Re: PGF Plot

Hi, could you add some data file and/or reference to what you want to archieve? When I hear "contour", I think of some function f(x,y) (= 3 values: x, y, and f(x,y) typically sampled as matrizes) and the task to find all (x,y) which have the same contour level "q = f(x,y)". These...

Re: Pgftables date

Hi, You told it to load columns={date} but there is no such column. I get ! Package pgfplots Error: Sorry, could not retrieve column 'date' from table 'stdgre.dat'. Please check spelling (or introduce name aliases).. A fix is to insert the string "date" as first line into the data file dat...

Re: Hardcoded RGB images?

You say that you have an "array of color pixels, hardcoded in LaTeX"? Without "hardcoded in LaTeX", I'd say you should generate PNG images and use pdflatex as outlined by Johannes_B. But if you really want to hardcode an image in LaTeX, you could make use of pgfplots. An image is...

Re: Problem with Tikz

Hi, the fact that Acrobat Reader displays it correctly indicates a bug in the other viewer(s). Evince, in particular, appears to be buggy sometimes, especially with some shadings (and your shadow is a shading unless I am mistaken). From what I remember, the previewer uses the same code base as evinc...

Re: Position of Axis Scale Factor in Plot

Hi, You can reconfigure the position by means of styles. In your case, the style definition every y tick scale label/.style={ at={(yticklabel* cs:1.03,0cm)}, anchor=near yticklabel }, given inside of the option list for your second axis appears to do what you want it to: P.png This choice resembles ...

Re: Balls as Plot Marks Topic is solved

Hi Enzo , There are two key point here: one is the 'mapped color'; it is always redefined to the actual value of the color map. The second is surprisingly difficult to find; it is the way how the mapped color is consumed. One has to say scatter/use mapped color={ball color=mapped color} . Apparently...

Re: Tikz for matlab plots - randomly fails

Hi Jacql, I am author of pgfplots and have read about your problems. Let me stress that there is no upper limit on the number of plots which can be included into a document. Take a look at the pgfplots manual: ~400 pages containing ~400 plots (at least). And it does not even make use of externalizat...

Re: Surface Plots from Matlab

Hi, if I am not mistaken, there are a couple of different ways to generate an eps export from matlab - and not all of them are good ways. The preferred way would be to plot your surface as usual in matlab, then type "print -depsc <filename>" . I believe that this command accepts a sampling...

Re: Tikz and large automata

Hi DenBeke, The message indicates that some intermediate (?) computation result became unexpectedly huge - perhaps as result of a division by some very small number. I suppose it should be possible to identify the culprit by reducing your huge example to some smaller picture; perhaps there are some ...

Re: Aperiodic Grid Topic is solved

Hi, TikZ offsers the options xstep and ystep when using its grid instruction: \tikz \draw (0,0) grid [xstep=.5,ystep=.75] (3,2); However, your example looks as if you'd like to visualize some (data) plot. You might be interested in the package pgfplots : it is based on tikz (and offers all of tikz's...
