I have a set of polar plot data and need to plot and color code them as individual points. Can I do this using the polar template?
Also, I have tried converting the data to cartesian and plotted using scatter template, but encountered a problem. The angular data begins with angles of 330 degrees and runs through 0 to 150 degrees. When converting to cartesian, the y-axis automatically puts the first part of the data (330-0) to the right of the rest of the data (0-150).
Any suggestions/ideas?

Hi,
I presume what you want to do here is to assign colors to individual points using a third parameter column? If yes, that can be done using color indexing or mapping, as follows:
0> place a third column of color indexing data next to your y column
1> create your polar plot using the polar template
2> click on the "scatter" or "line+symbol" graph button to change your default polar line plot
3> use the menu Format->Plot to bring up Plot Details dialog
4> on the symbol tab, click on the Symbol Color drop-down, and change it from Automatic to Indexing, or Color Mapping, and then pick the third column as the column to base the indexing/mapping on.
As for your other transformation problem, it is not clear to me - maybe you can send your project and your transformation code to tech support?

polar - cartesian; retaining contiguous data
