I made a maplet with the MapletBuilder for displaying a worldmap or - if requested - a globe with locations of earthquakes in a selected period of time. Before that I programmed a maple worksheet to this subject.
The maplet is build like this:
First there is a Plotter-Window followed by two Radiobuttons for choosing between two different graphic renditions (2D and 3D).
For choosing a period of time I used DropDownBoxes.
The starting date and finish date consist of 3 Boxes each to choose month, day and year separately.
To confirm the dates and to plot the relevant map there's a ClickButton.
I'm searching for a useful guide of the MapletBuilder (for Maple 11).
I know how to create Boxes 'n' Stuff. Now I want to assign commands to the buttons,which should be executed by pushing them but I don't know how to do that. By that I mean where to put them and what kind of commands exist or do I have to use.
I need a guide with some examples.
It would be great if anyone could help me.
I'm working on a globe right now with worldmap, equator,0°- and 90° meridian on it.
Now I want to display a point on it in the form of a circle.
The point is given in longitude and latitude values, for example lon: -21.5750 and lat: -60.9340.
How do I do that?
If it helps, here the equation of the globe:
Globe:= (lon,lat) ->(cos(lon)*cos(lat), sin(lon)*cos(lat), sin(lat));
Can someone help me please?
