using plotille for a real time chart about plotille HOT 4 OPEN

btw, I managed to workaround that with:

self.fig_mem._plots.clear()
self.fig_cpu._plots.clear()

but the color of the lines change every iteration

from plotille.

I also changed to X axis to datetime.datetime.now(), and it seems it is working .. I will investiate a bit more about that.

from plotille.

I created a copy of _color_seq with tee in order to handle keep the same color always.

but if there is a better way to handle that .. I will appreciate a better approach.
thanks!

Hi @xmnlab ,

Thank you for the kind words!

Here is an example for custom ticks: https://github.com/tammoippen/plotille/blob/master/examples/custom_ticks_example.py

The function signature is def default_tick(min_, max_): where min_ and max_ both have the type of the x- or y-axis data (e.g. datetime). They are the minimum and maximum value of the current tick. The return value will be rendered as the tick value - if there is a formatter for the value, it will be formatted. If the return value is a str, the string will be rendered.

Here are tests that use datetime on the x-axis: https://github.com/tammoippen/plotille/blob/master/tests/test_figure.py#L494-L572

When you want time on the x-axis, you have to use date, datetime or numpy.datetime, or write your own converter / formatter. See here for the default converters / formatters of date(time)s. The delta is the difference between the smallest and largest x-value, hence the formatting can be 'refined' depending on how large the difference is (you only have a certain amount of characters per tick to write the tick-value).

Regarding colors, you can either:

• create a new figure every time - the color order for the plots is the same.

• set the color explicitly:

  self.fig_mem.plot(
          container_stats['times'],
          container_stats['mem_usages'],
          label=name,
          lc="red",  # <===
  )

The parameter lc means line color and can be either color names, color codes or rgb values.

Please read this docstring for the color formatting in the terminal. To change the color mode of a figure, use this getter/setter. BTW, you can also set a background color: https://github.com/tammoippen/plotille/blob/master/plotille/_figure.py#L472 .

I hop, this helps you. I am looking forward to see how suger evolves :D.

Best, Tammo
