* change namespace indentation to 0Tim Moore2009-12-211-193/+193
| | | | | A silly change, but this works better with other tools, like git diff. I should have started the C++ files this way.
* refactor list of data sets out of GraphWidget into a global data structure.Tim Moore2009-12-081-3/+6
| | | | | | | | | | | | | | Also, add a sigc signal for broadcasting data set changes. * grapher/GraphData.hxx (GraphDataList) new typedef (getGraphData, graphDataSignal): new functions * grapher/Graph.hxx (DatasetList): remove typedef in favor of systemtap::GraphDataList * grapher/GraphWidget.cxx (GraphWidget, onGraphDataChanged): Use graphDataSignal to notice new data sets that need to be added. Use the global data set list instead of one embedded in GraphWidget. * grapher/StapParser.hxx: delete the _widget member; use signals to broadcast that there are new data sets instead of calling into the widget.
* add copyright and license to grapher filesTim Moore2009-12-071-0/+8

* option to display graph times relative to the start timeTim Moore2009-12-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | This avoids having humongous numbers displayed on the graphs' x axis. Also, the dialog for adding a data set to a graph was cleaned up. * grapher/graph-dialog.glade: Add check box for display of relative time and a label for the data set list. Force the list of data sets to be larger. * grapher/Graph.hxx (_timeBase): new member * grapher/Graph.cxx (draw): Subtract _timeBase from displayed time value. * grapher/GraphWidget.hxx (DataModelColumns): Add a column for a data set's title, which is optional at the moment. * grapher/GraphWidget.hxx (_globalTimeBase, _timeBaseInitialized, _relativeTimesButton, _displayRelativeTimes): new members * grapher/GraphWidget.hxx (GraphWidget): Hook up check button for displaying relative time. (on_expose_event): Determine base time if needed; set base time in graphs. (onDataDialogOpen): Insert graph data set's name (key) and title into the list of data sets.
* hover text on the additional graphsTim Moore2009-12-041-1/+1
| | | | | | | | | * grapher/Graph.cxx (window2GraphCoords): Take the entire graph's position into account too. * grapher/GraphWidget.cxx (GraphWidget): Hook up the data dialog's OK button. (onDataDialogOpen): If a data set doesn't have a title, use it's name (key) instead.
* Hover text for event-style graphsTim Moore2009-12-031-0/+7
| | | | | | | | | Don't draw the data value for an event; only display it in hover text. * grapher/Graph.hxx (window2GraphCoords): new function * grapher/Graph.cxx (window2GraphCoords): ditto * grapher/GraphStyle.cxx (GraphStyleEvent::dataIndexAtPoint): new function implementation.
* Make the hover text conform to data displayed.Tim Moore2009-12-021-8/+10
| | | | | | | | | Start of code to be more selective about the association between the hover text and the underling graph. Also, show the data set name in hover text. * grapher/GraphStyle.hxx (dataIndexAtPoint): New virtual function. * grapher/GraphStyle.cxx (dataIndexAtPoint): Implementation for bar graphs * grapher/GraphWidget.cxx (onHoverTimeout): Use dataIndexAtPoint.
* Refactor drawing of different styles of graph into classesTim Moore2009-12-021-65/+1
| | | | | | * grapher/GraphStyle.cxx: New file * grapher/GraphStyle.hxx: New file * grapher/Graph(draw): Move much drawing code to GraphStyle::draw
* Account for zoom factor when choosing hover textTim Moore2009-12-021-5/+5
| | | | * grapher/Graph.cxx (getTimeAtPoint): Divide by _zoomFactor too.
* some aesthetic tweaks to the grapherTim Moore2009-12-011-1/+1
| | | | | | * grapher/Graph.cxx (draw): Draw tick labels (times) below the graph. * grapher/grapher.cxx (main): Open main window with a size big enough to display an entire graph.
* Add hover text to the graph.Tim Moore2009-12-011-1/+1
| | | | | | | | | | | | | | When the graph display is paused, leaving the mouse stationary over the graph will display the data point under the pointer. * grapher/CairoWidget.hxx (CairoTextBox): new class (CairoWidget, CairoPlayButton): refector some play button-specific things from CairoWidget to CairoPlayButton. * grapher/CairoWidget.cxx (CairoTextBox::draw): new function. * grapher/GraphWidget.hxx (GraphWidget): new members for supporting hover text. * grapher/GraphWidget.cxx (on_motion_notify_event): Set up hover text box. (establishHoverTimeout, onHoverTimeout, getGraphUnderPoint): new functions.
* change time type from double to int64_tTim Moore2009-12-011-15/+22
| | | | | | | | | | | | | | * grapher/Graph.hxx (Graph): Change variables holding the time limits of the displayed graph from double to int64_t. * grapher/Graph.cxx (Graph::draw): Do calculations of time differences using int64_t. (Graph::getExtents, Graph::setExtents): Change left and right arguments to int64_t. * grapher/GraphData.hxx (GraphDataBase): Change time type to int64_t. (GraphDataBase::elementAsString): New function.

* cleanup of graph data parser, using Boost functions where usefulTim Moore2009-10-141-1/+1
| | | | | | * grapher/StapParser.cxx (commaSplit): Use Boost string split function (findTaggedValue): Return bool instead of position (ioCallback): Avoid using hard-coded string lengths

(addGraph): New method. (on_size_request): New method to pass widget's size to parent widgets * grapher/grapher.cxx (GrapherWindow constructor): add "add graph" action. (addGraph): New method.
