i am trying to draw a line from the accelerometer data.. code is as shown below

    [gx,gy,gz] = readAcc(accelerometer);
     disp(gx);
    line([0 gx],[0 0],'Color','r','LineWidth',2,'Marker','o');

but i am getting error as

    Error using line
    Ambiguous property found.
    Object Name :  line
    Property Name :  ''.
    Error in vector (line 45)
    line([0 gx],[0 0],'Color','r','LineWidth',2,'Marker','o');

what might be the cause and how to resolve this problem? it does not display any property name..

Try the full

line('XData', [0 gx], 'YData', [0 0],'Color','r','LineWidth',2,'Marker','o');

hello Walter Roberson, sorry for asking so many questions again and again, i am encountered another error.. i have 2 .m files readAcc.m and vector.m.. in command window if i type

[accData1 accData2 accData3]=readAcc(accelerometer)

i get as accData1 = 1.0100

accData2 = -0.0400

accData3 = -0.2700

but when i run vector.m file which has function call as [accData1 accData2 accData3] = readAcc(accelerometer); after that function call if put disp(accData1); i get as 51__ or something like that.. why is like that?
