Adding missing values in the legend when using heatmap

[Ceciestunnomtemporaire]

Hi,

I am using the Template and the Sgrender procedures to create a heatmap graphic. I have some missing values in my data, and I use the white color to see them. I would like to add this color next to the heatmap legend so other people would know that white=missing, but I did not find a way to do this.

If anyone has an idea, I would really appreciate it.

Thanks!

I haven't done this myself, but look at the LEGENDITEM statement.  The example at the end looks like you ought to be able to do something like this (untested):

legenditem type=marker name="missingVal" / markerattrs=(color=white symbol=squarefilled size=14)

                  label="Missing Value";

Then use a DISCRETELEGEND statement inside the LAYOUT OVERLAY to place the missing value swatch where you want it.

Of course, the simpler way is to use TITLE2 or FOOTNOTE  🙂

footnote "The color white represents a missing value";

Yes it's working fine. I just had to add a slash before "markerattrs".

Thanks and have a great day !
