Jansson Consulting: Plot

Plot

Utility to plot some data. Parameter names to use for scripted plotting, e.g. using curl, in paranthesis.

Select plot type (plottype):

Select plot output format (format):

Data sets to plot (data):

Use data from a file, max 10 MB, on the same JSON format as required for data entered in the textarea (datafile):

If a file was selected, its datasets will be appended to datasets entered in the textarea, if any. In total, at least one dataset is required.

Optional legend keys associated to the datasets (legends):

X-axis

Optional label (xlabel):

Scaling (xscale):

Y-axis

Optional label (ylabel):

Scaling (yscale):

You can also call this utility from the command line. For example, using curl to plot the data "[2,4,6,8,10,12]" entitled "test" as a spectrum with log-2 scale on the x axis, log-10 on the y axis, in SVG format and save it to a file "test.svg":

curl -F "plottype=spectrum" -F "format=svg" -F "data=[[2,4,6,8,10,12]]" -F "legends=[\"test\"]" -F "xlabel=X axis" -F "xscale=log2" -F "yscale=log10" https://jansson.net/apps/plot/ -o "test.svg"

Using two datasets with base e logarithm as x-axis scaling:

curl -F "plottype=spectrum" -F "format=svg" -F "data=[[2,4,6,8,10,12],[[2.2,4],[3.3,5],[4.4,5]]]" -F "legends=[\"test 1\",\"test 2\"]" -F "xlabel=X axis" -F "xscale=ln" -F "yscale=log10" https://jansson.net/apps/plot/ -o "test.svg"

Using two "manual" datasets and one dataset in the file "data.json":

curl -F "plottype=spectrum" -F "format=svg" -F "data=[[2,4,6,8,10,12],[[2.2,4],[3.3,5],[4.4,5]]]" -F "datafile=@data.json" -F "legends=[\"manual 1\",\"manual 2\",\"file\"]" -F "xlabel=X axis" -F "xscale=ln" -F "yscale=log10" https://jansson.net/apps/plot/ -o "test.svg"
