Lately I've been attempting to change a data set that has a line plot object associated with it (which has already been drawn on the graph). My method consists of calling "WGFreeDataSet", creating a new data set object (with more points than the original), and then calling "WGRedrawGraph". Unfortunately, the line plot doesn't change (in appearance, the new points aren't drawn), but when I double click on the line and bring up the data editing table I can see that the new data set there.
What am I doing wrong? Do I need to delete the plot object associated with the original data set, and create a new plot with the new data set?
Thanks. |
