To combine all values in a graph using chart.js, you can use the "reduce" function to iterate over all the values in your data array and calculate the sum. Here's an example of how you can achieve this:

1
2
3
4
5
6
7
8
// Sample data array
let data = [10, 20, 30, 40, 50];

// Combine all values in the data array
let total = data.reduce((acc, curr) => acc + curr, 0);

// Display the total value
console.log(total);


In this example, the "reduce" function takes a callback function that adds each value in the data array to an accumulator variable ("acc"). The accumulator variable is initialized to 0 in the second argument of the "reduce" function. The result will be the sum of all values in the data array, which will be displayed in the console.


You can apply a similar approach to your chart.js data to calculate the combined value and display it on your graph.
