Hi, I have wrote code to access a database and a plot points on a graph to
represent the database values, but there is a problem occuring which i cannot
figure out. I am using a for loop to search the databasae values but my code
seems to just print out the last value in the database for each record
contained in the database.
For example there are 3 entrys in the datase say:
90 at index 0;
50 at index 1;
40 at index 2;
instead of plotting the points (x, 90), (x,50) and (x,40);
it just plots (x,40) 3 times.
The problem seems to be with the for loop? This probably is a coding issue and
might not be appropiate to post but i am desperate to solve this problem. Here
is the associated code.
//code to search to data base
WinPushDrawState();
Xvalue = 15;
for(index = 0; index < nbRec;)
{
RecH = (MemHandle)DmQueryRecord(db,index);
RecP = (HypertensionRecordTypePtr)MemHandleLock(RecH);
Yvalue = HypertensionRecord.DBPulseValue;
MemHandleUnlock(RecH);
//This is just code to calculate the proper position to plot the point
Yvalue = Yvalue/10;
Yvalue = YaxisIncrement * Yvalue;
Yvalue = 135 - Yvalue;
PlotPoint(Xvalue,Yvalue);
Xvalue+=5;
index++;
}
WinPopDrawState();
//Function to plot the point
static void PlotPoint(double XaxixPoint,double YaxisPoint)
{
RectangleType rect;
UInt16 cornerDiam = 0;
rect.topLeft.x = XaxixPoint;
rect.topLeft.y = YaxisPoint;
rect.extent.x = 2;
rect.extent.y = 2;
WinDrawRectangle(&rect,cornerDiam);
}
