wxPlotCtrl and events in wxPlotMarker. How To?

[avico]

Hi Forum!

I use wxplotctrl sample and add marks like this:

wxPlotMarker *marca = new wxPlotMarker(wxPLOTMARKER_ELLIPSE, wxPoint2DDouble(428500.000,4594000.000), wxSize(2,2), wxGenericPen( wxGenericColour( 255, 0, 0), 1, wxSOLID ), wxNullGenericBrush);

m_plotCtrl->AddMarker(*marca);

and show in plot without problem.

At the same file i add an event like this (for test doble clik in plot) :

else if (eventType == wxEVT_PLOTCTRL_POINT_DOUBLECLICKED)
{
wxMessageDialog mensaje (this, _("Funciona"), _("Mensaje de error"), wxOK);
mensaje.ShowModal();
}

Load a sample data for test and run without problem and double clik in point data of curve show message, but double clik in mark added not.

I read files *.cpp and *.h from source of wxplotctrl but not have valid conclusion.

How to add events to a Mark added ?


And more questions:
If test add mark whit wxPLOTMARKER_RECT, mark not show a rectangular shape. Include file plotmark.h has two functions void CreateRectMarker. The fist has Create(wxPLOTMARKER_RECT, rect, wxSize(-1, -1), pen, brush); and the second has { Create(wxPLOTMARKER_RECT, wxRect2DDouble(pt.m_x, pt.m_y, 0, 0), size, pen, brush); }
(the same as wx_PLOTMARKER_ELLIPSE).

How to use the second function for display rectangular mark ?. In my test (previos definition of plotMarker whit wx_PLOTMARKER_RECT definition) not show.

Thanks!

PD: libraries used for samples are distribution of wxDev-C++ and wxplotctrl code from sourceforge.

Continue my research abut this question in wxplotMarker.

I have tested one aproximation to assign event to Marker simulate marker whit one unic point curve. This work is number of marker (curves) are small. More points -> more curves and time for drawing is large.

Plot markers are full speed. If test this loop:

[code]
wxPlotMarker marca1;
for (int i=0; i<15000; i++)
{
marca1.Create(wxPLOTMARKER_ELLIPSE, wxRect2DDouble(428600.000+0.5*i,4594000.000+0.5*i,428600.000+0.5*i,4594000.000+0.5*i), wxSize(2,2), wxGenericPen( wxGenericColour( 255, 0, 0), 1, wxSOLID ), wxNullGenericBrush, wxNullBitmap);
m_plotCtrl->AddMarker(marca1);
}
[/code]

Yes!, 15000 points!!. Draw is inmediate!!!.

If draw the same whit curve, aplication crash, and a reduction on number of point to 1000 or 2000 show curves but speed for creation are low.

Test this:

[code]

wxPlotData midato1;
for (int i=0; i<1000; i++)
{
midato1.Create(1,true);
midato1.SetXValue(0,428650.000+0.5*i);
midato1.SetYValue(0,4594100.000+.5*i);
m_plotCtrl->AddCurve(midato1);
}
[/code]

Speed for markers are fantastic, but events questions are not solved.

I need assign a event for simple/double click to a marker for show information (launch a dialog or a wxpropertygrid).

Number of markes are variable (result for a query). In exceptional case is around 8000 (all information stored).

Research continue

Hi Avico

I am experimenting with plotting using wxWidgets. Please will you tell me whether you are building wxPlotCtrl on Windows or Linux?

If you are building on Windows, did you use the pre-compiled library libplot.a or build your own?

Best regards

David

Hi DavidA

I use a precompiled version obtained from version wx-devc++ v 7.0 release candidate (in windows). Has a version for wxwidgets 2.8.10.

This package has a mount of examples for wxwidgets, included wxplotctrl in "project format", a file ".dev" for open wiht wxdevc++ and compile easily. (in certains projects, modify incorrect name of libraries linked and run without problems)

If you has interest for wxplotctrl, is a good first point. The sample project of wxplotctrl in included. Modify and compile for test options.

http://wxdsgn.sourceforge.net

alternate version has in wxPack (wxwidgets 2.8.9)

http://wxpack.sourceforge.net

I am not compilate librarie but as project for this. Require wxthigs.

avico, You are using the curves wrong way. You don't have to / shouldn't create 1000 curves. create just one, before the loop.
