Gnuplot: plotting histograms on Y-axis - matplotlib

Question

I'm trying to plot a histogram for the following data:
<text>,<percentage>
--------------------
"Statement A",50%
"Statement B",20%
"Statement C",30%
I used the set datafile separator "," to obtain the corresponding columns. The plot should have percentage on the X-axis and the statements on the Y-axis (full character string). So each histogram is horizontal.
How can I do this in gnuplot?
Or is there other tools for plotting good vector images?

Answer 1

The gnuplot histogram and boxes plotting styles are for vertical boxes. To get horizontal boxes, you can use boxxyerrorbars.
For the strings as y-labels, I use yticlabels and place the boxes at the y-values 0, 1 and 2 (according to the row in the data file, which is accessed with $0).
I let gnuplot treat the second column as numerical value, which strips the % off. It is added later in the formatting of the xtics:
set datafile separator ','
set format x '%g%%'
set style fill solid
plot 'data.txt' using ($2*0.5):0:($2*0.5):(0.4):yticlabels(1) with boxxyerrorbars t ''
The result with version 4.6.4 is:

#Christoph Thank you. Your answer helped me.
#Slayer Regarding your question to add labels using gnuplot v5.2 patchlevel 6 and using #Christoph's provided sample.
Sample Code:
# set the data file delimiter
set datafile separator ','
# set the x-axiz labels to show percentage
set format x '%g%%'
# set the x-axis min and max range
set xrange [ 0 : 100]
# set the style of the bars
set style fill solid
# set the textbox style with a blue line colour
set style textbox opaque border lc "blue"
# plot the data graph and place the labels on the bars
plot 'plotv.txt' using ($2*0.5):0:($2*0.5):(0.3):yticlabels(1) with boxxyerrorbars t '', \
'' using 2:0:2 with labels center boxed notitle column
Sample Data Provided:(plotv.txt)
<text>,<percentage>
--------------------
"Statement A",50%
"Statement B",20%
"Statement C",30%
