clock corresponding to when the graph limits where last changed.

This is compared to PowderPattern::GetClockPowderPatternPar() to know if these parameter need to be reset.
