plplot-general Mailing List for PLplot

Hi Anan, Thank you very much for your quick response, and for the detailed information you kindly sent me. After reading through PLplot document I realized that my first email was not very clear and might have confused you. Let me show my code first: ######################################### # CODE STARTS FROM HERE (FORTRAN) ######################################### subroutine plplot_contour(lclab,ccol,clskip,clspace,cthick,shedge,xg,yg,zg) implicit none logical , intent(in) :: lclab integer(4) , intent(in) :: ccol, clskip real(8) , intent(in) :: clspace real(8) , intent(in) :: cthick real(8) , intent(in) :: shedge(:) real(8) , intent(in) :: xg(:), yg(:), zg(:,:) ! work integer(4) :: nxc, nyc integer(4) :: i, nshedge, sigdig nxc = size(zg,1) nyc = size(zg,2) nshedge = size(shedge) call plcol0(ccol) call plwidth(cthick) do i=1, nshedge if( shedge(i)>=0 )then ! solid line call pllsty(1) else ! broken line call pllsty(2) endif if( lclab .and. mod(i-1,clskip)==1 )then ! with label call pl_setcontlabelparam( 0.01D0, 0.6D0, clspace, 1) else ! without label call pl_setcontlabelparam( 0.01D0, 0.6D0, clspace, 0) endif sigdig = numsigdig( shedge(i) ) call pl_setcontlabelformat(4,sigdig) call plcont( zg , 1, nxc, 1, nyc, & & (/shedge(i)/), xg, yg ) enddo end subroutine plplot_contour ############################################################ # CODE ENDS HERE (Many thanks again for supporting FORTRAN!) ############################################################ This is a FORTRAN code which takes a 2-dimentional array and plot it with plcont, where I also use pl_setccontlabelparam to specify how far contour labels stand "off lines". In this specific case, I suppose that the best example would be Demo09-01: http://plplot.org/examples.php?demo=09 , , and I tried to ask if countour labels could be placed in line-break, e,g, : https://docs.generic-mapping-tools.org/6.3/gallery/ex13.html.

Hi Shozee: I am answering you on the assumption your subject line should have been "line break for PLplot" since you did not mention plcont anywhere inside your email. If that assumption is correct I suggest you take a look at pllegend which was designed to give users tremendous control over how text (and graphics) are arranged within a legend (within a plot). Of course, that enormous capability makes its API complex, but check the [documentation of that API](http://plplot.org/docbook-manual/plplot-html-5.15.0/pllegend.html) to see whether that API might provide exactly what you need. That API is demonstrated in a simplistic way in [example 4](http://plplot.org/examples.php?demo=04) and [example 26](http://plplot.org/examples.php?demo=26) which are useful to show how to turn everything off other than the small subset of that API that you need. That API is demonstrated in a more comprehensive way in [example 33](http://plplot.org/examples.php?demo=33). Good luck and let us know how it goes! Alan __________________________ Alan W.

I am currently developing an interactive plotter that does some number-crunching and shows results with plplot. First of all, I thank all the developers for making this beautiful software available to us. The simple APIs with the perfect document let my small project quickly shape up. There is one option I wish I could have in plplot: making a linebreak to put labels in between. To be precise, there may be two options. One is, make a line, put a white box on the line, then put numbers in. The other option is, literally break a line (draw two lines with some space) and put numbers in between. (Both look good to me). Hopefully anyone can spare some time to consider adding it or tell me how ? Shozee
