HOW-TO Guide for Roadmapper

Table of contents:



How to display multiple tasks or activities on the same line?

To display tasks on the same line as other tasks, call add_parallel_task() method as shown below.

group = my_roadmap.add_group("Core Features")
task = group.add_task("Feature 1", "2022-12-01", "2023-02-10")
task.add_parallel_task("Feature 2", "2023-03-01", "2023-04-30")

Remember to use task instance returned from add_task() method to invoke add_parallel_task() method. The code example basically shows "Feature 2" on the same parallel line as "Feature 1"

How to display milestone on tasks?

To display a milestone on task. call add_milestone() method.

task = group.add_task("Feature 4", "2023-01-21", "2023-05-30")
task.add_milestone("Milestone 1", "2023-05-31")

Remember to use 'task' instance returned from add_task() method to invoke add_milestone() method. The code example shows a milestone on 31 May 2023 with the label "Milestone 1"

How to show generic dates instead of actual date?

To show generic date such as 'Month 1, Month 2, etc", add show_generic_dates=True to the set_timeline() method parameters.

my_roadmap.set_timeline(
    mode=TimelineMode.MONTHLY, 
    start="2022-11-14", 
    number_of_items=6, 
    show_generic_dates=True
)

How to show current date marker 🔽?

To display the current date marker, add show_marker=True to the Roadmap() constructor parameters.

my_roadmap = Roadmap(4100, 2000, show_marker=True)

See the sample roadmap in the gallery

How to use the built-in colour scheme?

my_roadmap = Roadmap(4100, 2000, colour_theme="ORANGEPEEL")

There are five colour themes added into version 0.2.2:

  • "DEFAULT"
  • "BLUEMOUNTAIN"
  • "GREENTURTLE"
  • "ORANGEPEEL"
  • "GREYWOOF"

See the sample roadmaps in the gallery

How to create and use custom colour scheme?

To create custom colour scheme, first create a .json file with the following content:

{
    "theme": "RAINBOW",
    "settings": {
        "background": {
            "background_fill_colour": "#FFFFFF"
        },
        "title": {
            "title_font": "arial.ttf",
            "title_font_size": 26,
            "title_font_colour": "#000000",
            "subtitle_font": "arial.ttf",
            "subtitle_font_size": 18,
            "subtitle_font_colour": "#000000"
        },
        "timeline": {
            "timeline_year_font": "arial.ttf",
            "timeline_year_font_size": 12,
            "timeline_year_font_colour": "#FFFFFF",
            "timeline_year_fill_colour": "#4C5B5C",
            "timeline_item_font": "arial.ttf",
            "timeline_item_font_size": 12,
            "timeline_item_font_colour": "#FFFFFF",
            "timeline_item_fill_colour": "#4C5B5C"
        },
        "marker": {
            "marker_font": "arial.ttf",
            "marker_font_size": 12,
            "marker_font_colour": "#000000",
            "marker_line_colour": "#000000"
        },
        "group": {
            "group_font": "arial.ttf",
            "group_font_size": 12,
            "group_font_colour": "#FFFFFF",
            "group_fill_colour": "#FCA311"
        },
        "task": {
            "task_font": "arial.ttf",
            "task_font_size": 12,
            "task_font_colour": "#000000",
            "task_fill_colour": "#8FBC94",
            "task_style": "rectangle"
        },
        "milestone": {
            "milestone_font": "arial.ttf",
            "milestone_font_size": 12,
            "milestone_font_colour": "#000000",
            "milestone_fill_colour": "#3D6642"
        },
        "footer": {
            "footer_font": "arial.ttf",
            "footer_font_size": 12,
            "footer_font_colour": "#000000"
        }
    }
}
  • You can change font, font size, font colour, fill colour, and task style.
  • Font colour and fill colour can be in hex format or in web colour name format. For example, "#FFFFFF" or "white".

Second, save the json file and give it a name. For example, "rainbow.json".

And finally, make a reference in your code as below:

my_roadmap = Roadmap(4100, 2000, colour_theme="rainbow.json", colour_theme="rainbow.json")

Make sure your .py file and .json file are in the same folder.

How to add sub title to the roadmap?

To add sub title beneath the main title, just call the set_subtitle() method.

    my_roadmap.set_title("ROADMAP EXAMPLE 2022/2023")
    my_roadmap.set_subtitle("This is a subtitle")

How to let roadmapper auto adjust roadmap height?

To let roadmapper to automatically resize the height, add auto_height=True to the Roadmap constructor parameters.

my roadmap = Roadmap(
        1200,
        1400,
        auto_height=True,
    )

How to add logo to the roadmap?

To add logo, call add_logo() method and specify the display position.

my_roadmap.add_logo("matariki-tech-logo.png", position="top-right", width=50, height=50
  • position can be one of the following values
    • top-left
    • top-centre
    • top-right
    • bottom-left
    • bottom-centre
    • bottom-right
  • width and height are used to resize the logo

How to display non-English characters?

To display non-English characters, follow the steps below:

  1. Download font file that supports unicode especially the one that support your language. For example, to display Traditional Chinese characters, you need to download a font that supports Traditional Chinese characters like this one HanSerifTC Font. Roadmapper uses Pillow library which support both TrueType and OpenType fonts.
  2. Place the font file in your designated folder relative to your .py file.
  3. Create a custom colour scheme .json file, change the font to the font file you downloaded in step 1. For example, if you downloaded the HanSerifTC font, you can change the font to "fonts/SourceHanSerifTC-Regular.otf". In my case, I store my font file in a folder called "fonts" relative to my .py file. The file is saved as traditional-chinese.json in the same folder as my .py file.
{
    "theme": "TRADITIONAL-CHINESE",
    "settings": {
        "background": {
            "background_fill_colour": "#FFFFFF"
        },
        "title": {
            "title_font": "fonts/SourceHanSerifTC-Regular.otf",
            "title_font_size": 26,
            "title_font_colour": "#000000",
            "subtitle_font": "fonts/SourceHanSerifTC-Regular.otf",
            "subtitle_font_size": 18,
            "subtitle_font_colour": "#000000"
        },
        "timeline": {
            "timeline_year_font": "fonts/SourceHanSerifTC-Regular.otf",
            "timeline_year_font_size": 12,
            "timeline_year_font_colour": "#FFFFFF",
            "timeline_year_fill_colour": "#4C5B5C",
            "timeline_item_font": "fonts/SourceHanSerifTC-Regular.otf",
            "timeline_item_font_size": 12,
            "timeline_item_font_colour": "#FFFFFF",
            "timeline_item_fill_colour": "#4C5B5C"
        },
        "marker": {
            "marker_font": "fonts/SourceHanSerifTC-Regular.otf",
            "marker_font_size": 12,
            "marker_font_colour": "#000000",
            "marker_line_colour": "#000000"
        },
        "group": {
            "group_font": "fonts/SourceHanSerifTC-Regular.otf",
            "group_font_size": 12,
            "group_font_colour": "#FFFFFF",
            "group_fill_colour": "#FCA311"
        },
        "task": {
            "task_font": "fonts/SourceHanSerifTC-Regular.otf",
            "task_font_size": 12,
            "task_font_colour": "#000000",
            "task_fill_colour": "#8FBC94",
            "task_style": "rectangle"
        },
        "milestone": {
            "milestone_font": "fonts/SourceHanSerifTC-Regular.otf",
            "milestone_font_size": 12,
            "milestone_font_colour": "#000000",
            "milestone_fill_colour": "#4D8052"
        },
        "footer": {
            "footer_font": "fonts/SourceHanSerifTC-Regular.otf",
            "footer_font_size": 12,
            "footer_font_colour": "#000000"
        }
    }
}
  1. Specify the custom colour scheme in the Roadmap constructor.
roadmap = Roadmap(800, 700, colour_theme="traditional-chinese.json")

How to change the timeline display format?

If you are not happy on text display on the timeline particularly when you have a non-english roadmap. To change timeline text display format, follow the steps below:

  1. Create a timeline locale .json file like this one below. You can change or customise the timeline text that you want to display. For example, if you want to display the year in Chinese, you can change the year text to {0} 年. Just remember to keep the {0} as it is. The following file is saved as zh_TW_timeline_settings.json in the same folder as my .py file.
{
    "locale": "zh_TW",
    "settings": {
        "year": {
            "text": "{0} 年",
            "generic_text": "第{0}年"
        },
        "half_year": {"text": "第{0}個半年"},
        "quarter": {"text": "第{0}季度"},
        "month": {
            "text": "{0}",
            "generic_text": "{0}月"
        },
        "week": {
            "text": "{1}{0}",
            "generic_text": "第{0}周"
        }
    }
}
  1. Please make sure the "locale" value you specified is supported by your machine. To get a list of support locale in your machine, run the following code:
import locale
locale.locale_alias
  1. Specify the timeline locale file in the set_timeline() method.
roadmap.set_timeline(
        TimelineMode.QUARTERLY, "2023-01-01", 4, timeline_locale="zh_TW_timeline_settings.json"
    )
