I have a requirement for a multiple series line graph.
I am looking at pure javascript solutions and feel flot looks like a good option.
However the points along the line may not be continuous but I want the line to be joined.
ie
y [Jan Feb Mar Apr May Jun]
Series 1 [4 4 5 6 7]
Series 2 [5 6 7 8 9 9]
Although there is no value for Series 1 March I want flot to draw a smooth line between Feb and Apr.
I would very much appreciate your help on this.
In my experience with Flot, it will draw a smooth line between Feb and Apr, you don’t need to do anything special for that. However, if there is no data for, say, January and February, then it will make a line that starts with March, which does look a little odd, but there’s not really a good alternative (flot or otherwise) unless you extrapolate (which is riskier than interpolating).
