Chart Design Overview

Esta página describe los pasos básicos y las llamadas relacionadas con subrutinas para crear un gráfico simple.

Description:

Diseño de un gráfico puede ser tan simple como llamar dos subrutinas - uno para inicializar una nueva especificación gráfica(.CHART INITIALIZE)y uno para representar el gráfico (.CHART RENDER). El siguiente ejemplo ilustra los estados ILF necesarias para inicializar y hacer un gráfico de sectores por default (/tmp/piechart.png) usando un conjunto de datos previamente definido que consta de siete valores de los datos.

      *        Initialize Pie Chart
      PASS         PIE CHART                  FIELD            SHARE? N
      GOSUB    0CD .CHART INITIALIZE
      *        Note: We aren't showing the steps to supply the data, 
      *        see the next example
      *        Render chart
      SET      --- TEMP 256                   =      /tmp/piechart.png
      PASS     --- TEMP 256                   FIELD            SHARE? Y
      GOSUB    0CD .CHART RENDER

Mediante la adición de una subrutina adicional cuantas llamadas para establecer un título, los siete valores de datos con etiquetas del sector, y una vista 3D, un gráfico más útil puede ser prestado.
