Thanks for letting us know. I have submitted a bug in our internal system for this issue. 

I was able to reproduce this issue in 2017.3, however it appears to be fixed in 2018.0.

Thanks for the report. If you encounter other issues, please feel free to Submit a Change Request.

I would vote for @Rouben Rostamian's answer as well, but I'll just mention that there's also a MathApp in Maple that does exactly this; look up ?MathApps,ConicSections 

 

It's also available on the MapleCloud: https://maple.cloud/#doc=9511437

 

In Maple 2018, the plots:-pareto command has been deprecated and replaced by the new Statistics:-ParetoChart command.

Here's the same example in Maple 2018:

with(Statistics):
data := DataSeries([327, 240, 176, 105, 43, 36, 33, 90, 61, 50, 166], labels = ["Engine 1", "Engine 2", "Engine 3", "Wire 1", "Wire 2", "Wire 3", "Oil", "Coils", "Gear Box", "Steam Line", "Others"]):
ParetoChart(data, size = [800, 400]);

You can also note that the ParetoChart command uses tickmark rotation by default.

@Mikhail Drugov : Maple 2018 has added the ability to rotate both tickmarks in 2D-plots as well as text in the plots:-textplot command using the 'rotation' option. For more details see: https://maplesoft.com/products/maple/new_features/Maple2018/visualization.aspx

1. It is not currently possible to adjust the column widths using the summarize option, though this might make for a nice addition. The DataSummary command uses a similar technique to DocumentTools:-Tabulate, however it doesn't dispatch to that command.

In theory, you can pretty easily recreate a summary table using the Tabulate command. For example:

results := evalf[4]~(Statistics:-DataSummary(Matrix([[3,1130,114694],[4,1527,127368],[3,907,88464],[2,878,96484],[4,995,128007]]))):
DocumentTools:-Tabulate( <map(lhs,results[1]) | map(rhs,results[1]) | map(rhs,results[2]) | map(rhs,results[3])>, weights = [20,25,25,25]):

2. For saving a table to an image, the only thing I can think of is to grab it using a screenshot (see above).

I'll add an internal ticket for the enhancements discussed above.

If you're looking for additional input, MaplePrimes is as good a place as any to start a discussion on modifying or expanding commands. Otherwise, you can send an "official" request to Maplesoft using the SCR form here: https://www.mapleprimes.com/scr/new
