Public Members

• bool ShowRaw - get/set to indicate whether raw data is displayed
• bool ShowBaseline - get/set to indicate whether baseline data is displayed
• bool ShowBaseCurve - get/set to indicate whether baseline curve is displayed
• bool ShowDenoised - get/set to indicate whether denoised data is displayed
• bool ShowPeaks - get/set to indicate whether peaks are displayed
• bool ShowCentroids - get/set to indicate whether centroids are displayed
• bool ShowBins - get/set to indicate whether bins are displayed
• RectF ZoomRegion - the rectangle, in real coordinates, that represents the current view of the panel
• int ResFactor - the resolution factor of the picture, that is, how much information to leave out while sampling points

Public Methods

• SetSpectraVisiblity(string SpectraName, bool isVisible) - set visibility of given spectra.

Protected Methods

• PointF RealToWindow(float x, float y) - returns a point in window coordinates based on the real coordinates.
  • If either x or y are off the window, that dimension should be translated into float.Infinity or float.NegativeInfinity in the returned point.

• PointF WindowToReal(float x, float y) - returns the indicated point from the window coordinate system to the 'real' system.
  • Any points outside the ZoomRegion should be just set to the boundary of the ZoomRegion.

• PointF[] GetRangedPoints(SpectraData spectra, SpectraData.DisplayableTypes type)- returns a set of points less than or equal to the number of points that exist in the SpectraData for that DisplayableType for faster graphical processing
  1. Have a "range size" based on total range represented by the window / (actual pixels available * resolution factor)
  2. If range size > value (to be determined based on experimenting) return all points within window range
  3. Try to find a point in the middle of this range for the spectra to display
     • If no point is available, grab next point in sucession
     • If next point is greater than the median value of the next range, skip next range
     • Skip as many ranges as necessary
  4. Return 'valid points'

Remarks

• "real coordinates" refer to coordinates as given from the data. "window coordinates" refer to the real coordinates as translated on to the current window
