ILI9341 encoder plotting

[dianaterminal]

ill prefix by just saying i am very new to the environment.
id like to use 3 encoders and plot there values on a graph. x axis being time and y axis being voltage. i am using KrisKasprzak ILI9341 library to a tft touch display via spi. the display is working and examples work. but i fear my approach in setting up my encoders is wrong.
might be worth mentioning that my over arching goal is to plot values and output them when triggered to an analog out pin. having the ability to manipulate the time axis and to loop segments is also of interest.
here is my code
```

#include <Encoder.h>
#include <ILI9341_t3.h>
#include <ILI9341_t3_Controls.h>
#include <font_Arial.h>
#include <Colors.h>

// Encoder setup
Encoder enc1(2, 3); // Encoder 1 connected to pins 2 and 3
Encoder enc2(4, 5); // Encoder 2 connected to pins 4 and 5
Encoder enc3(6, 7); // Encoder 3 connected to pins 6 and 7

// Display setup
#define FONT_TITLE Arial_16
#define FONT_DATA Arial_10

#define TFT_DC 9
#define TFT_CS 10

ILI9341_t3 tft = ILI9341_t3(TFT_CS, TFT_DC);

// Graph settings
#define X_ORIGIN 50
#define Y_ORIGIN 200
#define X_WIDE 250

#define X_INC 50
#define Y_LOSCALE -1

#define Y_INC 100

#define TEXTCOLOR C_WHITE

unsigned long oldTime;

float x;

int Enc1ID, Enc2ID, Enc3ID;

ILI9341_t3 Display(TFT_CS, TFT_DC);

CGraph MyGraph(&Display, X_ORIGIN, Y_ORIGIN, X_WIDE, Y_HIGH, X_LOSCALE, X_HISCALE, X_INC, Y_LOSCALE, Y_HISCALE, Y_INC);

void setup() {
Serial.begin(57600);

Display.begin();
Display.setRotation(1);
Display.fillScreen(C_BLACK);

MyGraph.init("Teensy Graphing", "Sample Number", "Encoder Position", TEXTCOLOR, GRIDCOLOR, AXISCOLOR, BACKCOLOR, PLOTCOLOR, FONT_TITLE, FONT_DATA);

Enc1ID = MyGraph.add("Encoder 1", VOLTSCOLOR);
Enc2ID = MyGraph.add("Encoder 2", SINCOLOR);
Enc3ID = MyGraph.add("Encoder 3", COSCOLOR);

MyGraph.drawGraph();
MyGraph.setMarkerSize(Enc1ID, 0);
MyGraph.setMarkerSize(Enc2ID, 1);
MyGraph.setMarkerSize(Enc3ID, 2);
}

void loop() {
long enc1Pos = enc1.read();
long enc2Pos = enc2.read();
long enc3Pos = enc3.read();

MyGraph.setX(x);

MyGraph.plot(Enc1ID, enc1Pos);
MyGraph.plot(Enc2ID, enc2Pos);
MyGraph.plot(Enc3ID, enc3Pos);

x += 1;
delay(10);
}
