And exactly what commands were you using?Hi, I think I can't use FILL/CONTOUR because it's not a 2-dimensional plot? I get an error if i change shade for fill... I am ploting height (y-axis) Vs xlong in a concrete point of latitude. Is there another way to smooth the image? I have used the LABEL comand to put the name of the place that I need where I need (I have used label/nouser ...and inches) Now, I would like to plot a meteorological tower of 100 m (a little stick in my graphic) in some concrete position.. Can I do it? I would like to use a predefined image, but I can also use only a kind of stick. I think I am going to need a posprocessing tool to do it.. There's nothing wrong with working with your image with a postprocessing graphics tool. Or you might use the POLYGON command to put an image on your plot. For example, yes? use etopo20You can define your own shape as well. There are a bunch of them defined in the script polyshape, so for ideas look there, yes? go/help polyshapeYou could use the polygon command itself, or stay with the polymark script - it's the easiest to use as it does the scaling for you. If you want to define your own shape, you can make your own polyshape.jnl script, and keep it in a local directory where Ferret will find it before it finds the polyshape script that's part of the Ferret distribution. Thank you very much for all Carlos Román Cascón On Fri, 2011-07-22 at 10:15 -0700, Ansley Manke wrote:Hi Have you looked at your plots using the FILL command instead of SHADE? See the LABEL command which lets you put a label anywhere on the plot, using either user-coordinates (longitude and height) or page coordinates, which are "inches" relative to the plot surface. There are a number of color scales available, look at "palette" in the documentation. Ferret includes many pre-defined palettes, and you can create your own customized palettes. There are several FAQ's about color palettes; look in the "Custom Plots" section of the FAQ's. There are limited things within Ferret to do about changing the background color. You can change the background color to black, "go black". There are various tricks to making a background color, and we could talk about that more in another message, but your easiest solution right now might be to use a post-processing image software to change white to another color. I'm not entirely sure what you want to do differently about the coordinates. You are using the curvilinear form of the SHADE command. Is your data on a truly curvilinear grid? That is, does the variable xlong vary in the y direction, or is it only a function of longitude? If it's only a function of longitude and height is only a function of height then you could define coordinate axes from those coordinate variables. yes? define axis/x/units=degrees_east xaxis = xlong[j=1] yes? define axis/y/units="`height,return=units`" yaxis = height[i=1] yes? let/units="your definition of the units" cloudvar = 1000*qcloud[x=xaxis@asn,y=yaxis@asn] On 7/22/2011 2:51 AM, Carlos Román Cascón wrote:Hi, I would like to "smooth" the attached image (the qcloud output), in order not to see the "lines" separating points of the grid in vertical levels and horizontal resolution. I don't know if it's possible with Ferret. I would also like to put a name of a place ("Investigation centre") in a concrete point of the surface in the graphic and change the colour of the surface (the white part). I would also like to specify the colour of the colorbar, for example, I want the surface (now white) in brown and the 0-0.5 part (pink part) in clear blue or white... I don't know how to handle the axis in coordenates instead of grid points in Ferret. I think I have to use a post-processing tool of WRF to do it, but I don't know which one I should use. This is the code I use. use 15julio.nc set region /i=0:120/j=60 let height=(PH+PHB)/9.81 REPEAT/l=1:40 (shade /vlim=670:1400/lev="(0,1,0.05)" qcloud*1000, xlong, height; plot /nolab /over /line /vs xlong,hgt/1000; frame/file=dibujo`l`.gif) There are a lot of question, but you always solve my doubts.
