Member Enumeration Documentation

◆ MenuOptions

There is a menu option for everything in the plot window's menu.

This is provided so that you can enable/disable any given option.

Enumerator
ShowHideMarkersMenuOption 

This option is titled 'Hide All Symbols' which hides all markers.

ShowHideCurvesMenuOption 

This option is titled 'Hide All Curves' which makes all curves invisible.

ShowTableMenuOption 

This option brings up the table.

No table will be available without this option.

SaveMenuOption 

This option exports the plot into a standard image format.

No conversion to a standard image format file will be available without this option, but printing will still be available.

PrintMenuOption 

This option sends the plot to a printer.

TrackMenuOption 

This option enables mouse tracking on the plot area (displays next to the mouse which x/y point you are hovering over).

This option is by default disabled.

BackgroundSwitchMenuOption 

This option enables the ability for a user to change the background color of the plot from black to white.

ShowHideGridMenuOption 

This option enables the ability for a user to enable a grid over the plot area.

RenameLabelsMenuOption 

This option enables the ability for a user to change the x/y axis labels and plot title.

SetDisplayRangeMenuOption 

This option allows the user to set the x/y axis display value ranges.

ResetScaleMenuOption 

This option provides the user with an alternative zoom out button.

ClearPlotMenuOption 

This option allows the user to delete all of the data inside the plot.

If you don't want the user deleting a custom plot item, you should disable this option.

DefaultHelpMenuOption 

Not implemented.

LineFitMenuOption 

This option allows the user to create a best fit line for any of the scatter plot data or cube plot curve data in the window.

This allows the user to create new plot curves.

ConfigurePlotMenuOption 

This option allows the user to change the curve name, color, style size, and symbol of the curve.

AllMenuOptions 

This is all of the available menu options.

Constructor & Destructor Documentation

◆ PlotWindow()

Isis::PlotWindow::PlotWindow ( QString title,
PlotCurve::Units xAxisUnits,
PlotCurve::Units yAxisUnits,
QWidget * parent,
MenuOptions optionsToProvide = AllMenuOptions )

This constructs a plot window.

The plot window graphs any curve sent to it via the addPlotCurve() method.

Parameters
titleThe window title and default plot title
xAxisUnitsThe x-bottom axis data's units, which must match any curves' units that are added to this window.
yAxisUnitsThe y-left axis data's units, which must match any curves' units that are added to this window.
parentThe Qt parent widget
optionsToProvideA bit-flag containing information on which options to provide to the users.

Member Function Documentation

◆ add()

void Isis::PlotWindow::add ( CubePlotCurve * pc)
virtual

This method adds the curves to the plot.

Parameters

References canAdd(), fillTable(), plot(), plotChanged(), replot(), and resetScale().

Referenced by dropEvent().

◆ canAdd()

bool Isis::PlotWindow::canAdd ( CubePlotCurve * curveToTest) const

This method tests whethere or not a CubePlotCurve can be successfully added to this window.

Plot curves with mismatched X/Y data from the plot's x/y axis types can not be added to the window. This does not test whether or not a user is allowed to add the curve manually, just if the curve can be added programatically.

Parameters
curveToTestThe plot curve to test for compatibility with this window
Returns
True if the curve is compatible with this window, false otherwise

Referenced by add().

◆ changePlotLabels

void Isis::PlotWindow::changePlotLabels ( )

References plotChanged(), and plotCurves().

◆ createBestFitLine

void Isis::PlotWindow::createBestFitLine ( )

Referenced by Isis::ScatterPlotWindow::ScatterPlotWindow().

◆ dragEnterEvent()

void Isis::PlotWindow::dragEnterEvent ( QDragEnterEvent * event)
protectedvirtual

When a user drags data into our plot window, we need to indicate whether or not this data is compatible with this window.

This checks userCanAddCurve() on the drag & drop data and allows or disallowed the event accordingly.

Parameters
eventThe drag event to test

◆ dropEvent()

void Isis::PlotWindow::dropEvent ( QDropEvent * event)
protectedvirtual

This is called when a user drops data into our window.

The dragEnterEvent() must have said that this curve is compatible with this window. This provides all of the available options to the user (if any) set by the creator of the drag & drop event (i.e. whether or not we can move or just copy). If there are options, we create a context menu - otherwise the default action is taken.

Parameters
eventThe drop event containing the curve to put into the current window.
