To close all the figures run the following command: Switch the scale of the y-axis between logarithmic and linear Increase pointer size when the navigator is an imageĭecrease pointer size when the navigator is an image The following keyboard shortcuts are available when the 1D signal figure is in focus: Keyboard shortcuts available on the signal figure of 1D signal data Ĭhange coordinates for dimensions 0 and 1 (typically x and y)Ĭhange coordinates for dimensions 2 and 3Ĭhange coordinates for dimensions 4 and 5 Keys when the navigator window is selected. Is possible to change the size of the cursors by pressing the + and.
Sometimes the default size of the rectangular cursors used to navigate imagesĬan be too small to be dragged or even seen. Visualisation of a 2D spectrum image using two pointers. Note that some combinations will not work for all platforms, as some systems reserve them for Hotkeys and modifier keys for navigating the plot can be set in the Modifier keys do not work with the numpad. The defaults are Shift + left/ right and Shift + up/ down,įor navigating dimensions 2 and 3 (4 and 5) respectively. To navigate navigation dimensions larger than 2, modifier keys can be used. Navigating without using the modifier keys
To avoid the problem of changing zoom while navigating,Ĭtrl + arrows can be used instead. In matplotlib, left and right arrow keys are by default set to navigate the In s.axes_manager.indices or as calibrated coordinates inĪn extra cursor can be added by pressing the e key. The current coordinates can be either set by navigating the
When using the numpadĪrrows the PageUp and PageDown keys change the size of the step. On and the spectrum or navigator figure is selected. It isĪlso possible to move the pointer by using the numpad arrows when numlock is Or a square depending on the dimensions of the data) and drag it around. To change the current coordinates, click on the pointer (which will be a line New in version 1.4: Customizable keyboard shortcuts to navigate multi-dimensional datasets.
