Line Chart

Data that's arranged in columns or rows on a worksheet can be plotted in a line chart. In a line chart, category data is distributed evenly along the horizontal axis, and all value data is distributed evenly along the vertical axis. Line charts can show continuous data over time on an evenly scaled axis, making them ideal for showing trends in data at equal intervals, like months, quarters, or fiscal years.

This sample is loading a predefined template using fromJSON. You can open the sample in a new window to view the DataChart settings in the SpreadJS Designer.
