Edit axes

When you choose the menu item EditAxes..., the dialog shown below will appear. In this dialog you can configure all options which are related to the axes. The dialog contains 4 tab sheets. The first sheet, shown below, contains options for the x-axis. The tab with options for the y-axis is completely analog to this.

x-axis/y-axis

Minimum

This is the lowest value on the selected axis. Default: -10

Maximum

This is the highest value on the selected axis. Default: 10

Tick unit

This is the distance between the tick marks on the selected axis. Tick marks are shown as small lines perpendicular to the axis. Tick unit is used for both tick marks and for showing numbers. With a logarithmic axis the Tick unit indicates the factor between the markers. For example Tick unit set to 4 will show 1, 4, 16, 64, etc. on a logarithmic axis while it will show 0, 4, 8, 12, etc. on a normal axis.

Grid unit

This is the distance between the gridlines perpendicular to the axis. This is only used if grid lines are shown.

Logarithmic scale

Check this field if you want the axis to be scaled logarithmically.

Show numbers

When this field is checked numbers are shown on the axis with the distance chosen under Tick unit.

Label

When this field is checked, the text in the edit box will be shown just above the x-axis in the right side of the coordinate system. For the y-axis, the text will be shown at the top to the right of the axis. You may use this to show what unit is used for the axes.

The x-axis crosses at / The y-axis crosses at:

This is the coordinate where the axis will cross the other axis. This is only used when Axes style is Crossed. Default: 0

Auto tick

When checked the program will automatically choose a value for Tick unit that is fitting for the axes dimensions and size of the graphing area.

Auto grid

When checked, Grid unit will have the same value as Tick unit.

Show ticks

When this field is checked, tick marks are shown as small lines on the axis with the distance chosen under Tick unit.

Show grid

When this field is checked, grid lines will be shown as dotted lines perpendicular to the axis with the color chosen under Font and color and with the distance chosen at Grid unit.

Show as a multiple of π

When this is enabled the numbers on the axis are shown as fractions multiplied by π, for example 3π/2. Show numbers must be enabled for this option to be available.

Settings

Title

Here you can enter a title that is shown above the coordinate system. Use the button to the right to change the font.

Show legend

Check this to show the legend with a list of functions and point series in the upper right corner of the coordinate system. You may change the font under Font and color.

Legend placement

Here you may choose in which of the four corners you want the legend to be placed. You can also change this by right clicking on the legend in the graphing area.

Calculate with complex numbers

Check this field to use complex numbers for calculations while drawing graphs. This will increase the time for drawing graphs but may be necessary in rare situations where the intermediate result are complex. The final result must be real for the graph to be drawn. This will not interfere with evaluations.

Axes style

Select None if you don't want the axes to be shown. Select Crossed if you want a normal coordinate system. The location of the axes may be changed from The y-axis crosses at and The x-axis crosses at. Select Boxed if you want the axes to be shown at the bottom and left side of the coordinate system, which will overwrite The y-axis crosses at / The x-axis crosses at.

Trigonometry

Choose whether trigonometric functions should calculate in Radian or Degree. This is also used for showing complex numbers in the polar format.

Font and color

Colors

You may change the background color, the color of the axes and the color used for drawing grid lines.

Fonts

You may change the fonts used to show axes labels, the font to draw numbers at the axes, and the font used for the legend.

Save as default

Check this to save all the current settings in the dialog to be used as default in the future. These settings are used the next time you choose to create a new coordinate system. The default settings are stored in your Windows user profile, i.e. each Windows user will have his/her own default settings in Graph.
