Hello all,

Another GRAPH question. Yeay!

I've been asked whether we can create a certain type of graph using WebFOCUS. The graph in question contains several lines for different articles based on measurements. Each measurement has an X-value and a resulting measured Y-value with a deviation range.

I need to plot these lines, with an error-bar for the low/high deviation on the measured Y-value. These error-bars are what's bothering me for whether WebFOCUS (7.6!) can do that.

Alternatively, does anyone have any experience sending graph requests off to an external tool, for example gnuplot? We're running into one limitation of the GRAPH engine after another, it's starting to look like an attractive option...

Hi Wep5622,

From our graph expert: I am not aware of a way to accomplish the type graph you are asking for. And to answer the question of how to move graphs to a different graph language you would just table and hold the data to a format the other language can handle.

Cheers,

Kerry

Netherlands, the kind of graf you want is called Box & Whiskers.
I'm in 7.6.8 (antique, i know),
Open the Advanced Graf Assist tool.
It will show you the bar chart types by default.
pick the 1st one in the 2nd row.
they call it 'Error bar'
but it's Box & Whiskers.
You should be fine.

Aha, so they're called "Whiskers" then. Good to know.

Unfortunately, I need those whiskers on a line-graph instead of on a bar-graph.
Additionally, I need several lines with whiskers in a single graph.

It looks like this is impossible with the current graph engine...

Excel can create these graphs, so this is going to be a bit of a hard sell to the user.

Wep5622,

Might not be exactly what you want...
...but perhaps close enough?

-* some fake data
TABLE FILE CAR
	SUM 
		SALES
		COMPUTE LOW/D12 = SALES * AVE.SEATS / 7;
		COMPUTE HIGH/D12 = SALES * AVE.SEATS / 2;
	BY	CAR
ON TABLE HOLD AS TEST
END

-* graphed in adv.graph edit ( cleared out the junk to post it to focalpoint )

setMarkerSize(getSeries(0),75);
setMarkerShape(getSeries(2),2);
setFillColor(getSeries(2),new Color(0,0,0));
ENDSTYLE
END

Good luck

Interesting workaround! It looks like I may be able to use that.

Edit: Just noticed that this is a VLINE type graph, so my X-values will just be in sequence instead of on the correct coordinate.
I think a scatter-graph could be coerced to behave the same though.
