[gradsusr] shaded plots and boundary

[Srivatsan Vijayaraghavan]

Hi all,

I have a similar problem with shaded plots. When I plot small regions or big regions (sample figures attached), the boundary is slightly away from the shaded region.

How do I fix this ?

Thanks,

Sri

You have to 'set csmooth on' to make the contour lines exactly match the shaded contours. The differences are especially noticeable with low resolution grids. --Jennifer

Dear Gradsusr members:
          I am new to Grads,and I have a problem in using it. The thing is about contouring:
    the boundary of shaded contour area doesn't match the contour line accurately.
    with the following steps, you will replicate this problem:
    1) open model.ctl
    2) set gxout shaded
    3) display ts
    4) set gxout contour
    5) display ts

    For example, if you check out the contour line of value 300 from longitude 0W to 120W, you can find the unmatched phenomenon.
    I am wodering that if there are any options in Grads to solve this problem. Thanks a lot!
    Yours sincerely!
