change axes scales in chart at runtime

Hey,

I have a line chart. I want to change the X-axis and Y-axis scales using a script. Using onrender script beforeGeneration(), I could change the title of the chart. But how do I change the scales or the interval?

Thanks,
Aniket

hey thanks. 
I have another issue now. I have a dataset which has a column with 1000 rows. I have created a computed column with some particular 200 rows from those 1000. When I plot a line chart for this computed column, I get a horizontal line as a plot for previous rows that i have skipped, and a correct plot for those 200 rows. I dont understand why am I getting a plot for these previous rows which arent there in this computed column which I plot. Can you help? I have set the X and Y scales to Auto. Also if I set X Origin=Min Value=0 still the same thing.
