Axes Tab

Using the tab "Axes", all properties of axes can be set.

Axes in the diagram – The possible axes of a diagram are specified in this list – column "name". In the column "Show" a check is shown if the axis is drawn in the diagram. The axis can be switched from Show to Hide by double-clicking in the column. Different axes have been defined for different diagram forms. For each of these diagram forms 1 or several x and y axes exist. The following axes were defined:
- Stretched length – Numeric axle with the length scale for the profile-plot.
- Node name-? – Text axes for representing node names along the paths.
- The min-max value of these axes is not adjustable and is transferred from the axis stretched length.
- Pressure height – Numerical axis on which the positive pressure of a node over terrain height, converted to height, is represented.
- The conversion takes place with the material data of the node, i.e., at local pressure and temperature.
- Hydraulic pressure (abs) – Is the absolute pressure at a node is plus the pressure due to terrain height related to 0 m.
- Terrain height is converted to an equivalent pressure height using average density. A density value of 970 kg/m³ is preset
- Pressure at rest height – Is established from the information about the pressure maintenance from the network calculation and is the pressure height at the pressure maintenance node.
- During average pressure maintenance, the pressure heights of the two pressure maintenance nodes are weighted according to the average pressure factor.
- Temperature – For the application of the node temperature.
- Speed – For the application of flow speeds in pipings.
- Mass flow – For the application of the mass flow.
Axis attributes – The properties of the axes are different for numerical and text axes. The following list shows first the properties of the numerical axes. Following that, the differences from text axes are described. In principle it is valid that fields without entry are automatically filled by sisHYD. The sisHYD automatism can be controlled with entries.
- Range
  - Minimum – The minimum value of the axis.
  - Maximum – The maximum value of the axis.
  - Main interval – Distance between marked main scaling lines. The numerical value must be greater than 0 and a multiple of the fine division.
  - Auxiliary interval Distance of the short scaling lines from each other. The numerical value must be greater than 0.
  - Formatting – Names the number of decimal points for the text of the main division.
- Styles
  - Axis line – Line style for the axis line.
  - Main interval – Style for the scaling line of the main division.
  - Auxiliary interval – Style for the scaling line of the fine division.
  - Main grid network Style for the grid line within the diagram surface which represents an extension of the long scaling line – main division.
  - Auxiliary grid network Style for the grid line within the diagram surface, which represents an extension of the short scaling line – fine division.
  - Text – Text style for the text of the main scaling line.
  - Axis title – Text style for the title of the axis.
- Dimensions/lengths
  - Length Main interval line – Length of the scaling line with which the main interval is marked on the axis.
  - Length Auxiliary interval line – Length of the scaling line with which the auxiliary interval is marked on the axis.
  - Distance previous axis – Distance to the previous axis (if available).
  - Distance Text – Distance between axis line and the text for the main interval.
  - Distance axis title – Distance of the axis title from the maximum value of the axis.
- Representation
  - Axis reflect – Axis is drawn at the opposite edge of normal representation reflected representation the axis framework.
    - Mirror axis divides the axes-range (red)
  - Axis line – Draw axis line. This attribute is mostly set to "no" for text axes.
  - Text Main interval – Switches the output of text on the main division on or off.
  - Axis title – Draw/hide the axis designation.
  - Main interval line – Draw/hide the scaling lines for the main interval.
  - Auxiliary interval line – Draw/hide the scaling lines for the auxiliary interval.
  - Main grid network – Draw/hide the auxiliary grid network aligned at the main interval line.
  - Auxiliary grid network – Draw/hide the auxiliary grid network aligned at the auxiliary interval line.
