MATLAB: How to change the data cursor size, colour and shape

figureMATLABplotting

I am trying to change the data cursor size, colour and shape using the following code. 
fig=gcf;
dcm_obj = datacursormode(fig);
set(dcm_obj,'enable','on','UpdateFcn',@data_tips)
hTarget = handle(fig);
hDatatip = cursorMode.createDatatip(hTarget);
set(hDatatip, 'MarkerSize',5, 'MarkerFaceColor','none', ...
              'MarkerEdgeColor','k', 'Marker','o','HitTest','off');
However, I receive the following error:
Undefined variable "cursorMode" or class "cursorMode.createDatatip".
Error in figure_plotter (line 10)
hDatatip = cursorMode.createDatatip(hTarget);
Can anyone advise on the answer to my question, particularly by modifying the above code?

You can change the properties of Data Cursor using the following commands:
alldatacursors = findall(gcf, 'type', 'hggroup', '-property', 'FontSize');
set(alldatacursors,'FontSize',12);
set(alldatacursors,'FontName','Times');
set(alldatacursors, 'FontWeight', 'bold');
