First of all, I would just like to point out I have next to nothing knowledge about data representation, so I would be more then thankful if someone could answer this question on as basic level as it could be.

I have three different data sets which I need to plot on the very same graph. The first data set is calculated for each year (each graph represents one year) and its purpuse is to show borders between data (e.g. below that value discard all data, between this and this value use weight X, etc). The other data sets represent non-cloudy days wihtin the year and the third set of data are actual values measured every hour for the observed day (14 hours per day).

As you can see, in theory, for one year I could have no data at all (all days in the year are cloudy) and for the next year I could have 365 days with each of them carrying 14 different values.

Plain and simple, are there any known graphs for as simple as possible representing this kind of data?

To explain a little bit I'm pasting one homemade graph for this problem. However, I fear that this kind of graph could turn to be pretty messy if there are lots of sunny days in the year.

P.S. Attached dummy .csv. In the first column are values for given year (in the picture red line); in the second column are dates (black lines) for a gives year; in the rest of columns are values for a particular day in a year (blue curve).

I am going to use R. I used `dput`

after reading in the data to make all this reproducible. Define the data and the levels:

`example <- structure(list( V1 = structure(c(4L, 7L, 8L, 3L, 6L, 10L, 11L, 1L, 5L, 12L, 2L, 9L), .Label = c("12.7.", "14.11.", "14.4.", "15.1.", "15.10.", "15.5.", "17.2.", "18.3.", "22.12.", "22.6.", "24.6.", "27.10."), class = "factor"), V2 = c(NA, NA, NA, 7L, 42L, 57L, 41L, 17L, NA, NA, NA, NA), V3 = c(NA, NA, 22L, 71L, 135L, 175L, 139L, 103L, 29L, NA, NA, NA), V4 = c(NA, 43L, 109L, 175L, 244L, 256L, 299L, 240L, 152L, 77L, 22L, NA), V5 = c(95L, 165L, 245L, 300L, 374L, 375L, 400L, 375L, 299L, 200L, 95L, 45L), V6 = c(180L, 252L, 334L, 421L, 470L, 400L, 529L, 555L, 440L, 330L, 175L, 125L), V7 = c(237L, 325L, 495L, 500L, 540L, 535L, 626L, 616L, 557L, 440L, 225L, 189L), V8 = c(257L, 356L, 450L, 575L, 600L, 602L, 650L, 663L, 616L, 475L, 303L, 199L), V9 = c(245L, 355L, 455L, 550L, 597L, 602L, 657L, 678L, 643L, 499L, 357L, 232L), V10 = c(259L, 401L, 500L, 521L, 576L, 575L, 655L, 645L, 375L, 400L, 295L, 218L), V11 = c(222L, 295L, 375L, 495L, 527L, 579L, 599L, 585L, 518L, 400L, 245L, 175L), V12 = c(157L, 230L, 313L, 398L, 415L, 425L, 517L, 481L, 400L, 310L, 166L, 120L), V13 = c(67L, 121L, 195L, 255L, 299L, 305L, 382L, 332L, 275L, 99L, 65L, 21L), V14 = c(NA, NA, 89L, 109L, 208L, 265L, 225L, 201L, 118L, 43L, NA, NA), V15 = c(NA, NA, NA, 48L, 108L, 121L, 118L, 70L, 12L, NA, NA, NA), V16 = c(NA, NA, NA, NA, 22L, 39L, 21L, NA, NA, NA, NA, NA)), .Names = c("V1", "V2", "V3", "V4", "V5", "V6", "V7", "V8", "V9", "V10", "V11", "V12", "V13", "V14", "V15", "V16"), class = "data.frame", row.names = c(NA, -12L)) example.levels <- c(115,170,250,330,385,600) `

Then we plot twelve subplots. In each subplot, we add your levels as horizontal lines. Note that I am constraining the $y$ axis to be identical across plots so we can visually compare them:

`opar <- par(mfrow=c(3,4),mai=c(.2,.3,.3,.1)+.02) for ( ii in 1:12 ) { plot(1:15,as.numeric(example[ii,-1]),xlab="",ylab="", xaxt="n",main=example[ii,1],ylim=c(0,700),type="o") abline(h=example.levels,col="grey") } par(opar) `

I am not putting the times on the x axis since they will be hard to read anyway, but perhaps one could truncate the minutes and just note the hours. Result:
