This Area Chart shows profit trend in Census Bureau-designated regions. Several series, each stands for a region, are colored differently. Note that areas don’t cover each other but overlap, so the color of the area that has no other area behind it is slightly different from the color of those area parts which have.
Sometimes profit might be negative, and that’s exactly the situation we’ve got in this particular chart. There is a series representing profit in the American West, and it’s been negative since 2001.
There is vertical and horizontal grids and two horizontal and vertical axes enabled in the chart, so we’ve got categories’ labels at the top and at the bottom of the chart and borders between categories behind the area series. Also, there is a vertical crosshair is enabled, so when you hover a point on a chart, all points with the same category are being hovered and highlighted, to do so byX hover mode is enabled. It makes the chart more interactive and easier to read.
The tooltips are enabled too. Their titles contain the category names, and the series names with the corresponding values are given in tooltips’ bodies.
Note that Y Axis labels have custom text formatting to avoid "k." be added to the zero label.
