NavigationToolbar2Calipso¶

Custom toolbar implementation deriving from the matplotlib.backend NavigationToolbar2, The TkAgg port is not used because we specifically implement our own GUI and therefore to not want to draw the TkAgg’s navigation bar. So we declare this class and leave it mostly bare, thus nothing will be rendered to the screen but we still have access to the button functions and can bind them to our own GUI

class NavigationToolbar2CALIPSO(master, canvas, frame)[source]¶

Custom toolbar derived from matplotlib.backend, since we won’t be specifically displaying any of their provided TkGUI, we will be creating our own GUI outside of the toolbar and simply using the functions provided by NavigationToolbar2. Thus we strip the toolbar of anything GUI related

Parameters:	canvas – The main canvas of the application that will be drawn to master – The master program (Calipso)

draw_rubberband(event, x0, y0, x1, y1)[source]¶

mouse_move(event)[source]¶

The event bound to mouse motion once the plot is rendered, this function will simply display the coordinates the mouse is currently over. Custom implemented so that the coordinate system can also display ‘lat’. This is done by grabbing the axes and finding both ‘time’ and ‘latitude’ axes, then using transData to translate their coordinates to screen coordinates then back to the other axis coordinates

Parameters:	event – A matplotlib event

release(event)[source]¶
