Issue

WeBWorK can generate the graphs the first time the code runs, but it cannot refresh the graphs when the code is modified. When using another account to open the same problem, the modified graphs are shown but are not refreshed after further changes

Solution

Adding:

   $refreshCachedImages = 1; 

in the pg source code of the homework question that has the dynamically generated graph.

We have created a number of template files that you can customize to use in your own WeBWorK problems.

If you are new to WeBWorK, here is a template for the basic problem structure: PG Structure template.

The templates are organized by the type of answer they accept:

Short answer

• Numerical, only one response accepted: Numeric Response template.
• Numerical, response accepted within specified tolerance: Numeric Tolerance template.
• Numerical, response accepted from list: Numeric from list template.
• String response

Multiple choice

• One correct answer, no responses anchored.
• One correct answer, one response anchored.
• More than one correct answer (anchoring would be as above, so extra template for anchoring not required).
• Answer selected from pull-down menu.
