Re: the legend order

Thanks Adam.

That's great. It has taken me so much time to fix it yesterday. Changing
lgres@lgMarkerColors to lgLineColors fixed my problem. Thank you so much.

Hello,
I think you are setting the wrong resource. Instead of setting
lgMarkerColors (which control the marker colors of the legend), try setting
lgLineColors. See example #8 here:

Hi,

When I set up the legend, I have a strange problem. The lables of legend are
supposed to match with the colors, ie LE_OBS: red, LE_CTL: green,LE_BT:
black. But I got a disordered legend. Please see the attached file.

And the script is as below.

How can I fix the problem? Thanks.
