Sorting ideas: Each time a sorted element is compared to a sorted element, one after the other, until the appropriate position is found to be inserted by size.The first comparison shows the chart:Algorithm implementation: Public Static

The solution can start from the top right or bottom left corner, compared to the number to be searched, take the lower left corner as an example, if the number to look for is 9, 6 is less than 9, so 6 is located in the column is less than 9, delete

Highcharts Data Representation (4)For some simple chart types, in some cases, the data can be further simplified. However, at the time of simplification, the following two conditions must be met: The chart only needs the coordinate position
