You configure properties, such as whether the scale used for the y-axis is inverted, as part of the initial X-Y-Z Plot configuration (see Configure the Y-Axis Scale). Thereafter, you can make further adjustments to the axis using the Y-Axis Properties window. You can also adjust the axis using the axis's context-sensitive menu.
To invert the axis's scale using the menu:
- Display the X-Y-Z Plot in Design mode (see Display an X-Y-Z Plot in Design Mode).
- Right-click on the y-axis.
A context-sensitive menu is displayed. - Select the Adjust Axis option.
A further context-sensitive menu is displayed. - Select the Invert Scale option.
The scale shown on the y-axis inverts, so that the maximum value appears at the bottom and the minimum value at the top, or vice versa (whichever is the inverse of the present scale direction). - Either:
- Select the Save button to store the changes to the X-Y-Z Plot.
ClearSCADA updates the y-axis configuration to take into account the adjustments that have been made to the axis. - Close the X-Y-Z Plot without saving the changes if the adjustments that you have made to the y-axis are only required temporarily.
ClearSCADA discards the changes made using the menu option when the X-Y-Z Plot is closed.
- Select the Save button to store the changes to the X-Y-Z Plot.
Example:
An X-Y-Z Plot with the y-axis showing a scale of 0 to 100. The minimum value appears at the bottom of the y-axis, and the maximum value at the top.
The same X-Y-Z Plot with the y-axis scale inverted. The direction of the y-axis scale is reversed, so that the minimum value appears at the top of the y-axis, and the maximum value at the bottom. The positions of the traces' values are also inverted, so that they remain aligned with the y-axis's scale.
