yep, I never thought I would use that formula but in polar case, I need to use. Thanks for the help and information. I have found a different answer also. Here I learned that you can directly use as vectors;
Code:
set terminal png large size 1920,1200
set output '003A98B70A10_coverage.png'
set grid
set origin 1724012,7451336
set isosample 150
set palette defined (-100 "red", -95 "yellow", -85 "green")
plot "003A98B70A10.log" using 1:2:(1724012-$1):(7450200-$2):3 with vectors palette
which is similar to your logic, subtracting the values from the origin.
Hi again. Sorry if it seems like I'm spamming the boards a bit, but I figured I might as well ask all the questions I need answers to at once, and hopefully at least get some.

Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:
for example plot filename.txt
It says that (.txt ) is not identified ... I tried to write it without the .txt part, but I also get the error msg.
Any idea why? :confused: (1 Reply)
Hi I am trying to fit my histogram data with a gaussian model and am encountering two problems:

gpsprof
GPSPROF(1) GPSD Documentation GPSPROF(1)NAME
gpsprof - profile a GPS and gpsd, plotting latency information
SYNOPSIS
gpsprof [-f plot_type] [-m threshold] [-n packetcount] [-t title] [-T terminal] [-d dumpfile] [-l logfile] [-r] [-D debuglevel] [-h]
[[server[:port[:device]]]]
DESCRIPTION
gpsprof performs accuracy and latency profiling on a GPS. It emits to standard output a GNUPLOT program that draws an illustrative graph.
It can also be told to emit the raw profile data. The information it provides can be useful for establishing an upper bound on latency, and
thus on position accuracy of a GPS in motion.
gpsprof uses instrumentation built into gpsd.
To display the graph, use gnuplot(1). Thus, for example, to display the default spatial scatter plot, do this:
gpsprof | gnuplot -persist
To generate an image file:
gpsprof -T png | gnuplot >image.png
OPTIONS
The -f option sets the plot type. The X axis is samples (sentences with timestamps). The Y axis is normally latency in seconds. Currently
the following plot types are defined:
space
Generate a scattergram of fixes and plot a probable-error circle. This data is only meaningful if the GPS is held stationary while
gpsprof is running. This is the default.
uninstrumented
Plot total latency without instrumentation. Useful mainly as a check that the instrumentation is not producing significant distortion.
It only plots times for reports that contain fixes; staircase-like artifacts in the plot are created when elapsed time from reports
without fixes is lumped in.
instrumented
Plot instrumented profile. Plots various components of the total latency between the GPS's fix time fix and when the client receives
the fix.
For purposes of the description, below, start-of-reporting-cycle (SORC) is when a device's reporting cycle begins. This time is detected by
watching to see when data availability follows a long enough amount of quiet time that we can be sure we've seen the gap at the end of the
sensor's previous report-transmission cycle. Detecting this gap requires a device running at 9600bps or faster.
Similarly, EORC is end-of-reporting-cycle; when the daemon has seen the last sentence it needs in the reporting cycle and ready to ship a
fix to the client.
The components of the instrumented plot are as follows:
Fix latency
Delta between GPS time and SORC.
RS232 time
RS232 transmission time for data shipped during the cycle (computed from character volume and baud rate).
Analysis time
EORC, minus SORC, minus RS232 time. The amount of real time the daemon spent on computation rather than I/O.
Reception time
Shipping time from the daemon to when it was received by gpsprof.
Because of RS232 buffering effects, the profiler sometimes generates reports of ridiculously high latencies right at the beginning of a
session. The -m option lets you set a latency threshold, in multiples of the cycle time, above which reports are discarded.
The -n option sets the number of packets to sample. The default is 100.
The -t option sets a text string to be included in the plot title.
The -T option generates a terminal type setting into the gnuplot code. Typical usage is "-T png" telling gnuplot to write a PNG file.
Without this option gnuplot will call its X11 display code.
The -d option dumps the plot data, without attached gnuplot code, to a specified file for post-analysis.
The -l option dumps the raw JSON reports collected from the device to a specified file.
The -r option replots from a JSON logfile (such as -l produces) on standard input. Both -n and -l options are ignored when this one is
selected.
The -h option makes gpsprof print a usage message and exit.
The -D sets debug level.
Sending SIGUSR1 to a running instance causes it to write a completion message to standard error and resume processing. The first number in
the startup message is the process ID to signal.
