I want to make an animated contour plot. For achieving this
I want to copy every 500 milliseconds a column of a matrix
onto a column of another matrix. The second matrix is plotted.
As a first step I wanted to check if the data is copied
correctly from the first matrix ("RawData") to the second
one ("AnimData"). But "AnimData" is refreshed only at the time,
when the code is finishing. Using REDRAW_REFRESH has no effect,
REDRAW_REALTIME_SCOPE causes Origin to crash (???).
Funnily enough displaying a MessageBox (commented out in
the source) does refresh the matrix "AnimData".
Does anybody have an idea?
void test()
{
int iMaxRow, iMaxCol;
int iActRow, iActCol;
Matrix mRawData("RawData");
Matrix mAnimData("AnimData");
MatrixObject moRawData("RawData", 0);
MatrixObject moAnimData("AnimData", 0);
if(!mRawData || !mAnimData || !moRawData || !moAnimData)
{
printf("Error! \n");
}
iMaxRow = moRawData.GetNumRows();
iMaxCol = moRawData.GetNumCols();
for (iActRow=0; iActRow<iMaxRow; iActRow++)
{
Sleep(500);
for (iActCol=0; iActCol<iMaxCol; iActCol++) mAnimData[1][iActCol] = mRawData[iActRow][iActCol];
printf ("still there!\n");
mAnimData.Update(FALSE, REDRAW_REFRESH);
// MessageBox(GetWindow(),"");
}

Hi Mike,
thanks for the fast reply.
Using LT_execute("sec -p 0.5") does solve the problem.
Even if I don't understand as the following code for
waiting one second does not stop the whole program
but anyway has not the wished effect:
time(&StartWait);
time(&StopWait);
DiffTime = difftime(StopWait, StartWait);
while(DiffTime<1.0)
{
time(&StopWait);
DiffTime = difftime(StopWait, StartWait);
} |

I'm not sure that this will fix your problem but I suggest you use LT_execute("sec -p 0.5") instead of Sleep(500). Sleep() stops the entire program and might be preventing the update.
