[Plplot-general] Fwd: x Axis in Date Format has wrong ticks

[Marc R. <mar...@gm...>]

Hi !

Sorry for double posting. I already posted this to the project tracker
support requests. However that's 1 week ago and I noticed that almost no
support request there got a reply. So I'm posting it here again. I hope
that's ok.

I'm logging temperature values and would like to plot them with a graph.
I temperature values are not captured in equal timely distances.

If I use this:

plbox("bcnstd", 0, 0, "bcnstv", 5, 5);

I get graphok.svg

Since I want to have more ticks on the x axis and would prefer them in 6
hour steps instead of 10, I tried this

plbox("bcnstd", 60 * 60 * 6, 6, "bcnstv", 5, 5);

which results in graphbugged.svg.

Am I doing something wrong or is this a bug?

Best regards
   Marc


Here is the rest of my code

plsdev("svg");
plsetopt("o", "temp\\a.svg");
plsetopt("geometry", "1024x512");
plinit();

plfont(1);
plschr(0, 0.5);
pltimefmt("%d %H-%M-%S");

plenv(x.GetFront(), x.GetBack(), 0, 50, 0, 40);
plbox("bcnstd", 60 * 60 * 6, 6, "bcnstv", 5, 5);
pllab("", "Temperature", "");
plcol0(1);
plline(x.GetN(), x.GetPointer(), y.GetPointer());

plend();
