I have seen this question before but not any answers.
I need to generate plots of data where the X axis is always date/time.
These plot image files will be included in web pages via img tags.
I also need to make the resulting web image "clickable" via an image map so
that viewers can see the original data values.
How can one generate the relevant HTML image maps (or some form of text file
with identifiable coordinate pairs) with gnuplot?
(I currently do this with grace plots by replicating the PNG plots with the
Metadata output option and feeding the results plus the original data file
through a gawk script.)
TIA,
Stephen Davies

after plotting a whole bunch of variables is set, see 'show variables all'. amongst these variables there are GPVAL_TERM_XMIN, GPVAL_TERM_XMAX, GPVAL_TERM_YMIN, GPVAL_TERM_YMAX which give the corners of the graph in pixels. (you need version 4.4) together with the information in GPVAL_X_MIN, GPVAL_X_MAX, ... it should be easy to translate data point coordinates into pixels. you should generate your plot, then replot with 'set table <filename>' the resulting file should contain all of your data points in graph coordinates which with the above variables you may convert into terminal screen coordinates. scldad wrote: > > I have seen this question before but not any answers. > > I need to generate plots of data where the X axis is always date/time. > > These plot image files will be included in web pages via img tags. > > I also need to make the resulting web image "clickable" via an image map > so > that viewers can see the original data values. > > How can one generate the relevant HTML image maps (or some form of text > file > with identifiable coordinate pairs) with gnuplot? > > (I currently do this with grace plots by replicating the PNG plots with > the > Metadata output option and feeding the results plus the original data file > through a gawk script.) > > TIA, > Stephen Davies > -- > ============================================================================= > Stephen Davies Consulting P/L Voice: 08-8177 > 1595 > Adelaide, South Australia.

Thank you Thomas. This looks very promising. The initial plot image is good. However, when I do the replot with a table set, the X coordinates (date/time) do not seem to follow the rules in the doco. I did: set table "/tmp/pdata" set xdata time set timefmt "%Y-%m-%d_%H:%M:%S" set format x "%s" plot "/tmp/data" using 1:2 with lines unset table /tmp/pdata contains lines of the format: "" 5.489 i If I omit the set format x, I get lines of the format: "g" 5.489 i How do I get the date/time x values output as seconds? (GPVAL_X_MIN value implies that these are the units plotted.)

"%s" is not implemented - but it should be implemented. i uploaded a patch to sourceforge which repairs this. scldad wrote: > > Thank you Thomas. > > This looks very promising. > > The initial plot image is good. > > However, when I do the replot with a table set, the X coordinates > (date/time) > do not seem to follow the rules in the doco. > > I did: > > set table "/tmp/pdata" > set xdata time > set timefmt "%Y-%m-%d_%H:%M:%S" > set format x "%s" > plot "/tmp/data" using 1:2 with lines > unset table > > /tmp/pdata contains lines of the format: > > "" 5.489 i > > If I omit the set format x, I get lines of the format: > > "g" 5.489 i > > How do I get the date/time x values output as seconds? > (GPVAL_X_MIN value implies that these are the units plotted.) > > Cheers and thanks, > Stephen > On Wednesday 09 December 2009 19:04:55 Thomas Sefzick wrote: >> after plotting a whole bunch of variables is set, see 'show variables >> all'. >> amongst these variables there are >> GPVAL_TERM_XMIN, GPVAL_TERM_XMAX, >> GPVAL_TERM_YMIN, GPVAL_TERM_YMAX >> which give the corners of the graph in pixels. >> (you need version 4.4) >> >> together with the information in >> GPVAL_X_MIN, GPVAL_X_MAX, ... >> it should be easy to translate data point coordinates into >> pixels. >> >> you should generate your plot, then replot with 'set table <filename>' >> the resulting file should contain all of your data points in graph >> coordinates which with the above variables you may convert into >> terminal screen coordinates. >> >> scldad wrote: >> > I have seen this question before but not any answers. >> > >> > I need to generate plots of data where the X axis is always date/time. >> > >> > These plot image files will be included in web pages via img tags. >> > >> > I also need to make the resulting web image "clickable" via an image >> map >> > so >> > that viewers can see the original data values. >> > >> > How can one generate the relevant HTML image maps (or some form of text >> > file >> > with identifiable coordinate pairs) with gnuplot? >> > >> > (I currently do this with grace plots by replicating the PNG plots with >> > the >> > Metadata output option and feeding the results plus the original data >> > file through a gawk script.) >> > >> > TIA, >> > Stephen Davies >> > -- >> > >> ========================================================================= >> >==== Stephen Davies Consulting P/L Voice: >> > 08-8177 1595 >> > Adelaide, South Australia.
