[ncl-talk] tmYLFormat deleting trailing zero for a panel plot

[Lijun Diao]

Hi, Mary:

That is exactly what I did. But for another array as (/0,0.7,1.4, 2.1,2,8/). I set “@f” and then the labels appear as I want automatically. The only difference between the two arrays is that the maximum value for the first array (/0.0, 0.2,0.4,0.6,0.8/) is less than 1, while the other larger than 1. 

thanks,

My apologies, I misunderstood that you wanted to take off the ".0" for the "0.0" label.

I don't think you can mix and match tickmark formatting simply by setting tmXBLabelFormat.  If you explicitly want "0" for "0.0", but "0.7" for ".7" then you will need to do something like this:

xaxis_values = (/0,0.2,0.4,0.6,0.8/) 
xaxis_labels = sprintf("%2.1f",xaxis_values)
xaxis_labels(0) = "0"    ; explictly change the first label


res at tmXBMode = "Explicit"
res at tmXBValues = xaxis_values
res at tmXBLabels = xaxis_labels

  Hi, Mary: 

  As the example shows, 0f still has 0.0 not 0 as I wanted. I already set the labels explicitly. I just wonder why for one array, it appears 0.0 while for the other 0. 

  thanks,

    This is not a panel plot issue per se.  When you create the individual plots is when you need to fix the labels the way you want them. 

    Did you see example tm_8.ncl at:

    http://www.ncl.ucar.edu/Applications/tickmarks.shtml#ex8


    This shows the different formats you can use.  I would try "0f".

      Hi, all:

      I have a panel plot and try to set the number format of the y-axes . I attached two axes from two subplots. For the left one, minimum value zero is outputed as “0.0”, while for the right one “0”. I set them use the same tmYLFormat = "@f". So my question is how can I set the starting number of the first axis also to be “0”. By the way, I need “0.7” not “.7”

      thanks,
