fill chart x-axis if data is missing

[hunyady]

Hi,
I have a search, want to show two lines of counts by min in a chart. Want to have value 0 if there is no result in some minute.
i.E.
time typ=A typ=B
12:30 100 110
12:31 100 ---
12:32 --- ---
12:33 40 50
etc.
I want to have the values of "0" at 12:32 too in my graph.
other problem:
By chart is "span=1m" not accepted, I don't have result by "chart count by typ span=1m" only by "chart count by typ"
thank you

Your text is extremely difficult to understand but maybe this is what you seek:

... | timechart span=1m count by type

[richgalloway]

Try

... | chart cont=false count by typ

or

... | fillnull value=0 typ | chart count by typ
