Back to standard editing mode |
The pointer gets the usual shape of an arrow and you get back into the normal editing mode, in which you can select and edit elements in the editor window. |
2 |
Panning tool |
The pointer gets the shape of crossed arrows. You can click somewhere in the editor window and - while keeping the mouse-button pressed - shift the visible area of the chart within the window. |
3 |
Magnifier tool |
This function is useful when you have zoomed down the displayed chart to less than 100%. It opens a subwindow in the lower right corner of the editor window. As long as you move the pointer over your chart, this subwindow shows the respective part of the chart in 100% size. If you now click the window, the subwindow closes and that segment of the chart which was shown in the subwindow, is displayed in 100% size. So, if you want to keep the previously set zoom factor, use the Back to standard editing mode button to get back to the normal editing mode. ![]()
