Callbacks for the Plotting Buttons

The callbacks for the plotting buttons call get_var_names to get the names of

the variables to plot and then call

evalin to execute the plot commands in the

base workspace.

For example, here is the callback for the

plot function:

function plot_button_Callback(hObject, eventdata, handles)

[x,y] = get_var_names(handles);

evalin('base',['plot(' x ',' y ')'])

The command to evaluate is created by concatenating the strings and variables

that result in the command:

plot(x,y)
