Re: Layout of label bar in PyNgl

Hi Daran,

I've been playing with your script, and I think a quick workaround
is to set panelres_at_gsnPanelBotton to a value like 0.07, which will
give you more space at the bottom for your labelbar and the
vector plot annotation.

The paneling routine should have left room for your title, so I'm
not sure why it didn't. We'll have to look into this.

Also, there's a special resource for setting the font height for
the panel labelbar, and that is:

     nglPanelLabelBarLabelFontHeightF

Again, though, the paneling routine should have also recognized
lbLabelFontHeightF. I'll look into this.

Meanwhile, I got your labelbar to look a little better. I'm not sure
exactly what panel resources you wanted to keep, but I've included
below what I used in your script (I'm a bit anal so I sorted them by
type). I removed some of the ones you had if they were redundant or
non-applicable.

If you still can't get the panels to look quite right, let me know.

     # Set up labelbar resources.
     panelres = ngl.Resources()

     panelres.nglPaperOrientation = 'Portrait'

     panelres.nglPanelTop = 0.95
     panelres.nglPanelBottom = 0.07

     panelres.nglPanelFigureStrings = t_label
     panelres.nglPanelFigureStringsFontHeightF = 0.0125
     panelres.nglPanelFigureStringsJust = 'TopLeft'

     panelres.nglPanelLabelBar = True # Turn on panel labelbar
     panelres.nglPanelLabelBarWidthF = 0.7 # Width of labelbar
     panelres.nglPanelLabelBarHeightF = 0.10 # Height of labelbar
     panelres.nglPanelLabelBarLabelFontHeightF = 0.0125

     panelres.lbRasterFillOn = True
     panelres.lbBoxLineThicknessF = 2.5

     panelres.lbTitleString = 'Reccurence frequency (days)'
     panelres.lbTitleFont = 'helvetica-bold'
     panelres.lbTitleFontHeightF = 0.015
     panelres.lbTitleOffsetF = 0.01

     # Draw 4 rows and 3 columns of plots.
     ngl.panel(wks, plot, [4,3], panelres)

Have a great weekend!
