Hello,

I'm having trouble adjusting labella/nodeHeight and latex/fontsize options.

Example:

• If I set nodeHeight to say, 80, nothing happens to the resulting .pdf or .svg
• If I set fontSize to say, 18, nothing happens to the resulting .pdf or .svg either

Options:

options = {
        "margin": {"left": 70, "right": 20, "top": 20, "bottom": 20},
        "initialWidth": 1300,
        "initialHeight": 1600,
        "direction": "right",
        "dotColor": "#000000",
        "labelBgColor": "#000000",
        "linkColor": "#000000",
        "textFn": lambda x: str(x["time"].date()) + " - " + x["text"],
        "labelPadding": {"left": 2, "right": 0, "top": 2, "bottom": 0},
        "labella": {
            "nodeHeight": 30,
        },
        "latex": {"fontsize": "15pt", "reproducible": True},
    }

Do you have any ideas for how to control these options?

Just found this package - must say it makes life easier!

For the LaTeX output, are the precompuation of the widths really required?
i.e couldn't

\begin{scope}[shift={(40, 3)}]
\fill[color=labelBgColorA, rounded corners=2pt]
(0, 0) rectangle (489, 16.65201) node[midway, yshift=-.75bp, anchor=center, 
           text=labelTextColorA] {\strut \textA};
\end{scope}

be simplified to:

\begin{scope}[shift={(40, 3)}]
\node[rectangle,text centered,anchor=north west,
           rounded corners=2pt,fill=labelBgColorA,yshift=-.75bp] at (0,0) {\strut \textA};
\end{scope}

This would let TikZ figure out the width of the label, rather than having to compute it

Dear @GjjvdBurg,

Thank you for your work. I see your timeline and do you have a horizontal timeline with up and down features. I mean that we can write on both sides. At this moment, I checked your examples files in which we can only write on up or down sides.

Hello,

I'm new to Python. Really excited to use your module, but I seem to be stuck.. Hoping you can help.

Error:

FileNotFoundError: [WinError 2] The system cannot find the file specified

Steps to reproduce:

1. Create a Python virtual env in a new folder: python -m venv .venv
2. Activate venv: .\.venv\Scripts\activate
3. pip install labella, success
4. Copy your example timeline_kit_1.py, paste in a new file in folder timeline.py
5. Execute example: python .\timeline.py

Results in the above error.

Preliminary search:

• Indicates that a filename could be incorrect(?)
• It seems that the tl = TimelineSVG(items, options=options) line causes the problem. If I comment it out, the script executes (though of course, no output).

Hello!

Starting to get acquainted with the tool. Its nice! Thank you.

• Where should I add hyperlinks for timeline events?
  • I tried adding them to the items array, like this, but no-go:

items = [
    {
         "time": date(1986, 1, 1), 
         "text": "\\href{http://www.overleaf.com}{Something Linky}"
     },
     {
         "time": date(1991, 1, 1),
         "text": "\\href{http://www.overleaf.com}{Something Linky}",
    }
]

• Also tried adding it under options to the textfn lambda. But that didn't work.
• Ideally I need the href to be usable in the PDF output
• Please give an example using timeline_kit_1.py if possible.

Using the following borderColor setting inside the options doct did not have any visible effect:

"labelBgColor":  "#fff",
"borderColor": "#000",
"labelTextColor": "#000",

This displayed black text on white background without any border for me. Is that expected?

Dear all,

I just tried to run the examples from https://github.com/GjjvdBurg/labella.py/blob/master/examples/timeline_kit_1.py
I installed within conda enviorement the latexmk, I tested with:

from labella.tex import text_dimensions
text_dimensions("foo", silent=False)

This is the same error as [(https://github.com//issues/14)]

Does anyone have the same issue?
Stay safe and best regards,

Hello, great library. Thanks for developing it!

I'm trying to get a timeline and in VSC and Jupyter Lab I get the "[WinError 2] The system cannot find the file specified", I used pip install and the library loads just fine with example code, it just won't output anything because of that error. What do I need to have installed to run this? specially the tl = TimelineTex(items, options=options) line.

Must be a noob question, but I thought I'd ask. Thanks again!

Hello,

I'm trying to convert the .svg generated by one of the examples to .png.

Tried appending THIS CODE to the main() function below:

#Reference: https://stackoverflow.com/a/70357769/5976033

        {
            "time": date(1991, 1, 1),
            "text": "Goonies",
        },
        {
            "time": date(2021, 4, 1),
            "text": "Matrix",
        }
    ]

        },
        "latex": {"fontsize": "12pt", "reproducible": True},
    }

    tl = TimelineSVG(items, options=options)
    tl.export("timeline_kit_1.svg")

    tl = TimelineTex(items, options=options)
    tl.export("timeline_kit_1.tex")

• But some kind of LaTeX remnant (from textFn?) is present on all timeline events in the resulting .png:

    • The remnants shown below are only present in the reulting .png, not the .pdf/.svg/.tex

Hey there, never used laTex before, but I've installed it with homebrew on OS X. Running Python 3.6

Getting this error:

FileNotFoundError: [Errno 2] No such file or directory: 'latexmk': 'latexmk'

when trying to run the examples provided.

Hi, I had start testing your library with your examples, particularly the example 4, and everything is fine, but when I want to test my own dates it gives me the next error:

Traceback (most recent call last):

I don't know what is wrong, it only happens when I change the date of the example data. Can you please help me to solve it? Thank you!
I'm using Windows 10 x64 with Python 3.6.4 x32, also I tested with python 3.6.3 x64 but the error is still there.

Had a look through the examples but could find one which showed how to adjust the font properties.

On the d3kit-timeline side they use a key as part of the options dict called textStyle:

textStyle: {
    'fill': '#fff',
    'text-decoration' : function(d){ return d.team==='BRA'? 'none': 'underline'},
    'font-weight': function(d){ return d.team==='BRA'? 700: 400}
  }

Tried following that structure with the below but didn't make any difference:

"textStyle": {
    "fill": "#000",
    "text-decoration": "underline",
    "font-weight": 700,
}

Is there maybe an example thay you could include in the examples directory that shows how to use this? Would be interested in changing the font as well.

Is there any way to make something like this picture (events that are more than just a point) but with these nice labels?
