Graphviz: align nodes on left side instead of centering (With answer)

Question

I made a python script to plot a directory structure using graphviz. In order to render the graph correctly, I use rankdir=LR. However, nodes having the same rank are centered.

See the following image.

Graph result

As you can see, nodes like ".gitignore", ".travis.yml", etc don't have the same width because of their label. I would like to have nodes in the same rank aligned on the left side no matter their width.

I have seen other related posts like this one but I don't want to force nodes width.

Is there any other way to do it?

Thanks in advance for your answers and have a nice day.

P.S.: Here's a sample of my graph code:

[EDIT]

After a few researches and thanks to @TomServo, I have been able to "fix" the nodes width.

I use the following code. ImageFont doc can be found here

font = ImageFont.truetype('DejaVuSansMono.ttf', FONT_SIZE)
width = font.getsize("YOUR STRING TO MEASURE HERE")[0]
# convert pixels to inches and add extra space for icons and margins
# icon size is defined as points which is a 72's of an inch
width = width / GRAPHVIZ_DPI + ((1 / 72) * 20 * 2)

Then the result:

Sorry, but I don't think there is a way to achieve the effect you want without fixing the width of the nodes in a rank. You may want to reconsider though because making your nodes the same width really makes the graph much neater:

Notice the width=2.0 at the end of the first few nodes. This makes them the same width and cleans up the ragged look a little.

Also, do put rankdir=LR near the top as shown, and as you mentioned in your question.

To "precompute" the width necessary, on a Windows system I would use the Graphics namespace to determine width, something like this:

private void MeasureStringWidth(PaintEventArgs e)
{

    // Set up string.
    string measureString = "Measure String";
    Font stringFont = new Font("Arial", 16);

    // Set maximum width of string.
    int stringWidth = 200;

    // Measure string.
    SizeF stringSize = new SizeF();
    stringSize = e.Graphics.MeasureString(measureString, stringFont, stringWidth);

    // Draw rectangle representing size of string.
    e.Graphics.DrawRectangle(new Pen(Color.Red, 1), 0.0F, 0.0F, stringSize.Width, stringSize.Height);

    // Draw string to screen.
    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, new PointF(0, 0));
}

Then convert the stringSize.Width value to inches for example. Add a little padding, add a little extra for your included icon graphics and then use that for your uniform width.

Finally, if you're not on a Windows system, or not using .NET, there may be other ways to measure the width of a string, as in the example with python and tkinter. So don't give up, you can do it!

Thank you for your answer. I will fix the node width. Do you know if there is a way to ”precompute” the width of the bigger node in order to apply it to each node? — Maël Pedretti, Feb 24 '18 at 07:45
The Graphviz reference manual gives no clue as to figuring out the largest width, so I don't think it supports it. However, see my edited answer for an additional idea that will work with a little effort. — TomServo, Feb 24 '18 at 12:12
I haven’t seen anything in the manual either, this is why I asked. I will try your way and estimate the width based on the number of char in the name of the longest file and font size. I am using Python so I don’t think this will be an issue. I had already thought doing it that way but I wanted to know if there were easier ways of doing it. Thank you very much for your answer. Have a nice week end. — Maël Pedretti, Feb 24 '18 at 12:12
I have been able to find a way to calculate the width. Thank you very much. — Maël Pedretti, Feb 27 '18 at 12:44

Graphviz: align nodes on left side instead of centering (With answer)
