Thanks to all who replied to my request for techniques with which to display multiple thematic pie charts. Rob Glazier: I hope to create a map which compares market share by age group against population distribution by age group. This would display, within each ZIP code, two pies. Has anyone done this before or, have any idea how I could pull it off? What is stumping me is how I can reposition the pies after they are created. I tried the archives and various manuals without success so I'm sending up the signal, HELP! Sheila Quan: Within the thematic map set up, you can offset the positions of the pies i.e. centre, left, right, top left, top right etc. So for example you could offset one layer to the left middle and the other layer to the right middle. Another alternative would be to alter the actual centroid location. So for example you have the original layer with the original centroid location. You can reveal the centroid location by going into Layer control and turning on the "Show Centroids" under Display control. The centroid will appear as a blue square somewhere in the middle of each of your areas. If you make a copy of the original file and by making that layer editable and switching on the nodes options and show centroids, you can move the centroid location somewhere else. This means that if you now do a pie thematic map based on the copy, the pies will be pivoted based on the relocated centroid location and not the original centroid location. Hope that is clear! Good Luck. Jacques Paris The pies are attached to the centroids. The only way you can display two non-overlapping pies for the same "point" is to duplicate the map and set different centroids for each "point", then display both thematic in the same mapper. To move centroids around, in the layer control>display check show centroids (towards the bottom of the dialog); make your layer editable, select an object, use reshape (Ctrl-R) select and drag the centroid. Etc.... and on both maps! Good luck and even more, patience Mark Crompton: Does CentroidX(obj) & CentroidY(obj) for each ZIP code boundary provide a lat/long position. If so you can move the pies around from a central location, use a calculated offset based upon ZIP code size and pie diameter to spread them. I think that there may be a function somewhere to place 2 objects on the same point and then move them, but I cannot remember. The easy solution was to copy the ZIP file and manually move the centroids. Let me say that MAPINFO-L is a tremendous resource without which I would be forever fumbling in the dark.
