Contour Plot 2D

With the 2D-LC > Contour Plot 2D snippet, you add a contour plot to your report template. The contour plot is always shown by signal name.

In the Report Editor window, a generic plot is shown.

Contour Plot 2D Properties

Compounds
Show 2D peak regions	If selected, 2D peaks are shown outlined in the contour plot (see Add a 2D peak as a 2D compound to the processing method).
Show compound labels	If selected, labels are shown for identified 2D peaks (see Show compound labels in the contour plot).

Display
Enable interpolation	If selected, the contour plot is shown in interpolation mode (see Apply interpolation mode).
Show cut annotations	If selected, the cut numbers are shown at the top of the contour plot. NOTE: Cut annotations are not shown in the contour plot is full comprehensive data acquired with ChemStation.
Color map	Choose the color map as required.
Color Map Scale	Choose if you want to apply the same color gradient to all signals (default), or if you want to calculate the color gradient per pane. See Adjust colors in the Contour Plot 2D

UV Purity
Show UV purity results	If selected, the UV peak purity or impurity classifications are shown. As there no transparent coloring as in the Data Processing view (see Show UV Peak purity in the Contour Plot 2D), choose the appropriate option: Partial cut cover: displays the UV purity result on each left and right border, covering only two thirds of the cut. Full cut cover: corresponds to what you see in the Data processing view without moving the mouse pointer over the peaks.

If selected, the UV peak purity or impurity classifications are shown. As there no transparent coloring as in the Data Processing view (see Show UV Peak purity in the Contour Plot 2D), choose the appropriate option:

Partial cut cover: displays the UV purity result on each left and right border, covering only two thirds of the cut.

Full cut cover: corresponds to what you see in the Data processing view without moving the mouse pointer over the peaks.

Scaling
Use ¹D custom scale	If selected, you can configure a specific ¹D retention time range. Provide the From and To values as required. The Contour Plot 2D report item makes sure that the cuts in a given ¹D retention time range are always fully plotted. If parts of a cut are outside the given range, the range will be expanded so that all cuts are included completely. If there are no cuts at all in a given ¹D retention time range the plot area will be empty.
Use ²D custom scale	If selected, you can configure a specific ²D retention time range. Provide the From and To values as required.
