Attractive ECharts Bar Chart

Anyone who has used ECharts knows that the key lies in the data within options. However, this implementation needs to distinguish data within a specific range in an array and assign different colors to the corresponding bars.

My Approach:

1. Since each item in the array has an index, I create another array and use the index to match the specified range of each bar in the chart, then push the corresponding colors into it.

2. The latest project presented a challenge because it involved gradient colors. The simple single-color approach was no longer suitable, so I added a separate var in options to keep the variables independent while maintaining their relationships.
