ENH: Add Curve/PV Settings Modal

[zdomke]

CurveSettingsModal

Create a settings modal for controlling the look of individual curves. The modal will open to the bottom right of its parent widget, similar to the modal in #137.

The modal class, CurveSettingsModal, takes in 3 arguments:

• parent: QWidget
  • This is the parent object of the modal. Should be whatever button opens the modal
• plot: PyDMArchiverTimePlot
  • This is the main plot of Trace
  • This is only used for redrawing the plot when the orientation changes. This should probably be done in PyDM instead of here
• curve: TimePlotCurveItem
  • The curve item that is controlled by the modal

The modal contains settings for:

• Setting the curve's name (label in the legend)
• Color
• Appearance
  • Line type (step or direct)
  • Style (solid, dotted, dashed, etc.)
  • Width
• Symbol
  • Shape (circle, star, none, etc.)
  • Size

Settings components:

Also created a file containing reused components of the settings modals. Changed PlotSettingsModal to use common settings components.

To test this I created test curves and axes at the end of TraceDisplay.__init__(). Here's the code I used:

  self.plot.addAxis(plot_data_item=None, name="Y-Axis 1", orientation="left")
  self.plot.addYChannel(
      y_channel="KLYS:LI22:31:KVAC", name="testing", color="blue", useArchiveData=True, yAxisName="Y-Axis 1"
  )
  self.plot.addAxis(plot_data_item=None, name="Y-Axis 2", orientation="left")
  self.plot.addYChannel(
      y_channel="KLYS:LI22:41:KVAC", name="testing 2", color="green", useArchiveData=True, yAxisName="Y-Axis 2"
  )
  test_button = QPushButton("Test", self)
  self.curve_settings = CurveSettingsModal(test_button, self.plot, self.plot._curves[0])
  test_button.clicked.connect(self.curve_settings.show)
  self.layout().addWidget(test_button)
