Axes

Add axes to plots.

Axis attributes such as labels, color, and scaling can be modified using the Axes panel. The panel is displayed when the Axes button is selected from the Annotations toolbar, when you select Axes from the Annotations menu, or when you click on an axis label in a HyperGraph 3D window.

Apply to

You can apply your selections at any point to the Selected axis or to All Axes.

Selected axis: Applies each change to only the axis of the active tab.
All axes: Applies each change to the X, Y, and Z axes.

Across

You can apply your selections to the Current plot, the Current page, or All Pages.

With label: Located under All Pages, With label only applies each change to the axes that contain the label specified in the With label entry field.

X, Y, and Z Axis Tabs

From the X Axis, Y Axis, or Z Axis tabs, you can apply and edit axis attributes.

Label

The axis label is a single line of text displayed alongside the axis in HyperGraph 3D. It is automatically updated in HyperGraph 3D when you enter a new name in the Label field.

Click the font button,

, to change the axis label's font.

Import templates can be written that specify the text for axis labels. This enables axis labels to be automatically included when plots are constructed using the Reports panel.

Scales

Axes can be represented by a Linear, Logarithmic, dB10, or dB20 scale. A different scale can represent each axis. Use the radio buttons to select the appropriate scale for each axis.

dB10: HyperGraph 3D scales any curve data using the formula Data = 10.0 * log10(Original_Data). If no curves exist on the graph, the minimum value will default to -30 and the maximum to 10.
dB20: Curve data is scaled using the formula Data = 20.0 * log10(Original_Data). If no curves exist on the graph, the minimum value will default to -60 and the maximum to 20.

Minimum and Maximum Values

When a curve is constructed, the axis minimum and maximum values are set so that the curve fits in the window by default. When you select a different axis scale type, the minimum and maximum values automatically change.

Min and Max: New minimum and maximum values can be specified in these fields. Altering the minimum and maximum values for an axis scales the plot along that axis.; Click Fit on the plotting view controls to return Min and Max to the default values and scale the curve to fit the window.
Auto fit: The selected axis is automatically scaled to fit new curves or bar charts that are added to the axis.
Fit range: Restores the current axes values when Fit is selected from the view controls.

Font Properties

Click the font button,

, to change the font, font style, and size of the scale type values.

Color Palette

Any of the 64 colors can be assigned to the plot axes. After selecting an axis, select a color from the palette to instantly change the color of the axis.

Axis Tics

Tics per axis

The number of tics on each axis (or tics per decade if the axis is logarithmic, decibels, or dB10) is controlled by entering a specific number or increment.

From the drop-down menu, select Tics per axis to add a specific number of tics. Select Tic increment to add tics at specific intervals. Enter a value in each text field or use the buttons to change the current values incrementally.

Grids per tic

If using the linear axis, use Grids per Tic (or Grids per decade if the axis is logarithmic, decibels, or dB10) to change the number of grid lines on the graph.

Precision

Both fixed decimal format and scientific notation display numbers to the right of the decimal point. The accuracy of each format can be adjusted by entering a value in the Precision text field or using the buttons to select a number. Precision specifies the number of digits displayed to the right of the decimal point.

Tic Format

Axis values can be displayed using one of three formats. Use the Tic Format drop-down menu to select one of the following:

Auto format: Determines the best format for displaying axis values and truncates trailing zeros.
Scientific: Expresses values in exponential form.
Fixed format: Expresses values using a specified number of decimal places.

Shading

Use the Shading tab to change the grid attributes, the background color, and the axes length.

Grid style

Grid styles can be used to change the shading style of the grid. Click on a shading style button to instantly change the grid style. Options include box or line.

Grid line color

Select a color from the palette to instantly change the grid line and wireframe colors.

Background color

Select a color from the palette to change the color of the 3D box.

Note: See Preference Files for more information on specifying defaults in the preferences.mvw file.

Axes lengths

Automatic: HyperGraph 3D automatically adjusts the display of the axes lengths to fill the graphics area.
Manual: Use the slider bars to adjust the relative lengths of the axes in the display. You can also add the new length value directly into the text field.
