13.3.4.5 GraphLogView Functions

The GraphLogView provides the following functions:

UpdateLineFeatures()

Updates the features of the Lines in accordance with the values on the viewspec

SetLineFeatures(ColorType color_type, SequenceType sequence_1, SequenceType sequence_2, SequenceType sequence_3, bool visible_only)

Sets the features of the all the lines or only the visible lines if visible_only is set. The lines' features are determined by iterating over the possible choices in sequence_1, and then when those choices are exhausted, incrementing sequence_2 and repeating the possible choices in sequence_1 again. This is likewise extended to sequence_3 if need be until all of the lines' features have been set. The color_type argument is used to determine the colorscale to sequence over for the sequence arguments which are set to COLORS. The other possible choices of sequence types are LINES and POINTS.

SetBackGround(RGBA background)

Sets the graph area's background color. When printing the graph it is useful to set this color to white.

SetXAxis (char* nm)

Sets the x-axis_index of the view to the field named nm. If there is no field named nm then the index is unchanged.
