Using MeasurementStudio WaveformGraph, how to map 512 into X-axis Range of 40MHz

[daviddel]

Using Measurement Studio .NET 2010, I have an array of 512 values that I want to map to a specific range of display points or X values. For example, my display range is 40 MHz and number of points is 512; therefore, I need to post data every 78,125 Hz. How can I accomplish this?

Hi daviddel,

One option would be to use a For loop to assign a point every 78,125 HZ.  Here is some psuedo code:

myarray[512]

For i= 0 > 512

PlotXY (78125*i,myarray[i])

I hope this helps!

Thank you for your reply. What class library is PlotXY associated with? Currently, I'm using WaveformPlot.PlotY(dataArray), where dataArray contains my 512 data values.

Hi daviddel,

Sorry about my earlier post.  I overlooked the fact that you were using a waveform graph. What you would want to do is use the PlotY function as you mentioned.  Since PlotY has 7 different overloads it can take different paramaters. One of the overloads has the following prototype: PlotY(yData() As Double, start As Double, increment As Double)  For your case,the paramaters should be PlotY(dataArray,0, 78,125).

Thank you for your help, the solution worked very well.
