jxc6698In the chart.add argument, the first argument of the array is the serial number of cfgA, cfgB, cfgC, right?
ZeroThe API documentation has detailed instructions: Support for displaying multiple charts, configuring by inputting array parameters such as: var chart = Chart (([{...}, {...}, {...}]), for example chart one has two series, chart two has a series, chart three has a series, then adding 0 and 1 sequence IDs represents the data of the two series of chart 1, adding 2 sequence IDs refers to the data of the first series of chart 2, and sequence 3 refers to the data of the first series of chart 3.
