Y label gets clipped

[rahulporuri]

Problem Description

The Y label in the following example doesn't get displayed while the X label gets displayed.

Reproduction Steps:

from numpy import linspace, sin
from traits.api import HasTraits, Instance
from traitsui.api import View, Item
from chaco.api import Plot, ArrayPlotData
from enable.api import ComponentEditor

class LinePlot(HasTraits):
    plot = Instance(Plot)

    traits_view = View(
        Item('plot',editor=ComponentEditor(), show_label=False),
        width=500, height=500, resizable=True, title="Chaco Plot")

    def _plot_default(self):
        x = linspace(-14, 14, 100)
        y = sin(x) * x**3
        plotdata = ArrayPlotData(x=x, y=y)

        plot = Plot(plotdata)
        plot.plot(("x", "y"), type="line", color="blue")
        plot.title = "sin(x) * x^3"

        plot.x_axis.title = "X AXIS"
        plot.y_axis.title = "Y AXIS"

        return plot

if __name__ == "__main__":
    LinePlot().configure_traits()

Expected behavior:

We expect the Y label to be displayed.

OS, Python version: Windows 10 Pro. Python 3.6.0. Chaco 4.8.0. Enable 4.8.1.

Note that the title is actually there, but the default padding is such that most of the text is clipped. This requires overriding the plot.padding_left attribute to create enough space to show the text.

This is not a bug per-se as @timdiller points out - but what might help with these problems is to perhaps adjust the default values of the right and left padding based on the presence or absence of a non-empty axis title.

Or alternatively, use the edge of the padding as the guide for the location of the axis title?
