Properties of Graphics View (Properties Dialog)

Coordinate axes, grid and some other properties can be customized using the Properties Dialog of the Graphics View. After right clicking (Mac OS: Ctrl-click) on the drawing pad, you can open this dialog window by selecting Graphics... from the appearing Context Menu of the Graphics View.

Customizing Coordinate Axes and Grid

To show or hide the axes and the grid, right click (Mac OS: Ctrl-click) on the drawing pad and select the corresponding items Menu Axes.gif Axes or Grid.gif Grid from the appearing Context Menu. For further setting you need to open the Properties Dialog.

  • On tab Basic, you can, for example, change the line style and color of the coordinate axes, and set the the ratio between the axes . To make sure the axes ratio cannot be changed by any command or user action, you may lock it using the lock icon.
  • Clicking on tabs xAxis and yAxis allows you to customize the axes individually, set the distance of the tickmarks, labeling, axes visibility, units and more. If you want the cross of the axes to be at point (a,b), you can set Cross at parameter for xAxis to b and for yAxis to a. Option Stick to edge means that the line remains close to the bottom or left border of the screen. To draw only the part of the axis to the right or to the top of the axes intersection, you can select Positive direction only.
  • On tab Grid, you can change the color and line style of the coordinate grid, set the distance and ratio for grid lines to a certain value, and the grid visibility. Three types of grid are available: Cartesian, polar and isometric.
  • Axes scaling is possible in every mode by pressing and holding the Shift-key (PC: also Ctrl-key) while dragging the axis.
  • Range of the axes may be given dynamically, e.g. in Basic tab you can set X Min to x(A) and Y Min to y(A) to ensure the lower left corner of the view remains in point A. In such setting, the view cannot be zoomed.
