Contour Plot – Options

Use this to set attributes to control the appearance of the contour plot.

Graph title

Lets you enter a title for the graph. The title appears centred at the top of the graph.

Title position

You can position the title by selecting the Centre, Left or Right option.

Enclose graph in box

Select this to draw an enclosing box around the graph.

Title font

This opens the Edit Font dialog that lets you control the font for the title.

Contours

Specifies how the contour heights are to be drawn. You can enter a list of contour heights (separated by spaces or commas) using the Contour heights option. Alternatively, you can select Interval between contours to specify an interval between each contour or Number of contours to define the exact number of contour lines required.

Invert Y-axis

This controls the orientation of the y-axis. If this is selected then the y-axis is reversed, so that the grid is in the same order as it would be if it were printed.

Colour of contours

Provides a list of colours which can be used to draw the contours lines.

Colour between contours

Specifies how to shade the areas between the contours. The colours used can be selected using the Intensity of a single colour, or a Spectrum of two colours or a Discrete colour palette. The colour range for the first two cases is displayed in the Sample field. In the later case, you can be select the palette from the drop down list of colour palettes, and when Boundary values or Interval between changes are selected, you will also need to specify the Number of intervals needed for the palette. In the later case, when Interval between contours or Contour heights are selected, you will need to specify the Number of intervals needed for the palette.

Edit all fonts as a list

Clicking this opens the Edit All Fonts as a List dialog which allows all the fonts in the graph to be set in one place.
