When making a simple barchart for speedup, I'd like to have a horizontal
line at y=1. I can hack this with:

extraops=plot 1,3

but that relies on knowing that the y-range is 3. If I instead try

extraops=plot 1

the graph is ruined.

Could an option for this be added (or is there another workaround)?

Thanks

It will be good if bargraph.pl could generate combination of cluster, multibar, and multidata.

What is the expected output? What do you see instead?
I attached the output example file.

Hi,
I have tested the latest release version and version 4.7. The file generated by bargraph is mal-formed
and have some extra newlines leading from line 176 for compiling stacked_var.perf.

After removing those redundant newlines, it works properly. So maybe it is a bug that.
I use the following command to generate desired temporary file (stacked_var.dat) for
checking where that bug occurs.

bargraph stacked_var.perf > stacked_var.dat

I use Ubuntu 16.4 with gnu 5.0.7.

From [email protected] on January 17, 2010 11:12:20

in either a plain stacked bargraph, or a cluster of stacked, several people
have requested an option to specify different color schemes for individual
stacked bars. presumably the legend would list all colors.

Hi Derek,

Great script!
I am using the cluster-of-stacked-bars graph for a project of mine.
My problem is that the equivalent labels of
"Private Caches, Shared Caches, Persistent Caches"
in my graph are longer than the bars and so run into each other.
Is it possible to get a rotate variable added for these labels?

Thanks,
Kevin

today the legend's position is either centered at the top or manually
placed, which is cumbersome. from the fig output the script should be able
to support automatic placement, especially w/ the more accurate legend
bounding box calculations in r41 . it could support keywords like
"upper_right" or "far_right" or something.

This seems to be because @fillstyle is not populated beyond element 11. The relevant code is below, I think the if ($custom_colors) section should also be setting $fillstyle[$i] to 20.

Hello,
i have been playing with some examples and found that bars (in the second group) are not filled for example clustered_stack.

Regards,
Yam

I already fixed an issue with gnuplot 5.0 due to its change from linetype to dashtype in 210e259.

Another issue remains: group labels, such as with clustered stacked graphs, are placed at the top of the figure. Looking at the cluster_stacked.perf test and sample, focusing on this label in the gnuplot:

set label "Private Caches" at 0.672000,0 center rotate by 0

With gnuplot 4.4.2 this becomes this line in the fig output:

4 1 -1 0 -1 -1 10 0.000 4 125 1050 2936 4774 Private Caches\001

With 5.0.x it has a 0 value for y:

4 1 -1 0 -1 -1 10 0.000 4 125 1050 2936 0 Private Caches\001

Investigations so far indicate a bug in gnuplot but the final culprit is not yet identified.

From [email protected] on January 17, 2010 11:56:15

Logarithmic axes are not fully supported. For now you can get them to work
with extra options to set the minimum, as well as to use a relative
boxwidth since gnuplot 4.2 no longer narrows the boxes as x increases:

extraops=set logscale
extraops=set xrange [1:28]
extraops=set yrange [1:]
\# in gnuplot 4.2, boxwidth does not shrink, so we don't want the default
\# of 0.5 absolute:
extraops=set boxwidth 0.5 relative

I have a label on my plot that is obscured by some of the bars. I wish to put a white rectangle behind the label in order to make it visible. However, when I attempt to add such a rectangle by doing e.g.:

extraops=set object 1001 rect from graph 0.0, graph 0.0 to graph 1.0, graph 1.0 back fc rgb "white" fs solid noborder

(where I've deliberately made the rectangle large for testing purposes) then I get an error:

Hi, I wonder whether the plotting tool support min-max bars which is similar to the error bar. The difference is that, error bars typically show the mean values and the variance, but the min-max bars should show the mean values and its distance to the min and max values. I wonder how to extend the tool to support the min-max bar?

Thanks for releasing the software, it is very very useful

Using example at http://www.burningcutlery.com/derek/bargraph/cluster.perf fig2dev output produces a lot of "Cannot locate user color X, using default
color on line Y", for high values of X like 92 etc.

Inspecting the fig file reveals that the last bar in every cluster is
assigned a bogus color index X; changing it by hand to correct index
results in proper output

From paul.biggar on September 26, 2009 09:26:08

Using the attached plot, the labels (added with "extraops" commands) are
not the same font size as the legend. I've tried playing with the font for
the extraops (something like adding "Times,7"), but that didn't affect the
font size of the label at all.

There is still a possibility that I'm using this wrong. In this case, it
would be great if the manual could be improved to discuss the interaction
of gnuplot and bargraph's font supports.

Nearly all the bugs and breakage over time have involved gnuplot changing
how it does things or with gnuplot bugs. Maybe we could directly generate
FIG and avoid relying on gnuplot at all? The hard part is computing text
bounding boxes for placement of labels. In the past I looked into using
XTextExtents from perl X11::Lib or X11::Protocol but had trouble with
both.

It seems that the text bounds computed by gnuplot are ignoring capital
letters. I have no idea where the exact problem is, but using capital
letters anywhere shows the bug: put a long strings of caps as an x label,
or any label. For now I've added a hack to try and fudge the bounding box
for the legend but there's no clean way to do it w/o querying X.

What steps will reproduce the problem?
1.Plot a graph such that the y axis maximum is much less than 1

e.g make a graph file:

=cluster Ctl NonCtl
title=test
=table
gene1 0.01 0.01
gene2 0.03 0.03
yformat=%g

2../bargraph.pl -png -non-transparent /tmp/graph.txt > /tmp/graph.png

What is the expected output? What do you see instead?
I expect to see a png containing just the graph and legend. Instead I see the dummy text at the top of the png (BARGRAPH_TEMP_XXX) and lots of empty space between it and a small graph at the bottom of the png.

What version of the product are you using? On what operating system?
Bargraph 4.7 on Centos 6.5

Please provide any additional information below.
It looks like the very small y axis max somehow results in gnuplot emitting fig lines like:
4 0 0 0 -1 0 10.000 0.000 4 125.000 1650.000 6500 -88088 BARGRAPH_TEMP_Ctl\001

The regular expression used to remove this from the fig output only looks for digits at the position occupied by -88088, so the '-' sign prevents the regular expression from matching. I'm not sure if this -ve value is correct, if so then I guess the regexp has to be changed to match this.
