# Drawing graph with two data lines and error range

I am new to LaTeX. How can I draw a graph for this data...

files   1  5.350    ±0.011 ns/op
files 250  218.984  ±0.290 ns/op
files 500  545.244  ±3.784 ns/op
files 750  822.573  ±6.720 ns/op
files 1000 1192.118 ±2.157 ns/op

scanner   1  5.290 ±0.010 ns/op
scanner 250  263.696 ±0.818 ns/op
scanner 500  595.838 ±1.886 ns/op
scanner 750  961.677 ±2.784 ns/op
scanner 1000 1387.766 ±113.272 ns/op


So I want both files and scanner to be on the same graph and for both the error ranges show up as well. y-axis would be time taken. x-axis would be 1, 250, 500, 750, 1000. So basically the graph has two lines - one for scanner, one for files. And each plot should be a dot and also show error range in the same graph like Plotting standard error. I would also like with a line graph for a bar chart like pgfplots: Bar graph with confidence intervals (error)

Welcome! This is to give you a start. I had to remove the ± signs from the data. The errors seem to be overall very tiny.

• @levivah940 A % indicates a comment, i.e. everything after % in a given line won't be "compiled". Very often it is also used to suppress spurious spaces. In the above code, it is unimportant. I was considering adding some comment but then let it be but did not remove the %. However, the % does certainly not hurt here either.
• @levivah940 In order to make these bar charts, just add ybar,, e.g. after xtick=data,. You can then also specify fill colors, e.g. \addplot[color=blue,fill=blue!60,error bars/.cd,y dir=both,y explicit] table[x index=1,y index=2,y error index=3] \datasetA;.
