Dismissive and cryptic with basic test data

[forthrin]

for c in head tail; do for l in {1..4}; do for o in '' -B -S -L -V -T -H; do printf "x\ty\n1\t2\n3\t4\n5\t6\n" | $c -$l | incplot $o; done; done; done

The tool shrugs off optimistically explorative beginners with cryptic exception codes.

It also seems partial to header fields, though they would be understood with only two columns.

Would appreciate (in order of preference):

A) More intuitive parsing of input data
B) More helpful output messages
C) At the very least, common pitfall notices in the README that covers the above, and similar

I understand the confusion.

What is happening here:
In effect you are trying to draw all the 6 types of plots with several iterations of sample data each.
However, for most of those combinations incplot determines that the data provided is not particularly suitable and outputs an error (eg. stacked bar chart is not practical without some sort of labels ... and there is no column that looks like labels).

Regarding the error messages themselves: That is an unfortunate omission on my part, because the actual human friendly error explanations seem not getting printed. This will be fixed.

Had issues with complex data too, eg. what is wrong with the following data for most of the plots?

$ for o in '' -B -S -L -V -T -H; do (echo x,y,z; for f in {1..10}; do echo $RANDOM,$RANDOM,$RANDOM; done) | incplot $o; done

Not sure what you have planned, but everyone will be none the wiser if the fix is mostly the exceptions with word spacing.

What would be actually useful is printing the minimum requirements, facts as stderr and sample data as stdout, so you can pipe them straight into incplot again for instant gratification. Could you bless your fans with this behemoth convenience?

$ incplot --graph-o-matic-2000 < data
Graph-o-matic 2000 minimum requirements
Header:  Required
Columns: 3
Rows:    2
a⇥b⇥c
1⇥2⇥3
4⇥5⇥6
$ incplot --graph-o-matic-2000 < data | incplot
# (Insert amazing plot here)

Is it supposed to be able to plot single dimension data, ie. a simple graph? Because it refuses.

$ for o in '' -B -L -S -V -T -H; do printf "1\n2\n" | incplot $o; done
Error encountered.
Error category is: Unexp_parser
Error name is: NDJSON_isNotFlat
