Magento Dashboard Graphs not Showing

This is a very easy fix, if your dashboard graphs that show the number of orders and the turnover aren’t working all you need to do it to go to the following location:

\app\design\adminhtml\default\default\template\dashboard\graph.phtml

Then find this code:

<img src="getChartUrl(false) ?>" alt="chart" title="chart" />

Modify it to the following code:

<img src="getChartUrl(true) ?>" alt="chart" title="chart" />

Refresh your cache and et voilà!
