Understanding Server Data (Then generating bar graph)

in General Discussion • Other • 1 year ago

Hi,

I am new to networking in general.

I am receiving a data strand in this format. (I can control the format, for example i can change the denotation)

This strand of data is very simple and is of two ATD values, [1],[2],[1],[2]. etc

368,175,367,175,368,175,368,175,368,175,368,175,
etc

I want to create a simple bar graph of these two arrays.

How do i tell Processing that the first value is data[1], the second value is data[2], then the next is data[1].. and so on?

Thanks for reading this.

I appreciate that it is a nooby question.

Even if you could point me in the right direction - that would be great.

Simple algorithm for only two values:

String strand = "368,175,368,175,368,175,368,175,368,175,368,175";
String[] stringValues = split(strand, ",");
int[] intValues = int(stringValues);
println(intValues);
// Only two distinct values in the strand
int[] dataValues = new int[2];
// Number of occurrences of each value
int[] valueNumbers = new int[2];
// Init with first value
dataValues[0] = intValues[0];
for (int i = 0; i < intValues.length; i++)
{
int value = intValues[i];
if (value != dataValues[0])
{
// The other value
dataValues[1] = value;
// One more of these values
valueNumbers[1]++;
}
else
{
valueNumbers[0]++;
}
}
println("Data");
println(dataValues);
println("Count");
println(valueNumbers);
exit();

I suppose I could have avoided the usage of arrays there... But for more values, this structure can be reused, with an adjusted algorithm: it must iterate on all discovered values.

For more values:

String strand = "368,175,368,175,368,42,175,368,175,368,42,175,368,175,42";
String[] stringValues = split(strand, ",");
int[] intValues = int(stringValues);
// Only three distinct values in the strand
int[] dataValues = new int[3];
// Number of occurrences of each value
int[] valueNumbers = new int[3];
int counter = 1; // Number of discovered values
void setup()
{
println(intValues);
// Init with first value
dataValues[0] = intValues[0];
for (int i = 0; i < intValues.length; i++)
{
int value = intValues[i];
if (isNewValue(value))
{
// Not equal to any value in the discovered values: new one
dataValues[counter++] = value;
}
// One more of these values
valueNumbers[foundPos]++;
}
println("Data");
println(dataValues);
println("Count");
println(valueNumbers);
exit();
}
// Not very clean, OK in a class...
int foundPos;
boolean isNewValue(int value)
{
for (foundPos = 0; foundPos < counter; foundPos++)
{
if (value == dataValues[foundPos])
{
// Found a previously discovered value
return false;
}
}
return true;
}

Many thanks for the insight PhiLho.

I just need to figure out how to take these string values - and plot a bar graph with the last individual seen value for that particular string.

So i guess my next question is:

How do I define where the data is coming from? Is it something like :

myClient = new Client(this, "192.168.1.111", 80); //ip and local port

Then do i set the string strand at myClient?
