Verticals Colored Bar Graphs for anything (my contribution)

[TangerineDreamer]

Hi to all,
i'd like to share some colored bar graphs examples because it's very hard to find them
with the color depending of the level progression and values.
Its all verticals,could be horizontals too!

//SEVERAL COLORED BAR GRAPHS

#include <SPI.h>
#include <TFT_eSPI.h>      // Hardware-specific library

TFT_eSPI tft = TFT_eSPI(); // Invoke custom library


unsigned long currentTime = 0; 
unsigned long interval = 15;
unsigned long previousTime = 0;


uint8_t  segment;
uint8_t  width;
uint32_t levelColor[30];


void setup() {
  
  Serial.begin(115200);


  
  tft.init();
  
  tft.setRotation(2);
  
  
  tft.fillScreen(TFT_BLACK);
  
//Initialization of the colors array  
for(int i = 0;i < 20; i++){levelColor[i] = TFT_GREEN;}
for(int i = 20;i < 24; i++){levelColor[i] = TFT_YELLOW;}
for(int i = 24;i < 29; i++){levelColor[i] = TFT_RED;}

 
}



void loop(void) {

int leftHeight = map(random(200),0,200,0,30);
int rightHeight = map(random(200),0,200,0,30);
 
currentTime = millis();
  if((currentTime - previousTime)> interval)
  {
  previousTime = currentTime;
          


//------------WIDE COLORED SEGMENTED BAR GRAPH--------------- 
width = 40;
segment = 15; 
//-----------------LEFT LEVEL-------------------- 
for(int i = 0;i < leftHeight ;i++){
  
 tft.fillRect(20 , 420 - (10*i),width,(17 - segment),levelColor[i]); 
 tft.fillRect(20, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);
}
//-----------------RIGHT LEVEL-------------------- 
for(int i = 0;i < rightHeight ;i++){
  
 tft.fillRect(65 , 420 - (10*i),width,(17 - segment),levelColor[i]); 
 tft.fillRect(65, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);
}




//------------NARROW COLORED SEGMENTED BAR GRAPH--------------- 
width = 15;
segment = 2; 
//-----------------LEFT LEVEL-------------------- 
for(int i = 0;i < leftHeight ;i++){
  
 tft.fillRect(140 , 420 - (10*i),width,(10 - segment),levelColor[i]); 
 tft.fillRect(140, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);
}
//-----------------RIGHT LEVEL-------------------- 
for(int i = 0;i < rightHeight ;i++){
  
 tft.fillRect(165 , 420 - (10*i),width,(10 - segment),levelColor[i]); 
 tft.fillRect(165, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);
}

  }

//------------WIDE PLAIN BASIC COLORED BAR GRAPH---------------
width = 40;
segment = 0; 
//-----------------LEFT LEVEL--------------------            
 for(int i = 0;i < leftHeight ;i++){  
      
 tft.fillRect(220 , 420 - (10*i),width,(10 - segment),levelColor[i]); 
 tft.fillRect(220, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);
 
 }
 //-----------------RIGHT LEVEL-------------------- 
for(int i = 0;i < rightHeight ;i++){
 tft.fillRect(265 , 420 - (10*i),width,(10 - segment),levelColor[i]); 
 tft.fillRect(265, 420 -300, width, 300 - (10*i), TFT_BLACK);
 delay(5);     
}      

}

I've been searching a long time for it,glad you find them useful :)
