void OneDViewer::change_curve_color ( PlotCurve * curve = 0 )

privateslot

change the curves color

if no parameter is given try to retrieve the curve from the sender signal that is connected to this slot. We're assuming this is an QAction whos parent is the curve.

Parameters

curve the curve to change is the senders parent widget

if no parameter is given try to retrieve the curve from the sender signal that is connected to this slot. We're assuming this is an QAction whos parent is the curve.

Parameters

curve the curve to change is the senders parent widget

void OneDViewer::on_add_graph_triggered ( )

privateslot

react when addGraph action has been triggered

use the openfile dialog to get the graph. Then use the FileHandler to retrieve the data form the file.

ask the user from which source the added graph should come

if the source should be a new one, ask the user for the filename of the new source and add it to the list of sources

retrieve the list of items that are available from the source, if more than 1 ask the user which should be added

retrieve the result from the source and check if it is a 1d result

create a new data container and add the result to it

add a new curve to the plot and intialize it with the data and a random color then set up the legenditem and its context menu for the curve

and replot the plot

void OneDViewer::on_legend_checked	(	const QVariant &	item,

privateslot

react when an legend item has been clicked

toggle hide / show the curve

Parameters

item	the plot item assiciated with the legend entry
on	when true the associated curve will be shown

void OneDViewer::on_legend_right_clicked ( QPoint pos )

privateslot

react when an legend item has been selected

open a context menue at the position of the legenditem.

Parameters

pos	the position where the context menu should be opened

check if the sender of the signal is of widget type (is the legend item)

retrieve the legenditem widget and the corresponding curve, determine the position where the right click happen to be able to open the menu at this position

create the context menu and execute it (block in this function until a choice has been made).

In case this is the main curve (name is the name of the main curve), don't add the option to delete the curve. Otherwise create and connect their triggered signals to the appropriate private slots that will react on the choice.

if no parameter is given try to retrieve the curve from the sender signal that is connected to this slot. We're assuming this is an QAction whos parent is the curve.

Parameters

curve the curve to remove from the plot

void OneDViewer::replot ( )

privateslot

redraw the plot

hide /show the legend (this is a hack, since legends can't be directly hidden) retrieve all curve plots from the plot and get theier corresponding legend widget. This needs to be hidden and then the legend to be updated

set the scales to be log or linear

check if autoscale, and set the axis limits

display the axis titles

update the layout and replot the plot

save the states of the controls
