OverRiding the DataSet
Posted by Maurice B on Jan-16-2013 06:17	\| Reply \| Monitor
Am currently using ChartDirector 5.1 with Visual C++ 10 and am using MFC. My Application is currently using an array of ?long?s for the data, can I override the chart Control getData to iterate through a long array instead of a double array?

Hi Maurice,

As far as I know, there is no "getData" method in ChartDirector. Anyway, ChartDirector expects data to be "double" values. If you have long values, we suggest you to convert them to double values first, before passing the data to ChartDirector. For example:

//convert to double array
std::vector<double> temp(myArraySize);
for (int i = 0; i < myArraySize; ++i)
temp[i] = (double)myLongArray[i];

c->addLineLayer(DoubleArray(&(temp[0]), myArraySize), .....);
