[rrd-users] No Line Graph

Hi,
There is no line graph display when I select 4 rrd files for aggregation
and display as line and area graph. There are 2 rrd files with nan
values and there is no line graph display. However, if there are values
for all the rrd files, there is line graph display. When I select 3 rrd
files with 1 rrd file having nan value, I could see the line graph. It
seems that area graph is not affected by the nan values as I could see
the area graph even for 2 rrd files with nan values.

This is puzzling. If nan value is the cause of the problem, why one rrd
file with nan value can still plot the line graph?

Pls advise. I attached 2 png files for your reference.

Thank you.

Regards.
