<div dir="ltr">Hi Laura,<div>I don't believe you received an answer to your question. You asked whether setting cnFillMode = "RasterFill" will change the number of grid cells that are filled when there is missing data. The answer is yes. When you set cnFillMode = "RasterFill", every grid cell that is not set to _FillValue will be filled. When cnFillMode = "AreaFill" (the default), NCL will look at the values of the neighboring grid cells when shading the center grid cell. If not enough neighboring grid cells have data then NCL will not fill the center grid cell. Thus, if you want to color fill all valid grid cells you should set cnFillMode = "RasterFill".</div><div>Adam </div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Sep 20, 2018 at 2:22 PM Laura Fowler <<a href="mailto:laura@ucar.edu">laura@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hello:</div><div><br></div><div>I am trying to plot the index level of the cloud base of shallow convection for one time step.
