要調整 Menu view graphics.svg 繪圖區的可見範圍,您可以使用 Mode translateview.svg 移動繪圖區工具來拖曳繪圖區,並使用下列方式來進行縮放:

    備註: 您點按的位置即為縮放中心。
  • 您可使用滑鼠滾輪來縮放 Menu view graphics.svg 繪圖區
  • 您可使用快捷鍵 Ctrl + + 放大和 Ctrl + - 縮小。
  • Menu view graphics.svg 繪圖區的空白處按滑鼠右鍵(Mac OS:Ctrl + 點按)之後,會跳出快顯功能表讓您進行縮放。
  • 您也可以在 Menu view graphics.svg 繪圖區Menu-options.svg 屬性對話窗內指定 x 軸和 y 軸的範圍(請參閱下方段落)。

顯示或隱藏物件

Menu view algebra.svg 代數區中,每個物件左方的圖示能看出目前可見狀態(顯示或隱藏)。您可直接點擊小彈珠圖示來更改物件的可見狀態。更多資訊請參閱可見狀態

繪圖區屬性(屬性對話窗)

坐標軸、格線以及其他屬性,可以在 Menu view graphics.svg 繪圖區Menu-options.svg 屬性對話窗進行調整。在 Menu view graphics.svg 繪圖區按下滑鼠右鍵(Mac OS:Ctrl + 點按)之後,從跳出的快顯功能表點選「繪圖區 ...」,即可開啟屬性對話窗。

自訂坐標軸和格線

To show or hide the axes and the grid, right click (Mac OS: Ctrl-click) on the drawing pad and select the corresponding items Stylingbar graphicsview show or hide the axes.svg Axes or Stylingbar graphicsview show or hide the grid.svg Grid from the appearing context menu. For further setting you need to open the Menu-options.svg 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.
備註:
  • 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.
