Chart Elements

In a report template, a chart consists of three basic areas: the platform, paper, and legend. This topic introduces the elements a chart may contain.

• 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
  Chart legend is a box to identify the patterns or colors assigned to the data categories or series in a chart, or the colors assigned to the value ranges of a chart such as an indicator or bubble gauge chart. A chart legend may contain one or more legend entries, and each entry is composed of a mark and a label. You can show or hide the legend on a chart using shortcut menu command. Organization and stock charts do not have legend.
• Chart label
  You can use a chart label 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
  You can use DBField and formula values as category names.
• Data series names
  You can use DBField and formula values 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 you point to the data marker in Designer view mode, in HTML output, or at runtime.
• Motion control section
  A section of a motion chart. It contains the following elements, which you can use to 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 is moving or static.
  • Motion bar
    The motion bar is bound with a motion field. When the value of the motion field changes, the chart displays its dynamic trend.
  • Speed control
    It enables you to control the moving speed of the chart.
  • Trail control
    Available to bubble charts only. It controls whether the chart shows a trail of previous values in bubbles or lines.
