The x-coordinate and the value axis can be arranged horizontally or vertically depending on the orientation of the display. You can assign a name and a unit to both. For both axes, the major and minor ticks shall be configured.

Flipping a horizontal axis means that the smallest value will be positioned on the right side and the highest value on the left side. Flipping a vertical axis means that the smallest value will be displayed on top and the highest value at the bottom.

Two modes are available for the base axis:

• • Absolute This mode was especially developed for technological cross profile displays in the steel industry, such as flatness profiles, strip tension profiles or temperature profiles. You can set up the rolling mill width (= width of bar graph) and values for major and minor tick marks on the axis given in the unit specified in the corresponding entry field (mm, cm, etc.). The number of bars as specified in the Bar chart dialog is distributed over the base axis. The width of the bars itself can be adjusted in the Bar Values dialog in the properties tree.

  • Relative This mode should be used if no metrical relation is required on the base axis, e.g. for a filling degree display. The number of bars as specified in the Bar chart dialog is always distributed over the entire base axis. In this mode, you can only specify the axis title and the major ticks.

For the base axis (x-coordinate), the bar width has to be specified. With enabling the option Center around zero, the bars will be placed symmetrically to a zero point in the middle; not only on the negative side, but also on the positive side. If this option is not enabled, the bars will be assigned in positive ranges only, as displayed in the following image.
