### Chart elements

In a report template, a chart consists of three basic areas: the platform, paper, and legend. The chart platform is a container for other chart elements, and the chart paper holds walls, axes, data markers, axis values, and category names.

- Chart platform
  The container of other chart elements, such as chart paper and chart legend.
- Chart wall
  The area that graphically displays the data being charted.
- Chart paper
  The canvas on which the main chart is drawn. The chart paper contains walls, axes, data markers, axis values, and category names.
- Chart legend
  The chart legend is a box which identifies the patterns or colors assigned to the data series or categories in a chart. The chart legend may contain one or more legend entries; each entry is composed of an icon and a label.
- Chart label
  A chart label can be used as the chart title or axis title. You can insert a label anywhere inside a chart.
- Axis values
  Each axis is divided by some tick marks, and each tick mark is associated with a value which is by default along the axis.
- Axis gridlines
  Lines that extend from the tick marks on an axis across the wall of a chart. They help readers of the chart easily find out what value is represented by a tick mark.
- Category names
  DBField and formula values can be used as category axis names.
- Data series names
  DBField and formula values can be used as series names.
- Data markers
  Data markers with the same pattern represent one data series. Each data marker represents one value from the chart data.
- Hint
  A hint message that displays the value of a data marker when the mouse pointer points at the data marker in Designer view mode, in HTML result, or at server runtime.
- Motion control section
  A section of a motion chart. It is composed of the following elements, using which you can make a chart move based on the value changes of the motion field bound in the motion bar.
  - Play button
    The play button controls whether the chart will be moving or static.
  - Motion bar
    The motion bar is bound with a motion field. When the value of the motion field changes, the chart will display its dynamic trend.
  - Speed control
    It allows you to control the moving speed of the chart.
  - Trail control
    Available only for bubble charts. It controls whether the chart will show a trail of previous values in bubbles or lines.
