If you don't mind using ascii characters for your points you could try using the
TextListPlot  function found in the Graphics.m package.

In[1]:= <<Graphics/Graphics.m

In[2]:= xdata1= {1,2,3,4}; xdata2 = {1,2,3,4};

In[3]:= ydata1= {1,2,3,4}; ydata2 = {1,4,9,16};

In[4]:= symbol1 = Table[ "+" ,{ Length[xdata1] } ];

In[5]:= symbol2 = Table[ "*" ,{ Length[xdata2] } ];

In[6]:= data1 = Transpose[ {xdata1, ydata1, symbol1} ];

In[7]:= data2 = Transpose[ {xdata2, ydata2, symbol2} ];

In[8]:= dataplot1=TextListPlot[data1];

In[9]:= dataplot2= TextListPlot[data2];

In[10]:= Show[dataplot1,dataplot2]

If you want the points connected or overlayed with curve fits you can make additional
plots and put them all together and set options with Show.

To get at special ascii characters you can use FromASCII[n] or FromASSCII[16^^hex]

I hope this is of some help.
