Date Based Data
Our serial chart can accept data as date strings, date objects or time stamps. Dates on category axis are placed at logical intervals using any <a href="/tutorials/formatting-dates/">date format</a> you want. Period beginning can be marked as bold and use a different date format. Your data can be yearly, monthly, daily, hourly, up to milliseconds - the chart will handle any time span. The chart can be zoomed-in or panned, Chart scrollbar can shows a rough graph of all your data and you can use it both to scroll or to zoom the chart to desired position. <h2>Hidden bullets</h2> If you zoom-in the chart to a smaller time span, you will notice that the bullets are displayed. When zooming-out at some point bullets are hidden. This is done to avoid a messy look. You can configure this using <strong>hideBulletsCount</strong> property of the graph. <h2>Chart Scrollbar with a graph inside</h2> In the bottom (it can also be on the top) of the chart you have a chart scrollbar which can be used to zoom-in or zoom-out the chart. This scrollbar can be just a simple one or have a graph inside it to show a rough view of how data changed over the whole period of the data available. <h2>Zoomable Value Axis</h2> Besides category axis, value axis can also be zoomable - both using vertical scrollbar and cursor. In this demo value-zooming with cursor is not enabled, as we recommend using it for one direction zooming only.
