please, tell me how reverse the lower part of the chart?

Answer 1

You can specify settings for the navigator.yAxis explicitly,

navigator: {
    yAxis: {
        reversed: true
    }
}

Reverse navigator y axis too | Highchart & Highstock @ jsFiddle

I strongly recommend going through the api reference of highstock and its demo site, they have some great documentation and live and running example codes, you should be able to solve most of the simple use cases from these
