```hi , i want to create a user interface in which the user will enter the sampling rate and the frequency, the interface will plot the sine wave when pressed on a button accordingly using chart series.
simply what im trying to do is this code when written on matlab,

1 fs= 96000;
2 f= 1000;
3 nCyl=1;
4 t=0:1/fs:nCyl*1/f;
5 x=sin(2*pi*f*t);
6 plot(t,x)

if you try to write this code on matlab a sine graph will appear,the thing i couldnt write as an equation in line 4, i want my user interface to give me the same sine graph after the user enters the sampling rate and frequency values.

thank you  ```

What I have tried:

i have tried the following code when pressing the button, there is no errors just the graph is wrong, it doesnt work correctly i think the equation is wrong:
```double phasecent = 0;
double samplerate = 96000;
double freq = 1000;
for (int i = 0; i < samplerate; i++)
{
double t = Math.Sin(freq * (2 * Math.PI) * (phasecent) / samplerate);
phasecent++;
double x = Math.Sin(2 *Math.PI*freq*t);
}```

And?
What does it do that you didn't expect, or not do that you did?
What have you tried to do to find out why?
Are there any error messages, and if so, where and when? What did you do to make them happen?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

Yes, bit you have still not explained what is wrong. Saying, "it doesnt work correctly" tells us nothing.

sorry, what im getting is a straight line, what i should get is a sine wave.

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.
