I want to create a graph showing trends over time, calculated from a formula of various data.
However, some data is missing, resulting in zeroes in the calculated data which the chart uses.
When plotting this data against as a line graph, it's drawing a line down to the axis, which I don't want.
I'd like either a gap in the line, or skip the data point and draw from directly previous to next.
i.e. given this data:
00.0 61.6 39.5 74.6 86.8 72.0 66.5 99.5 85.6 80.6 95.0 122.4 81.0 83.1 88.2 00.0 94.3 60.5 00.0 99.5 95.8 86.2 00.0 111.4 84.1 110.8 78.9 62.0 75.9 102.2 89.9 87.1 81.6 73.5 00.0 116.9
All the 00.0 items mean "no data", so I'd like them ignored (not treated as 0 value).
This is the chart I currently have:
This is how I'd like the chart to come out:
Again, I don't mind if the dotted lines are blank or solid, so long as they don't go down to zero.
The data is dynamic/calculated, so I can't just say
=AVERAGE(prev,next) since I don't know where missing data will occur in advance - I need a solution which takes this into account.
