Show the code that includes your plot statement. Also, some details of what you want to plot (particularly the sizes of the variables) would help.

>>sig=load('d:/These/ABC.mat');
>>plot(sig);
??? Error using ==> plot
Not enough input arguments.

ABC.mat is the signal saved from wavelet toolbox

When you use that form of load() the result is a structure. plot() of a structure is interpreted as using the structure to pass in options. You need to plot the appropriate variable, such as

thisdata = load('d:/These/ABC.mat');
plot(thisdata.sig);
