Example #5 - Creating a limits graph

This example shows how to create a simple limits graph containing two data series. Data are manualy set using the AddPoint() method of the pData class. The graph function called is drawLimitsGraph() specifying the color of the vertical line. Running this script will create a example5.png file in the current directory.

Output :

Source code :
  // Standard inclusions   

  // Dataset definition 
  $DataSet = new pData;

  // Initialise the graph
  $Test = new pChart(700,230);

  // Draw the 0 line

  // Draw the limit graph

  // Finish the graph
  $Test->drawTitle(50,22,"Example 5",50,50,50,585);
If you want to send the picture directly in a browser, replace the Render() command by Stroke().
