wxChartDir on MacOS.

[tonyvsuk]

I struggled to get wxChartDir to build on MacOS, but still managed to get an example working. Here are the steps to do so.

1. Download wxChartDir. I used a terminal window and executed "git glone https://github.com/utelle/wxchartdir.git"
2. Download ChartDirector.
3. In Xcode, add wxchartviewer.cpp to your project. This is located in wxchartdir/wxdemo/common/wxchartviewer.cpp
4. In Xcode, edit your project settings, and add the following paths to the "Header search paths".
   "ChartDirector/include/"
   "wxchartdir/include"
   "wxchartdir/wxdemo/common/"
5. I used the crosshair example. Add "wxchartdir/wxdemo/crosshair/crosshair.cpp" to your project.
6. Copy ChartDirector/libchartdir.6.dylib to your Xcode build folder.

You should now be able to display the crosshair frame using something like.
#include "~/Documents/wxchartdir/wxdemo/crosshair/crosshair.h"
void Displaychart()
{
CrossHair *pframe = new CrossHair(NULL);
pframe->Show();
}

Hope this helps.

Notes.
On first running, I had an issue where my app would not load the chartdirector dylib (it was not digitally signed). I double clicked it in Finder and opened it to get around that warning.
